All Machine Stretch Wraps are made of cast film. Cast Stretch Wrap differs from "blown" stretch wrap by providing excellent clarity for reading barcodes and other load identification. Another feature of Cast Stretch Wrap is its smooth, quiet release. Used to protect your products and to stabilize loads during transit. Stretch Wrap helps reduce shipping losses from damage or theft by resisting punctures and tears. A high-strength virgin resin film enables you to pull the wrap as tight as possible. Roll dimensions are 20" x 5,000' x 80 gauge. Minimum order: 40 rolls per pallet. Also see, Stretch Wrap (Blown), Stretch Wrap (Cast) and Stretch Wrap (Narrow Wrap).
