To provide a bag which is soft, good in usability, and of which outside surface is excellent in scratch resistance and which can be decorated with beautiful printing.
In the bag, a central layer is made of an ethylene-based copolymer selected from among ethylene-vinyl acetate copolymers (85-65 mass% of ethylene and 10-35 mass% of vinyl acetate) and ethylene-alkyl (meth)acrylate copolymers (85-65 mass% of ethylene and 10-35 mass% of alkyl (meth)acrylate). A propylene-ethylene random copolymer (90-99.5 mole% of propylene unit and 0.5-10 mole% of ethylene unit) of melting point 115-130°C is laminated on both sides of the central layer to obtain a laminated film 0.05-2 mm in thickness having a layer ratio of 1:2:1-1:16:1. The laminated film is high frequency-welded to manufacture the bag.
