The heat contraction Characteristic poly lactic acid type film of the heat contraction Characteristic poly lactic acid type film null lamination structure which is obtained by the production

摘要

PROBLEM TO BE SOLVED: To provide a heat-shrinkable polylactic acid type film showing good heat shrinkability and excellent in heat sealability and impact resistance at a low temperature.;SOLUTION: The heat-shrinkable polylactic acid type film has a substrate layer and the heat seal layer provided on the surface of the substrate layer. The substrate layer is formed from a polylactic acid type film of which the heat shrinkage factor at 100°C is not less than 10% in both of MD and TD directions. The heat seal layer contains aliphatic-aromatic polyester.;COPYRIGHT: (C)2003,JPO
