摘要: PROBLEM TO BE SOLVED: To provide a polylactic acid-based stretched laminated film excellent in low temperature heat-sealing properties and sealing strength without damaging concealability, decorative ultraviolet cutting-off being the characteristics of compounded with an inorganic filler having biodegradability. SOLUTION: The is constituted by laminating coating layer (II), which comprises aliphatic polyester composition (D) 97-5 mass% specific copolymer (B) 3-95 acid (C) [the sum total 100 mass%], at least on one side base material (I) comprising fine particles titanium oxide kind component selected from group consisting calcium carbonate, barium sulfate, talc, silica, mica kaolin stretching obtained laminate uniaxial direction.
