EASY ADHESION POLYAMIDE FILM AND PRODUCTION METHOD THEREFOR

摘要

Disclosed is a highly adhesive polyamide film which is provided with a base polyamide film, and a primer layer formed on at least one surface of the base polyamide film, where said primer layer contains an anionic water-dispersible polyurethane resin. The primer layer has a thickness between 0.025 and 0.250 µm, inclusive. The anionic water-dispersible polyurethane resin has a film elasticity of at least 250%, and a tensile strength of at least 20 MPa. The highly adhesive polyamide film generates a total of no more than 0.50 µg/g of volatile alkaline components when heat treated for 10 minutes at 200ºC under a helium atmosphere.
