<p><P>PROBLEM TO BE SOLVED: To provide a multi-layer film for thermal lamination and a laminated sheet which can be easily thermally laminated on a sheet composed of a styrene-based polymer and has a sufficient bonding strength, and to provide a thermoformed container which maintains a sufficient bonding strength, even after executing the thermal molding of the laminated sheet and boiling it. <P>SOLUTION: The multi-layer film for thermal lamination consists of layers (A), (B) and (C), laminated in the order of the layers (A)/(B)/(C), with the layers (A) and (C) constituting the surface layers respectively. The layer (A) is composed of a polypropylene-based polymer. The layer (B) is composed of a polypropylene-based polymer of 30 to 70 wt.% and an ethylene-based polymer of 30 to 70 wt.%. The layer (C) is composed of 30 to 70 % ethylene-based polymer having a density of 0.90 to 0.97 g/cm<SP>3</SP>, of a petroleum resin of 10 to 50 wt.% having a softening point of 110 to 150°C, and of an amorphous or poorly crystalline ethylene-α-olefin random copolymer of 10 to 50 wt.%. <P>COPYRIGHT: (C)2004,JPO</p> |
