BIAXIALLY ORIENTED HIGH-DENSITY POLYETHYLENE FILMS WITH IMPROVED SEALANT SKIN

摘要

Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt.% of high-density polyethylene. Further, the multilayer film may include a first skin layer comprising an ethylene-propylene polymer, and a second skin layer comprising at least one or more a-olefin copolymers and antiblock. One or more of the at least one or more a-olefin copolymers in the second skin layer, which may be a sealant skin layer, may include at least one ethylene-propylene-butylene polymer in combination with a plastomer and/or elastomer that contain propylene, ethylene, or a combination thereof.
