Shrink wrap, or shrink film, is a packaging material made with polymer plastic film. Commonly used to cover pallets, it is perfect to conserve whatever it covers because when shrink film is heated will shrink tightly leaving no gaps or holes on the packaging, hence the name 'Shrink Wrap'. It can be heated using a hand-held electrical or gas shrink gun.
Shrink packaging is generally offered as:
Shrink film comes in two basic varieties: single-wound (flat) polythene tubing slit on both sides, creating two sheets on top of each other and wound separately and centrefold slit on one side before winding so that a long sheet is formed, that opens out to twice the film width.
Shrink tubing is also commonly used for shrink wrapping. It is essentially the same as centrer-fold shrink film, except that the non-folded side is sealed to create a tube.
Shrink bags are again very similar to shrink film. They are sealed on three sides to form a bag to place the product in.
