Stretch wrap or stretch film, sometimes known as pallet wrap, is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound.

Stretch wrap can have several functions:
Improved stability of products or packages, forming a unit load
More efficient handling and storage of unit loads
Some degree of dust and moisture protection
Some degree of tamper resistance and resistance to package pilferage
Some degree of sun protection (UV stretch wraps)
