摘要: A film includes a core layer including linear random alpha-olefin/vinyl aromatic copolymer; and first second outer layers an olefinic polymer; the having Young's modulus between 50,000 200,000 psi, free shrink 40 80% at 240°F, tension of 50 400 or force 20 180 grams, 240°F. First intermediate ethylene copolymer melt index less than 2.0 can be optionally included. Alternatively, 2.0; properties as disclosed above.
