Stretch wrapping film has been used for over 30 years to protect and preserve food from moisture, dirt, and abrasion. These films allow increased food shelf lives and give the package an appealing smooth and shiny appearance. Styrenic block copolymers can be blended with polypropylene and co-extruded with ethylene vinyl acetate to form multi-layer structures suitable for food wrap applications. These films offer an excellent balance of properties combined with a low density.
