Stretch rolls (stretch film or wrap) are highly stretchable plastic films, usually made from linear low-density polyethylene (LLDPE), used to wrap, bundle, and secure items or pallets for storage and shipping. They provide protection against dust, moisture, and transit damage, offering a self-adhesive, residue-free cling that holds goods securely. Common types include hand-held rolls for manual packing and machine rolls for automated, high-volume wrapping, with sizes ranging from 6-inch to 18-inch widths.
