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.

About Stretch Wrapping Machines

A stretch wrapping machine is a type of packaging equipment used to wrap items securely with stretch film. It works by applying stretch film around a load or a pallet, creating a tight and protective covering. The machine typically consists of a turntable or rotary arm that rotates the load while the stretch film is dispensed and wrapped around it.

Stretch wrapping machines are commonly used in warehouses, distribution centers, and manufacturing facilities for unitizing and securing loads for storage or shipment. They offer several benefits, including:

  1. Load Stability: Stretch film provides excellent load stability by securing the items together, preventing shifting or toppling during transit or storage.

  2. Protection: The stretch film acts as a barrier, protecting the wrapped items from dust, moisture, and other environmental factors.

  3. Cost-Effectiveness: Compared to other packaging methods, stretch wrapping is a cost-effective solution for bundling and securing loads, reducing the need for additional strapping or wrapping materials.

  4. Efficiency: Stretch wrapping machines automate the wrapping process, increasing efficiency and productivity in packaging operations.

  5. Versatility: Stretch wrapping machines can accommodate a variety of load sizes, shapes, and weights, making them suitable for different industries and applications.

Overall, stretch wrapping machines offer a reliable and efficient way to package and protect goods, ensuring safe transport and storage while optimizing packaging processes.

What is Shrink Wrap Packaging?

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.

Types of Shrink Wrap Machines

Shrink wrap machines are essential tools for both food packaging and industrial product packaging, offering efficient and secure wrapping solutions. 

In the food packaging sector, these machines use polyethylene or polyolefin films to tightly encase food items, providing protection from external contaminants, maintaining freshness, and extending shelf life. They are versatile enough to wrap various food products, including naked collations and tray/base card collations. 

Additionally, in industrial product packaging, shrink wrap machines are employed to package large and bulky items, machinery, or equipment. These machines ensure that the products are tightly sealed and protected during transit or storage, safeguarding them from damage or tampering. 

Depending on the specific requirements and volume of packaging, different types of shrink wrap machines, such as L-Sealers or Sleeve Sealers, may be utilized for optimal efficiency and productivity.
