Pallet Wrapping Machine - How to Choose The Right One?

Buying a pallet wrapping machine or upgrading one is a big decision and investment. As each production line is different, every company faces unique challenges when choosing and deciding on a pallet wrapping machine that is relevant to their business, products and floor space. Remember the better your equipment wraps and protects your products, the better your return of investment (ROI).    How to choose the right Pallet Wrapping Machine? There are three main questions you need to ask before buying a pallet wrapping machine: 1. How many loads and how fast are you wrapping now? How much do you wish to increase in the future? 2. What type of loads do you have? Examples: boxes, bags, shapes, fragile, etc. 3. How much money is allocated for buying a pallet wrapping machine? Let’s talk more about it.   Goals Before buying a stretch wrapper machine, you should have a clear idea what you need the machine to do. You need to think through all the details of your production line.  If your business is switching from hand wrapping, you can start by trying an automatic stretch wrapper or semi automatic stretch wrapper. You will see a huge difference in terms of safety production, consistency and an increase in your return of investment.  To define your wrapping goals, you need to ask yourself: What type of production does your business have now?  - Seasonally- In five years- In ten years With these information you can find out what type of stretch wrapper machine is enough for your production. You can definitely start with a semi automatic stretch wrapping machine and upgrade to full automation in the future.  Moreover, it’s equally important to determine the features you need in your wrapping machine. This can be a low profile turntable or a top sheet dispenser to protect a pallet load from the sun and the rain. By doing this, you can narrow your choices and consider which is the right one for you.  In addition, consider how your pallet loads are created, how they move and the space you have for a wrapper machine.  Once you determine your needs and goals, you are ready to seek out the most suitable stretch wrapping machine.    Options Let’s take a look at the available options: Turntable This stretch wrap system places a load on a turntable. The turntable rotates to dispense the stretch film. Depending on the height of the load, you can wrap around 45-55 loads per hour. It’s key to consistently maintain the correct film tension. Turntable is a great option if you have stable loads and a low to medium production rate.  Rotary arm  This stretch wrap system uses an overhead arm that rotates around the load to apply the wrapping film. In this type of system, the load does not rotate so it can wrap at high speed -- best for lighter, fragile, heavier and unstable loads.  This stretch wrap system maintains precise, consistent film tension. It has a production rate of up to 95 loads per hour.    Stretch hood This wrapping system can secure a wide range of pallet loads. This type of wrapping machine it is more expensive than rotary or turntable but the benefits are greater.  Stretch hood optimizes product safety because it protects against humidity, UV and other weather elements. It is also against cargo shift during transport.  The Stretch hood system produces a transparent hood to ensure product visibility and minimizes wrap film usage. This stretch system wraps up to 100 loads per hour.    Automation In addition to the three types of pallet wrap systems as mentioned above, you shall also choose the degree of automation: manual, semi-automatic and automatic.  - Manual: this level of automation is better in low output settings.  - Semi-automatic: this level of automation includes turntable wrappers and rotary arm machines. It wraps automatically but you need an employee to place unwrapped loads and pick up the wrapped ones.  - Fully automatic equipment: it wraps film automatically (applied, cut and sealed). This fully automatic wrappers are ideally for high output packaging.   To know which type of pallet wrapping machine is right for you, consider all the factors above, identify the type of pallet loads you have and the wrapping rate you want, and finally make your decision based in your budget.  There are many stretch film manufacturers in Malaysia that can recommend the best pallet wrapping machine for your business and products. Remember to choose wisely to protect your products and investment.

80 Gauge Stretch Wrap

So what exactly is 80 gauge stretch wrap? If you are familiar with stretch wrap, the term 80 gauge stretch wrap should be something you are familiar with. But if you are not, feel free to read on to find out everything about 80 gauge stretch wrap.  The term 80 gauge stretch film refers to the thickness of the wrap. It’s the most common gauge, known for being very versatile and for handling a variety of applications.  It’s great for loads up to 2200-2400 pounds. When you use 80 gauge stretch film in a pallet wrapping machine, wrapping is more efficient and waste can be reduced. In fact, it has the same strength as 12”-20” hand stretch wrap. But what exactly is a gauge? A gauge is a measurement to measure thin plastics. There are other measures when referring to stretch wrap with the most common ones being gauge, micron and mil. A 20 micron stretch wrap has the same thickness of an 80 gauge stretch film. But keep in mind that even though two stretch films have the same thickness, it does not mean they are of the same quality.    What are the main differences between 80 stretch wrap? As mentioned, two stretch films with the same thickness do not necessarily have the same film quality.  A true 80 gauge stretch wrap can be stretched up to 200% of its original length. But this can vary depending on the type of extrusion process.  There are two different kinds of extrusion process: Blown and Cast. Each extrusion process will produce different film characteristics.  Let’s take a look at everything in further detail.    Blown versus Cast 80 Gauge Stretch film As mentioned, a standard 80 gauge stretch film will have different characteristics depending on the manufacturing process.  So what is the difference between cast extrusion and blown extrusion?   Cast Extrusion Stretch Film Cast extrusion cools film resins with chilled rollers. This process allows cast stretch film to have better clarity and it requires less force to stretch. Plus it increases tear resistance and it unwinds quietly from pallet wrapping machines. Cast extrusion stretch film offers a superior cling.  Some advantages of cast stretch films are that it is less expensive and wrapped products can be seen with more clarity. However, cast stretch film has less memory and tear resistance than blown stretch wrap.     Blow Extrusion Stretch Film Blow extrusion cools film resin with air. This process allows stretch film to be tougher and more resilient than cast film.  Blown stretch wrap offers high load and stretch capacity and it has a higher tear resistance. On the other hand, it is also more expensive, noisy when unwound from rolls, and has poor clarity. The most common differences between 80 gauge cast stretch film and 80 gauge blown stretch film are:    80 Gauge Cast Stretch film   - Clearer  - Less noise unwinding  - Less puncture resistance   80 Gauge Blown Stretch Film - Loud unwind - Hazy - Higher puncture resistance - Higher cost   So if you have been using a blown gauge stretch wrap, and happen to try a cast 80 gauge stretch film, you will notice the difference between the two films.  In fact, one can determine if a stretch film is a true 80 gauge stretch wrap by using a micrometer to check the film thickness. A micrometer is a measuring tool and it is used to measure the thickness of objects. You can also do a film thickness equation to determine the thickness of stretch wrap.    Thickness Equation In order to use the thick equation, find out the weight of an unused roll of stretch wrap. Just use the formula below to determine the thickness of stretch films: Roll Weight ÷ Roll Width ÷ Roll Length ÷ 12 x 30,000 = Film Thickness In short, 80 gauge stretch film offers more efficient wrapping and minimizes waste. It also has superior stretchability as compared to normal stretch films.

Stretch Wrapping vs. Shrink Wrapping

Stretch wrap and shrink wrap are sometimes said to be similar because they are both transparent and are made to hold products. However, there is a vast difference between stretch packaging and shrink packaging.    First of all, stretch film is made, in most cases, from polyethylene. It can be used to wrap a lot of items and it is capable of holding the products tightly thanks to its elasticity. On the other hand, shrink wraps are made from polyolefin plastics, and it shrinks to fit the products when heat is applied.  Stretch wrap is used for holding loads and products together on a pallet for transportation or storage purposes.  There are many types of stretch wraps like: - UV stretch wrap- High performance stretch wrap film- Vented Pallet Wrap- Anti-static stretch film- Colored Stretch film- Pre-Stretched film, etc.  Stretch wrap is employed to protect a single product from dust or weather. Sometimes it can be used to tightly combine smaller items together. It can also be very useful to cover foods, such as cheese, meats and vegetables.    Advantages of Stretch Wrap Secure Stretch wrap protects and secure products from dust and weather. If you choose a UV stretch film, you can also protect your items from the sun. Better price Stretch film is cheaper than other types of pallet wrapping. The equipment needed for stretch wrapping is less expensive than other forms of wrapping.  Versatility Since stretch wrap comes in many styles, you will have no problem finding one that suits your needs.    Advantages of Shrink Wrap Protective Shrink wrap is great for securing and protective products from weather, moist, dirt and damage. Used correctly, shrink wrap should not have any problems transporting your products from one place to another. Ventilation You can reduce any damage caused by moist when using shrink wrap because it has the option of being ventilated.   Equipment For both wraps, you will need special equipment to wrap your products.  Stretch Film Equipment Manual If you are wrapping less than 15 loads per day, you can use manual wrappers. Manual wrappers include the extended core with a film extension used as a handle. They also have mechanical brakes, and they use pole wrappers for easier use.  Pallet wrapping machines are used to reduce waste and to increase efficiency. You can choose: Semi-automatic machines Semi automatic machines require an operator to place the pallet loads on the machine. The pallet wrapping machine then applies the stretch film vertically and wraps the pallet load.  Automatic wrappers  The fully automatic stretch wrappers machines eliminate the need for an operator to place the pallet loads. They reduce the number of employees and time needed to unitize each pallet load.   Shrink Equipment If you are using any type of shrink wrap you will need a heating machine. There are different types of shrink wrap machines available for heating: - Heat Guns: They release a stream of hot air and they are necessary for more professional looking shrink wrap jobs.  - Shrink tunnels: They are mounted over or around a conveyor system. The products have the shrink film loosely applied, with heat the film shrinks to fit perfectly around the item.    For the shrink wrap, you need 300 degrees Fahrenheit to shrink perfectly.  Before the products are ready for heating, the shrink wrap sealing machines will need to cut and seal the shrink. Once this has been done, you can tighten the plastic.  As you can see, both films have made packaging for storage and transportation easy and economic. Thanks to stretch film and shrink films, the packed items are protected to avoid any damage. These wraps protect the goods from dust, dirt and weather, and help users to save time and money.    In short, stretch film and shrink wrap are completely different. Shrink wrap is mostly used for items like food, pharmaceutical and in the retail industry while stretch film is usually used for transportation purposes.  If you have questions regarding Stretch Wrapping and Shrink Wrapping, don’t hesitate to contact our friendly staff at https://www.thongguan.com/contact-us

Fun Facts about Stretch Film

Stretch film is mainly used for storage and transportation, and it is made from an incredibly durable material. If your business transports a lot of products or has a lot of inventory, it’s a good idea to consider using stretch film, to save time, money and to protect your products.  However, not all stretch wraps are created equal. Check out some of the interesting facts that you probably don’t know about stretch film.     What is Stretch Film Made of? Stretch wrap is a plastic film that is wrapped around products. It is a complicated process to make stretch film, and many different types of resins and additives are used in the process. One thing is for sure: it all starts as small plastic pellets of polymeric.  There are different types of additives used in the manufacturing process, and they all depend on the kind of film to be created. Additives can make the film stickier, or it can influence pigment for tinted films.  The resin should be heated and compressed, and once this is done, it’s cut with a die machine, creating a smooth layer of plastic.    Cast Stretch As the name suggests, cast stretch wrap is manufactured using a cast extrusion process. Cast stretch film process allows to have: - Excellent clarity- Less force to stretch- More tear resistance- Unwind quietly from pallet wrapping machines- Superior cling This type of film is available for both machine grade and hand grade.    Blown Stretch Blow stretch wrap is manufactured using the blown extrusion process. This type of film is tougher and more resilient than cast film. It has a greater load holding power because of the higher mechanical properties of blown film. It is also noisier when it unwinds, and it’s more expensive.   Different Sizes Stretch film comes in different sizes, so make sure you choose the right one for your application. They have different widths and thickness, so feel free to ask an expert before you buy one. Remember you don’t want to use a 150 gauge stretch film when 60 gauge would be enough.  Also keep in mind that the thinner the stretch is, the less wrapping force it provides. And due to an increased number of film breaks, you will need to use multiple layers. So if your product is big and heavy, it is a good idea to use a thicker stretch film. This way you can save money and time.   Stretch Film Uses Stretch film in Malaysia is commonly used in factories, manufacturing and storage. The main purpose of stretch film is to secure loads of items, for storage or transportation.  Stretch film is wrapped around products to make sure they are secure and protected from outside elements.  Another use of stretch film is for transporting furniture to protect them while they are inside the moving truck. In fact, many fragile items, such as windows and mirrors are also transported wrapped in stretch film.  Stretch film protects your items from: - The sun, if you use UV stretch film- Rain- Dust- Moisture- Debris and- Thieves Recycle Many people are concerned about using too much plastic to wrap their products, but you should know that stretch film is recyclable.  If you have any doubt on how to recycle, feel free to ask the friendly staff at Thong Guan, your stretch film manufacturer in Malaysia.   Save Money Did you know that pre-stretch film can help you save money? When you use pre-stretch film to wrap your products, you can use less to keep your load safe. So if you want to save money, go for high quality pre-stretch film.    In a Nutshell  As you can see, there are various benefits of using stretch film, and it is perfect for both small and large businesses. In fact, stretch film is a very clean material that helps you keep away rodents and pests in your storage room. Stretch film can also be used to protect items from the environment. It protects your products from the sun, rain, dust and even dew if left outside.   Lastly, stretch film is usually purchased by weight, and there is a set price per roll. Experienced stretch film manufacturer in Malaysia, such as Thong Guan can help you decide which type and how much stretch film you will need for each of your loads. Having an exact measurement helps you save money in the long run because the ideal amount of stretch film is determined by the shape, type and weight of your load.
