LAMINATED FILM AND PROCESS FOR PRODUCING THE SAME

摘要

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