To provide a bag which is flexible and has good usability, whose outside surface has excellent scuff resistance, and which can be beautifully printed.
The bag is prepared by using a laminated film using an ethylene-vinyl acetate copolymer as a central layer, forming a mixed resin layer comprising a random polypropylene and an α-olefin elastomer or a layer of a propylene-ethylene random copolymer (90-99.5 mol% propylene units and 0.5-10 mol% ethylene units) polymerized with a single-site catalyst and having a melting point of 115-130°C on one face, forming a mixed resin layer of a polyethylene and an ethylene-α-olefin elastomer on the other face, and performing high frequency welding of the laminate film. The outer face of the bag is the mixed resin layer comprising the random polypropylene and the α-olefin elastomer or the propylene-ethylene random copolymer of the laminated film. The inner face of the bag is the mixed resin layer of the polyethylene and the ethylene-α-olefin elastomer of the laminated film.
