Film with improved antiblocking and adhesion properties

摘要

A multilayer plastic film includes a core layer and opposed skin layers. One of the skin layers includes a blend of more than 50% by weight high-density ethylene polymer and less than 50% by weight of a polar polymer. This blended skin layer is sufficiently active to bond to an extruded, heat-sealable layer of a polar, ionomer resin with an effective bond strength and without a primer between the skin layer and ionomer resin. A metal layer preferably is included on the other skin layer.
