摘要
A biaxially oriented multilayer film having (a) a polyolefinic core layer containing (i) a thermoplastic material containing an alpha-olefin/polypropylene-containing copolymer, the thermoplastic material being in an amount of about 10% to 70% by weight of the core layer and (ii) an isotactic polypropylene-containing copolymer in an amount of greater than 0% to about 50% by weight of the core layer and (b) a skin layer containing a styrene-butadiene copolymer or a cyclic olefin copolymer is disclosed.
