Stretch film is a plastic film made from linear low-density polyethylene(LLDPE) and is used to secure, bundle, and stabilize products. During application, the film is pulled and stretched around products to create tightly secured loads. Stretch film comes in a variety of widths, thicknesses, and colors for different applications. The tight, conforming look of stretch film leads it to be frequently confused with heat shrink wrap. However, the differences are significant: Heat shrink wrap requires a source of heat, is rarely used in pallet wrapping, and is not waterproof. Heat shrink wrap also tends to be more transparent and, notably, can extend shelf life.
