Abstract
A sealable film is disclosed comprising (i) a base layer comprising polypropylene and a hydrocarbon resin having a softening point of at least 140°C, and (ii) at least one top layer comprising (a) an ethylene/propylene copolymer having an ethylene content of not more than about 10% by weight, (b) a propylene/1-butene copolymer, (c) a propylene/ethylene/alpha-olefin terpolymer, or (d) a blend of two or more of (a), (b) and (c), wherein at least one of said base layer and said at least one top layer contains an anti-blocking agent or lubricant. The film possesses improved barrier properties with respect to permeability to water vapor and oxygen, and which at the same time exhibits favorable slip properties and low shrink values.
