Heat-laminating composite film and laminated material using the same

摘要

A heat-laminatable composite film obtained by providing, in sequence, a layer of a mixture of (B) a reactive polyurethane containing isocyanate groups therein and (C) a vinyl chloride-vinyl acetate copolymer on one surface of a film of (A) a saponified product of ethylene-vinyl acetate copolymer, or, Layer (B) and further Layer (C) on one surface of the film of (A). A laminated material obtained by heat- laminating the composite film onto at least one surface of a plasticized polyvinyl chloride layer. PPThe heat-laminatable composite film of the present invention is excellent in blocking resistance and adhesive strength. Further by heat-laminating the composite film onto the plasticized polyvinyl chloride layer, bleeding of the plasticizer in the polyvinyl chloride layer can be prevented.
