<p>A transparent, elastomeric, composite film structure having a core ethylene/vinyl acetate copolymer and outer layers of a low density ethylene homopolymer or copolymer with a small amount of another alpha -olefin or vinyl acetate is made by coextrusion of the polymers in a three-layer combining adapter and quenching on a chill roll. This film structure is useful as a wrapping material, especially for heat-sensitive articles.</p> |
