Abstract
The present invention is directed to a cling packaging film for use in wrapping food products, particularly fresh meat and produce. The film comprises a core layer containing a copolymer of ethylene and an ethylenically unsaturated polar comonomer together with an elastomeric polymer. The film further comprises a skin layer containing linear low density polyethylene. Both the core and skin layers may contain additional components. A film in accord with the present invention compares favorably with PVC food wrap film and is intended to provide a replacement therefor.
