LAMINATED FILM AND PACKAGING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a laminated film which is excellent in heat resistance, impact resistance, steam barrier properties and easiness to unseal manually and can be manufactured inexpensively. SOLUTION: A layer (A) of thermoplastic polyester resin and a layer (C) of cyclic olefin resin are laminated with a layer (B) of an adhesive interlaid. The layer (A) and/or the layer (B) is biaxially oriented and, moreover, the thickness (total) of the layer (A) of the thermoplastic polyester resin is 0.5-50μm, the thickness (total) of the layer (B) of the adhesive being 0.5-20μm and the thickness (total) of the layer (C) of the cyclic olefin resin being 5-150μm.
