Stretch film, also known as stretch wrap, is a highly stretchable plastic film that is wrapped around items to secure and hold them together. It is commonly used to bundle and stabilize items during transportation and storage. Stretch film is made from linear low-density polyethylene (LLDPE) and is available in a variety of thicknesses and widths. Some stretch film also contains UV inhibitors to protect the wrapped items from sunlight. It is available in machine-grade and hand-grade forms, with machine-grade being used for high-volume applications, and hand-grade for smaller, irregular-shaped items.
