PURPOSE:To obtain a packaging film for semiretorting having excellent transparency and low-temperature impact resistance and stable low-temperature heat sealability and openability. CONSTITUTION:The packaging film is made from a composition prepared by adding 500-6000ppm of a lubricant to a mixture comprising 95-80wt.% ethylene/ propylene random copolymer having a melting point of 135-155 deg.C and 5-20wt.% hydrogenated styrene copolymer comprising 7-45wt% styrene monomer and 93-55wt.% butadiene. |
