Laminated films laminated by blocking characterized in that the cut end is joined by heat fusion, the inner layer contains a thermoplastic resin having a Shore hardness lower than the resin of the outer layer, the inner layer comprises an acid-modified polyolefin resin, the joined portion by blocking comprises strongly joined portions and weakly joined portions, the end portions are joined more strongly than the central portion, and a process for producing the same. The laminated films are stably laminated by blocking and do not separate through the laminating process and the bag-making process. |
