Abstract

PURPOSE:To manufacture a stretched film of an excellent low temperature shrinkage property, by stretching a composition of which a vinylaromatic hydrocarbon polymerization block composing a block copolymer has a specified range of a molecular weight. CONSTITUTION:A block copolymer compound is manufactured by incorporating a low molecular weight vinylaromatic hydrocarbon (e.g. styrene) having a number average molecular weight less than 20,000 in a block copolymer (e.g. a styrene-butadiene block copolymer) of which a number average molecular weight of a vinylaromatic hydrocarbon polymer block is more than 10,000 and a weight ratio of a vinylaromatic hydrocarbon and a conjugated diene is 60:40-95:5. It is molded sheet like by using an extruder, then a film is manufactured by performing stretch. It is utilized for packaging etc. of perishable foodstuffs and cakes.
