PROBLEM TO BE SOLVED: To provide an inexpensive laminated film for packaging containers which saves the amount of a peeling film and can be produced by a simple apparatus without requiring an advanced clean room. SOLUTION: The laminated film for packaging containers is produced by processing a laminated film obtained by a coextrusion tubular film process. The laminated film includes at least two layers, the outermost layer (11) is made of a gas-barrier resin, and the innermost layer (12) is made of a heat-sealable resin (in addition, an inner layer adjoining the outermost layer, when heat-sealed, is composed of a gas-barrier resin and an insoluble thermoplastic resin). In both end edges in the longitudinal direction or in the vicinities of both ends, peeling spaces (13) formed by cutting the outermost layer (11) and peeling it in a constant width along the cutting line are arranged, respectively. The outermost layer (11) can be peeled by using each peeling space. COPYRIGHT: (C)2007,JPO&INPIT
