When packaging your items, you may wonder which film would be the right one to use. Many people confuse stretch film with shrink film, but they are not the same. Both of these films are used for entirely different purposes. The matter of fact is that there are different methods for the deployment of both types of film. One of these films needs to pass through a heat tunnel to package products. Doing the same with the other type results in a fire.
What is shrink film?
Shrink film is the packaging material that consists of polymer-based plastic. This film shrinks when it is heated at a specific temperature. Packagers or handers apply heat to this film using a heat gun or a heat tunnel.
For the packaging of small products using shrink film, using a heat gun is an appropriate option. This gun looks similar to a hairdryer. Using a heat gun to package the products is a manual process.
A heat tunnel, on the other hand, is a machine that automates the product packaging process. This setup utilizes an L-bar, a conveyer, and the heat tunnel itself. The product, loosely placed in sheet, moved along the conveyer on this setup. It reaches the L-bar, which comes down on the sheet to make it a product packet. This packet then moves into the tunnel where the application of heat causes the film to shrink around the product.
The shrink film is an ideal solution for the packaging of food items, including frozen pizza boxes and other frozen foods.
What is a stretch film?
The use of stretch film is the most traditional, yet the most effective, way to secure large pallets loaded with several product packages. The reason we call this the stretch film is that it consists of an extremely stretchable polymer-based plastic sheet. Its elasticity ensures the tight binding of products on a pallet. Many of the companies deploy stretch film using stretch wrap machines, which eliminate the need for manual work.
If you are not a large company with a bigger production facility, your packaging process will be less hectic, understandably. That could mean no need for an automated way of stretch wrapping, as you will be better off with the manual application. That’s where you can consider using a stretch wrap dispenser, which is a hand-held tool used for the deployment of stretch film over a bundle of products. However, this manual application does require a bit of labor work, which might get intense with an unexpected spike in product orders.
As mentioned above, the stretch film is an ideal solution for securing the bundles of products.
