LAMINATED POLYAMIDE FILM AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To improve the easy sliding properties under a high humidity atmosphere by laminating an easy sliding layer composed of a blend of water-soluble or water-dispersion resin with a polyolefin wax at least on one face of a base layer composed of a polyamide film. SOLUTION: An easy sliding layer composed of a blend of water-soluble or water-dispersion resin with a polyolefin wax is laminated at least on one face of a base layer composed of a polyamide film. The water-soluble or water- dispersion resin is a graft copolymer resin composed of a polyester and an acrylic polymer or a graft copolymer resin composed of a polyurethane and an acrylic polymer. In other words, a coating fluid prepared by blending a polyolefin wax with a water solution of a water-soluble resin or a water- dispersion fluid of a water-dispersion resin is applied at least on one face of a non-polyamide film to manufacture a laminated polyamide film.
