Shrink Film

Shrink film is a material made up of polymer plastic film. When heat is applied to this material, either through use of a heat shrink machine, heat tunnel or gas gun, it shrinks around whatever it is covering to create a tight, sealed package. It is primarily used as a protective wrapping for merchandise or food items, and can also be used to wrap and secure pallet loads.

The most commonly used shrink film is polyolefin. It is available in a variety of thicknesses, clarities, strengths and shrink ratios. The two primary films are either cross-linked, or non cross-linked, and come in two basic varieties – single-wound (flat) and centrefold.

Polyolefin can be easily identified by its stretchy properties. It produces little odour and can be used with most shrink wrap systems. It is also ideal for bundling multiple products together. Other shrink films include PVC used for non-perishable goods, and several other compositions. Co-extrusions and laminations are available with specific mechanical and barrier properties for shrink wrapping food.
