PURPOSE:To obtain a film resistant to cracking, free from the bend whitening and sagging, and suitable as a tuned embossing, without using an impact modifier and a large amount of plasticizer, by using a specific vinyl chloride-ethylene copolymer resin as a main component. CONSTITUTION:The film composed mainly of a vinyl chloride-ethylene copolymer resin having an ethylene content of 4-8wt% and an average polymerization degree of >=700. The amount of plasticizer is suppressed to keep the Clash-Berg softening point of the film to >=40 deg.C. For producing a film for tuned embossing, the film is drawn preferably biaxially to an extent to give a sharinkage of 20-45% by the hot water test at 100 deg.C for 5min. |
