Abstract

PURPOSE:To obtain the film having excellent heat-shrinking property by preheating a thin-film containing polystyrene at a temperature up to the melting point of a block copolymer of specified styrene and butadiene from 90 deg.C and drawing the thin- film when the thin-film is drawn on the block copolymer. CONSTITUTION:When the thin-film containing the 0-50pts.wt. polytyrene in the 100pts.wt. styrene-butadiene copolymer, the content of styrene thereof is 70-93wt% and the content of butadiene thereof is 30-7wt%, is drawn in at least one direction, preferably, the lateral direction, the thin-film is preheated within a temperature range up to the melting point of said block copolymer from 90 deg.C, and drawn. Accordingly, the film, which is excellent in heat-shrinking property, transparency, slipping property, aptitude to mechanical packing, etc., is obtained.
