Stretch film or stretch wrap is a highly stretchable plastic film that is used in packaging and shipping to wrap around items to keep them in place. The elastic recovery of stretch wrap keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat.
Stretch films can be used for everything from irregularly shaped objects to uniform pallet loads. You can secure fragile items during transportation or safeguard perishables in the food industry. Stretch films are also available in various gauges and types, including machine and hand wrap.
