<P>PROBLEM TO BE SOLVED: To provide an easily openable package that facilitates molding, and has a stable performance. <P>SOLUTION: A multilayer sheet 20 forms a thermoformed container of an easily openable package, and has a surface layer 27 where a lid material is fused. The surface layer contains a 30 to 70 mass% polypropylene-based resin; a 10 to 30 mass% propylene-ethylene random copolymer having a 130°C or lower melting point; and a 20 to 40 mass% low density polyethylene-based resin having a 120°C or higher melting point. An under layer 26 arranged adjacent to the surface layer 27 contains, as major ingredient, a polypropylene-based resin having an isotactic pentad fraction of ≥93 mol%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
