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 deg.C is not less than 10% in both of MD and TD directions. The heat seal layer contains aliphatic-aromatic polyester. |
