What Everyone Must Know About Stretch Film

Stretch film plays an important role in delivering and transporting most of the products we use around the world. Is commonly used to wrap products on pallets and secure them to each other and the pallet. It help to reduce product loss, injuries and discourage load tampering.   When to use Stretch Film? You usually use stretch film when you want to hold boxes and products together on a pallet. Once the boxes and products are together you can transport or store them.   Materials The most common stretch wrap material is Linear low-density polyethylene (LLDPE). Many of the stretch films are only stretched to about 100-300% in use. Once stretched, it is used to keep the load tight. But they also come in a variety of specialty films, such as: ● UV stretch film● Vented Pallet Wrap● Anti-static Stretch film● Colored Stretch film    Nano Stretch Film It is an innovative product created by Thong Guan. The Nano Stretch film has 33 layers and the thickness of the layers is measured in nanometers. Nano Stretch Film is so lightweight but at the same time strong that it can help you save up to 50% of the packaging material. Thus using Nano Stretch Film also helps save the environment and make your business more efficient.   Methods of Producing Stretch Wrap Blown Slower process but it gives higher quality, the cost of production is also higher, due to the quantity produced per hour. Cost The process is quick but the quality is not as good as blown. The costs are lower because more can be produced per hour.   Benefits of Stretch Wrap ● Loads are more secure● Minimize shipping damage● When the products are stored outdoors UVI stretch film can protect them from UV Rays● Opaque Film reduces theft and protect color products● Stretch Film maintains products clean: free of dust and moisture.● Packaging is more efficient, increasing worker productivity● Improved inventory control● Stretch film is recyclable and versatile● When you use stretch wrap your cost decrease because it’s less expensive than strapping and other types of pallet wrapping.● Stretch film is adaptable and there is an ample variety.● Stretch wrap can be used in any surface, it doesn't matter if it’s flat or pointed.   Categories and subcategories of stretch wrappers   Manual (or Hand) Wrappers: ● Extended core: This type of wrapper have very little stretch control, and is hard to handle.● Mechanical brake: This simple structure has a mechanical brake system and uses a film roll.● Pole wrappers: The Pole Wrappers has an ergonomic design that helps to wrap the bottoms and tops of loads.   Semi-Automatic Wrappers: ● Turntable wrappers: The load spins to wrap the load with the film roll.● Orbital wrappers: The film is in a vertical ring, rotating to apply the film horizontally to the load.● Rotary arm wrappers: In The Rotary Arm Wrappers the load doesn't move while the arms turn around wrapping the load.   Automatic Wrappers: Automatic wrappers are generally a variant of a semi-automatic system. They include: ● Conveyor System, this automatically loads the wrapping machine● Systems to apply, seal and cut the film. The most common ones are: ● Turntable wrappers: The load spins to wrap the load with the film roll.● Rotary arm wrappers: In The Rotary Arm Wrappers the load doesn't move while the arms turn around wrapping the load. Usually it is use for small loads because of the high speed.● Rotary ring wrappers: The rotary ring wrapper is a more balanced system. It can reach up to 160 pallets per hour. It moves up and down while the load stay static.   There are lot of manufacturers in Malaysia and around the world so you can compare prices and choose the right one for your business and your products. As you can see stretch film has many benefits, and is the best way to transport and store products as it saves time and money. So make your business more productive and efficient and start using it.

What is the Difference Between Stretch Wrap and Shrink Wrap?

What is Stretch Wrapping? Stretch wrapping consists of the use of a stretchable plastic film, that is wrapped around a set of products. This allows users the ability to tie their things together using a stretched, yet elastic hold over them. In addition, stretch films are mostly manufactured using polyethylene plastics, and help pack a large shipment together. This type of packing is ideal for products that are about to be transported as it holds them together in a secure manner and keeps them safe from various elements.   What is Shrink Wrapping? On the other hand, shrink wrapping is a loose cover and only shrinks when the heat is applied. Shrink wraps are mostly manufactured using polyolefin plastics and are used over a single product. Additionally, it can be used to combine smaller products together. This allows its users to protect the single piece, or small pieces from weather, dust, or other elements. This type of wrapping is commonly used to pack cheese, meats, vegetables, etc.   Advantages of Stretch Wrapping: Protection - With the help of stretch wrapping, you can easily secure and protect your goods from moisture and dust. Moreover, if you go for a UV film option, you can protect your goods from UV rays. Cost Effectiveness - Stretch wrapping is a less expensive option when compared to other options available on the market today. This is mainly because the equipment needed for stretch wrapping is cheaper than other equipment. Adaptability - As stretch film wrapping offers the ability to wrap a range of goods, it is more adaptable in nature than other wrapping options.   Advantages of Shrink Wrapping:  Protection - If you are looking for a way to protect your goods from all possible elements, shrink wrap is the way to go as it will suck out all the air, and leave your goods completely protected from all elements. Damage - With the help of shrink wrapping, you can easily transport or store your goods in a secure manner. Breathable - Shrink wrap has the ability to offer ventilation, which can help reduce damage caused by moisture.   What is Stretch Wrapping used for? Palletized Boxes - One of the most common uses of stretch wrapping is to cover palletized boxes. Here pallet stretch film wraps around a number of boxes that have been set in the same pallet. This helps create the perfect size and keeps them secure. Buckets - Buckets filled with liquids such as paint, oil, or dry goods are wrapped using a heavy stretch wrap. This ties them together and creates a secure body, and reliable package. Wire Reels - Stretch wrap is used to keeping wires wrapped around perfectly, so you do not end up in a huge mess of wires as untangling thousands of meters of wire is near to impossible. Electronics - Electronics might be lighter in weight than many products, but they need protection just the same. With the help of high-performance stretch film, you can easily protect your electronics.   What is Shrink Wrapping used for? Securing - While shrinking wrap might not be used in the same way, but they are at times used to help secure a box or a number of boxes.  Seals - With the help of shrink wrapping, you can easily seal any canned food or raw materials as it offers a tight wrap, which will keep the goods protected from various elements. Small Items - Shrink wrap can be used to keep your books and magazines safe from any elements, allowing you a chance to enjoy them for decades to comes.   Deciding if you are looking for high-performance stretch film, or shrink wrap depends on a number of factors. With this blog post, we hope that you can understand your needs more, and the type of wrapping you need.

5 Reasons to Replace Hand Wrap with an Automatic Pallet Wrapping Machine

If you think that hand wrapping is a better alternative than stretch film machines, think again. In fact, a stretch film machine offers the most cost effective, fastest and safest way to your packaging needs. Here are five reasons why you should replace hand wrap with an automatic pallet wrapping machine:    1.Film Cost Saving When you use a pallet wrapping machine, you avoid using too much pallet wrap because the machine stretches the film to the extent that is accurately required. Also a pallet wrapping machine will help to ensure all loads are wrapped with the same tension, making the load more secure. In fact, users can even further lower the costs by following the suggestions below:   a) Purchasing in down gauging There are many stretch film manufacturers in Malaysia you can buy stretch films in down gauging. Take a look at the following prices you can find: There are 3 types of thickness with the same stretch film weight 10kg: - One roll of 23 micron stretch film can wrap 15.5 pallets & cost per pallet is around RM5.24 (estimation)- One roll of 17 micron stretch film can wrap 21 pallets & cost per pallet is around RM3.92 (estimation)- One rolle of 12 micron stretch film can wrap 30 pallets & cost per pallet is around RM2.93 (estimation)   b) Change to pre stretched film Pre stretched film can help you save money because it has long stability and strong physical energy. Because pre stretched film has a unique and smooth consistency, it is considered one of the best wrapping materials. Moreover, it also protects the loads better than traditional wrap.  Another issue that can cost a company a lot is training the employee on how to correctly wrap the loads to ensure customer satisfaction while avoiding any injuries. There is a right way to wrap a pallet with hand wrap. Applied incorrectly, hand wrap may crush the product or allow the product to shift during transport. Pallet wrapping with a stretch wrap machine eliminates this issue. Using a stretch wrapping machine is easy and it requires little or no training at all. All it takes is pushing a button.    2. Fast Speed As we all know time is money and there is no denying that pallet wrapping machines are faster and more efficient than hand wrapping. The speed is impressive -- the machine moves several times faster than hand wrapping, and the standard results are excellent.    3. Professional Package When you wrap a pallet using high performance stretch film, the wrap machine delivers a clean professional finished product. Hand wrapping leaves the pallet looking erratic and messy. Do you want your pallet to have a professional look? With a stretch wrap machine all this is made possible.  If an operator wraps pallets by hand, you can be sure that the wrap will not be exactly the same, time and time again. A load wrapped by one operator on Monday will not be wrapped the same way as another operator on Friday. Pallet wrapping with a high performance stretch film machine solves the problem.    4. Safety for your Employees If your employees are hand wrapping, you should be concerned about their health and safety, because there are several injuries associated with this repetitive procedure, including: chronic back, shoulder and wrist pain. In addition, there are many accidents caused by hand wrapping pallets.  You know these types of injuries can endanger the life of your employees, and cost the company a lot of money and loss. It takes around 4 minutes to hand wrap a pallet; imagine the number of pallets needed to be wrapped by a single worker on one working day. This poor posture and repetitive awkward motion can cause permanent back injury.  This is why wrapping pallets with a machine is strongly recommended in order to eliminate the high risk of musculoskeletal injuries.   5. Damage Control Pallet wrapping with a stretch film machine wraps the same way every time so it reduces the potential of a pallet being damaged during transportation, and increasing customer satisfaction at the same time.  Besides these five reasons, pallet machines are incredible versatile. There are ones for small production, semi-automatic stretch wrapping, and fully automatic pallet machines, making them compatible with every production line. So look for the pallet wrapping machine you need, jumpstart work efficiency and reduce potential damage and loss.

Type of Stretch Film

Pallet stretch films have really evolved in the last decade, why? The answer is simple -- the range of Polymers available to manufacture film is much wider than it was a few years ago.  Also don’t forget Nanotechnology.   What is Nanotechnology? The science that gives us the ability to manipulate individual atoms and molecules, giving us new materials. Today we use 33 layers of stretch film instead of 9 that we used at the beginning of the 21st century.  Stretch film is used to wrap things and is made of Linear low density polyethylene (LLDPE).  By using stretch film you reduce products loss, discourage load tampering and prevent worker injury. There are a variety of widths, thicknesses, and types of stretch film. Let's look at the difference in the manufacturing process. They are several stretch film manufacturers in Malaysia and it’s easy to find the one that is good for your products.    Film Extrusion All stretch film starts with some polymeric feed stock. The majority of films include multiple layers, which include different resins and additives. Some of the additives used are: pigment (for security), tackifier (so the film can stick to itself) and UV resistance (to prevent deterioration if the products are stored outside).  The extrusion process requires the heating and compression of resin for the needed viscosity, which creates a continuous layer of plastic. Films are blown or cast.    Blown Stretch Wrap Also called blown film, it is made using the blown extrusion process. The thick layer of extruded film, form a thin walled tube and a large bubble of air is blown inside. Blown film is tougher and more resilient than cast film and it allows a greater load holding power.  Today, approximately 20 to 30% of stretch film is blown.    Advantages - Higher load and stretch capacity- Higher quality of film- Allow loads to stay better secured because it has a higher degree of memory once stretched. - Higher Tear resistance, securing loads with sharp edges.  Disadvantages - Higher cost- Poor clarity, because of the manufacturing process- Noisy when unwound from rolls   Cast Stretch Film The cast stretch film is also known as cast stretch wrap, and is manufactured using a different process -- the cast extrusion process. In a cast extrusion process, a thermoplastic material is melted and extruded through a flat onto a chill roll, where it is quenched and re-solidified.  Today, 70 to 80% of stretch wrap is manufactured using a cast extrusion process.    Advantages - Less expensive than blown film, mainly because of lower manufacturing costs.- Excellent clarity, allowing users to see the wrapped products.- Unwinds quietly from pallet wrapping machines.- Superior cling. - Can be used by wrapping machines and hand grade.- Less force to stretch.- Tear resistance.   Disadvantages - Does not offer the holding power of blown film- Less memory and tear resistance   Take note that both have a wide variety of applications and you should consult your local film experts to know which one is better for your requirements. Both will save you money and secure your products.  For example, blown stretch wrap is very resistant to puncture, so if you are wrapping sharp products or construction products, this could be the one for you. Plus it has higher levels of cling. Cast film offers more clarity, and is cheaper, so if your products are not heavy and likely to puncture, this could be for you. Before making a purchase, you should consider the following:  - Shape of your load- Type of your load- Weight of your load- Environmental Consideration, if you are wrapping in a freezer, for example:- Transport and storage- If you are using a pallet wrapping machine- The price per pound Finally, the best way to know which one to buy is to ask your technical sales representative to determine the right containment force for your load. This way you will know exactly the amount of high performance stretch film required to properly wrap each load.

High Performance Stretch Film

The purpose of high performance stretch film is to provide unitization, protection and containment properties to your pallet loads. Users are advisable to know how to do it right, or you could end up throwing money away. Wrapping your loads with stretch film is the last process on the production line, and is often overlooked. This can be an extremely costly mistake. Keep in mind that just throwing stretch film over a pallet does not make it safe for transport. If you think “Stretch film is just stretch film”, you may not be able to get all the benefits out of your stretch wrap. For example, a new technology stretch film, Nano 33 layer stretch film, is designed to improve tearing resistance with the possibility to reduce up to 50% on the consumption of plastic, and securing the cargo for transportation with excellent stability to ensure maximum safety. Make sure to discuss with your stretch film provider to learn more about it. To save and realize the huge potential of stretch film, users must understand the basic fundamentals of pre stretching the film and the terminology.   Banding Banding is when you apply multiple wraps of high performance stretch film to a certain area. This way your products are completely secure, and they find its destination in good condition.   Blown Stretch Wrap Beads of resin are fed through a heated machine that has a circular die. As this formed bubble finishes the process of being transformed into rolls of stretch film, it is cooled down by the surrounding air. This type of stretch film costs more, and is tougher than cast films.   Cast Stretch Wrap Cast film is usually quieter, more transparent, and glossier than blown film because of this process. High performance stretch film is typically tear resistance.   Cling A bonding agent added to stretch film to increase the stickiness quality of the film. Depending on the desired effect, the bonding agent is applied to one or both sides.   Pre-Stretch Pre-Stretch film is the process that permits stretch wrap to be stretched before being applied to a load. Your wrap stretch machine should be pre-stretching the stretch film. Benefits - Strength: The stretch film is so much stronger once you pass the point of permanent deformation. - Memory: The more you stretch the wrap, less memory it has. For example, if the stretch film is applied to a load without pre stretching, you can see that the film has tightened due to the film elastic memory as it tries to return. - Lower Cost: The cost of stretch film is reduced compared to wrapping a load with no pre-stretch film. For example, it is much cheaper to do it this way instead of hand wrapping.   Post-Stretch Post stretch is the stretch in the wrap created by the film tension between the film carriage and the load being wrapped. It maximizes the load retention. In the downside if the tension stretch is concentrated on the corners of a load, it can be damaged if set too high. In addition, users should be very cautious pulling the layers apart as they use the load to create the tension. Finally, this type of stretching may not be suitable to wrap every type of products, for example P.E.T bottles.   Film Force Film force, also known as film tension, is the tension created in the film. This tension is due to the the films attempting to return to its original state after been stretched. This is why it’s so important to pre-stretch the high performance stretch film.   Film Feed It is the ability to provide the film required to wrap a load while keeping the tension of the film constant.   How to Choose Stretch Film Consider these important criteria before buying high performance stretch films: - Storage Location: if you need high performance stretch film with UV protection- Product: Value, size- Load weight- Tear and puncture resistance- Pattern: stacking- Production speed- Cling- Optics- Consistency: thickness- Noise- Pallet wrapping machine- Cost- Load profile- Height- Transport distance: this include which method you will use to transport your load- Labeling- Bar Code- Gloss- Noise Make sure any stretch film that you buy meets all other requirements and criteria you may have in order to ensure customer satisfaction.

How to Choose the Right Stretch Film for Pallets

Using stretch film or stretch wrap is one of the safest, most efficient manners of moving pallets of products. Why? Because stretch wrap maintains the product right where you left it, no matter how you transport it. As you may already know, stretch wrap comes in many sizes, styles and thickness, and is not easy to determine which one to use for your products. It is a good idea to ask the stretch film manufacturer which one to use. Some of the benefits of using stretch wrap are: - It keeps items intact during storage and transportation- Provides a smooth surface to secure important information, such as, labels, instructions, product information, etc. As mentioned before, high performance stretch wrap film is available in many sizes. Smaller diameter rolls are great for small packages with low volume establishments. They measure between 2” and 5” in width. This type of stretch wrap is usually used with just one hand. High Performance stretch wrap film that rolls with widths ranging between 12” to 18” are often dispensed by hand. These widths are for short loads, or for loads which only the top or the bottom need to be wrapped. Larger stretch film rolls, 20” wide, are designed for use by pallet wrapping machines. This type of stretch films are more efficient wrapping and can reduce waste. Stretch film also has different thickness of the plastic film called gauge. The typical gauges for stretch wrap range from 63 to 80. The level of thickness determine how much the wrap can stretch without the risk of puncturing. Certainly lighter gauges are better for small, lighter loads and heavier gauges are for bigger, heavier loads. Consider the following before buying stretch film: - 30 Gauge for loads up to 800 pounds- 63 Gauge for loads up to 1300 pounds- 70 Gauge for loads up to 1600 pounds- 80 Gauge for loads up to 2200 pounds. This thickness of stretch wrap is the most common one.   How to Choose the Right Stretch Film There are five things to consider for choosing the right stretch film for pallets. 1. Load Size There are three types of load size:- Type A: This type of loads are the easiest loads to wrap. They have a uniform shape and they do not have puncture points. - Type B: This type of loads are not as uniform as Type A, and they have several film puncture points. Usually each pallet contains two to three products destined to the same location. The stretch film has to be a high performance stretch wrap. - Type C: This type of loads are a nightmare, no two loads are the same. The size and shape of the load range are all over the place. They have several puncture points and there is a difference between the load and the pallet size. The stretch film selection is very important.   2. Equipment To determine which type of stretch film to use you need to consider the type of equipment you are using. For example, you require a high performance stretch film if you are using fully automatic high speed stretch wrapper machine.   3. Product To select which stretch film type, gauge and the number of wraps you need, you have to determine the type of products you are wrapping. Consider the weight of the pallet load.   4. Special Needs You need to ask the client if they need a special requirement, such as a one side cling or UV colored stretch wrap. A one side cling is usually used when the pallet load shift in transit. And UV stretch film is used if the products will be store outside for long periods.   5. Shipping Finally, you need to consider the distance and method of shipment. It is not the same to transfer products across the country compared to across the street -- you will require a different stretch film. The distance and method of shipment are important considerations.   So here you go, the five main considerations for choosing the right stretch film for pallet. If you have any comment, or require further information, regarding stretch film, feel free to contact our friendly sales team.

The History of Stretch Wrap

Not many of us know about the history of stretch wrap. In fact, stretch wrap is more important than you may think. Just imagine sending a pallet of boxed items without stretch film covering them. Although Stretch film is taken for granted most of the time, it is very important in solving many packaging and moving problems.   What exactly is stretch wrap film? Stretch film is a highly stretchable plastic film that it is used to protect items. The plastic film keeps the items together. Stretch film is usually used to divide pallet loads, but it is also used to tie smaller items. There are different types of stretch wrap, including: - Bundling Stretch film - Hand Stretch Film - Extended Core Stretch Film - Machine Stretch Film and - Static Dissipative Film   There are two methods of producing stretch wrap: Blown It is a slower process because the resin is melted and extruded through an annular die. The quality is higher as well as the cost.   Cast The process is quicker because the film is extruded through a slot die. The quality is not as good as blown but the cost is lower. When choosing stretch film, one need to look for important things like cling, clarity, tear resistance, static discharge, etc.   History of Stretch Film Stretch film is a new invention. With many companies claiming they are the inventors of stretch film, no one really knows the exact year of invention. Why has stretch film become such a high demand? In fact, many companies had used their own stretching film to secure pallets and to transport large groups of boxes. Stretch wrap then became more efficient than ever due to new materials and manufacturing process. In fact, one will be surprised how big the pallet wrap market is today. It all began in the 1960s, when supermarkets gained popularity over local shopkeepers. As manufacturers started transporting large loads to warehouses, they needed to use pallets to move the products quickly and safely. But companies also realized they were other benefits of using stretch film wrap to secure a pallet, such as wrapping products, protects them from dust, moisture and sunlight. Moreover, there is also another benefit of using stretch wrap film -- to act as a visual disguise for the products underneath, stopping tampering and theft. In 1972, people realized that stretch film secure loads, and that’s when more and more companies started using different types of stretch wrap. The first ones were made from Low Density Polyethylene (LDPE) and Polyvinyl Chloride (PVC). Even though PVC stretched more than LDPE, PVC was more likely to tear than LDPE. This was the main reason why companies decided to use LDPE rather than PVC. By late 1970s, a new type of stretch wrap was created, the Linear Low Density Polyethylene (LLDPE). This was a huge improvement because it could stretch more, and its durability had also been increased. With LLDPE, no matter what type of load you had, it was safe as long as it was handled properly. In the 1980s, there came another change. At this time triple layered film became the new standard. In the 1990s, it was increased to five layers. In the 2000s, the new standard was between seven and nine layers. Pallet stretch films have come a long way in the last decade. Most impressive of all, now we are seeing nanotechnology.   Nanotechnology What is Nanotechnology? It is the science that allows us the ability to manipulate individual atoms and molecules. Nano Stretch Film gives stretch film a plywood effect, which improves film performance. There are many benefits in using Nano Stretch Film, such as: - Less Cost at packaging - More efficiency - Transportation is more secure - Less damages - Environment friendly compared to non nano stretch films   As you can see, the technology used to create stretch film has improved in the last decade. Now we have different types of stretch wrap for different needs, ranging from the load size to the type of product you want to protect. And trust us, with nanotechnology, more and more advanced stretch film will be invented in the near future!

How Stretch Films are Made

There are different types of stretch films that cater to different customer needs and application. So what is the best stretch film? The best stretch films are the ones that meet your goals, requirements and expectations. Factors to consider are film gauge, pre-stretch capability, puncture resistance, tear propagation, etc. The fact is, stretch film is one of the best inventions in industry application. But do you know how stretch films are made? In fact, knowing a little bit more about stretch films will help you choose the type of stretch films that are right for you, or the approach that you use to wrap your products. The first thing you need to know is that there are two ways to make stretch films: cast and blown. Both have distinct advantages and disadvantages. There are also several traits that both types of films share, such as durability, which means how easily they tear compared to other types.   Film Extrusion All stretch films begin with polymeric feed stock, which is often referred to ‘resin’. Some of the additives used in stretch films include: Pigment: for tinted or opaque films, mostly used for security reasons Tackifier: to provide cling so the film can stick to itself UV resistance: to prevent deterioration of film if they are stored outside The extrusion process involves heating and compression of resin. Resin is first melted at the right temperature for the needed viscosity, before it’s being pushed through a die where the layer of plastic is created.   Blown Stretch Film Blown stretch film is made by blown extrusion. The thermoplastic material is melted, emerges through a circular die, and a large bubble of air is blown inside. The volume of the bubble and the thickness of the extruded tube determine the thickness of the material. It stands vertically and the bubble, which may be many feet tall, allows the film to cool gradually. Often in the wind process the edges are slit off and rolls are slit width and wound in line as the film is extruded. This is a vertical process. The process is more complex than the one used to make cast stretch film, causing this type of wrap to become more expensive. Approximately 20-30% of stretch films manufactured today are blown. Blown stretch films are more opaque due to the fact that it tends to crystallize during the process. By using this type of stretch film, the visibility of your products will reduce.   Cast Stretch Films As the name of the films suggests, the process to produce is called cast extrusion. The first step requires the melting of thermoplastic material so it can go through a flat die. The melted resin goes onto a chill roll where the film becomes solid, similar to the cooling of plastic. Sometimes the film is thinned to the target gauge by winding the resulting film faster than it is extruded. This is a horizontal process. Cast stretch films make it easier to see through wrap, and the process is quieter. Cast stretch film can be used in pallet wrapping machines or you can also hand grade casts films.   Similarities Now that you know how stretch films are made, you may be asking what’s the difference between these films. But let’s begin with the similarities between cast and blown stretch film:   Both offer money saving pre stretch performance and effective load containment. Both handle a range of applications. Now let’s look at the differences between them.   Differences Blown Stretch film: Very resistant to puncture Higher levels of cling Make more noise unwinding Cloudy until stretch Bi directional tear resistance Excellent for C loads   Cast stretch films: Clearer and glossy Unwing quieter Resist Tear Propagation Great strength when using in pallet wrapping machines Forgiving Application I’m sure now you have a better idea of which one to use.   Consider these before buying any type of stretch films: shape, type and weight of your load, environmental considerations, what sort of transport and storage your product will experience, and what pre stretch percentage you expect. Remember stretch film will save you time and money, so look for the one that is best for you.
