摘要: PURPOSE: To obtain a biaxially stretched laminated film excellent in impact resistance and taste characteristics suitable for processing by specifying the internal haze per specific length of consisting an A-layer polyester A based on ethylene terephthalate or isophthalate with m.p. B-layer B thermoplastic elastomer. CONSTITUTION: In laminating metal panel composed containing 160-245 deg.C as main constitutional component wherein 140-245 elastomer are compounded, 25μm is 1-75% heat shrinkage factor thereof under 120 deg.C×30-min condition 5% less. Since no gap generated between at time stretching when 1-75%, markedly enhanced.
