    • A polyolefin multilayer film comprising (a) a polyolefinic core layer and (b) at least one skin layer adjacent to the care layer comprising about 30%-90% by weight of a propylene-ethylene-butene terpolymer and about 10%-70% by weight of a metallocene catalyzed polyethylene or a metallocene catalyzed ethylene copolymer is disclosed. Preferably, a propylene-ethylene-butene terpolymer-containing component and a metallocene catalyzed polyethylene-containing component or a metallocene catalyzed ethylene copolymer-containing component are in distinct separate phases in an incompatible blend of the propylene-ethylene-butene terpolymer-containing component and the metallocene catalyzed polyethylene-containing component or the metallocene catalyzed ethylene copolymer-containing component.
