Heissiegelbare Mischung aus ultraleichtem Polyethylen oder einem Plastomer mit Polypropenharz, heissiegelbare Filme und daraus hergestellte Gegenstände

摘要

Disclosed are heat sealable compositions comprising: (a) from about 30 to about 70 weight percent a low melting polymer comprising an ethylene based copolymer having a density of from about 0.88 g/cm3 to about 0.915 g/cm3, a melt index of from about 1.5 dg/min to about 7.5 dg/min, a molecular weight distribution no greater than about 3.5, and a composition breadth index greater than about 70 percent; and, (b) from about 70 to about 30 weight percent of a propylene based polymer having from about 88 mole percent to about 100 mole percent propylene and from about 12 mole percent to about 0 mole percent of an alpha-olefin other than propylene. Further disclosed are films and articles made thereof.
