WHAT IS STRETCH FILM AND WHEN SHOULD I USE IT?

March 19, 2020

Stretch film or stretch wrap is highly stretchable film typically made from linear, low-density polyethylene plastic. As a packaging material, it’s often confused with shrink wrap; however, the two are different. Stretch film is wrapped tightly around packages or objects to secure them together or keep them protected. Shrink wrap, on the other hand, is applied by first covering the item loosely; heat is then used on the shrink wrap, causing it to shrink tightly around the package.

Stretch film is best to use when you need to hold loads together for transportation or storage while shrink wrap works better for protecting single products from the elements. Shrink wrap is also widely used for covering food items such as cheese or meats.

Stretch film comes in different thicknesses and widths. They come in different gauges, bandings, hand grades, and machine grades. Enhanced versions of stretch film use higher alpha-olefins that make them more resistant to punctures and breakage. They also come in specialty variants such as colored stretch film, UV stretch wrap, anti-static stretch film, etc. The size and type of stretch film you choose depend on its intended application. The following are the top three uses for the stretch film:
