  • Patent number: 4078113
    Abstract: A method for producing transparent or pigmented films from resin particles, of a particular class of laurolactam containing polyamide copolymers and/or terpolymer, said film suitable as a coating and/or heat melt adhesive for fabrics and other materials. The method comprises drying the resin while in the solid state until it is substantially water free, extruding the dried resin particles while heating to a temperature sufficient to volatilize and drive off unreacted monomer contaminants, but below the degradation temperature of the resin, expelling the molten resin from the extruder onto heated, sheeting dye means to form a film therefrom, dropping the film onto a substrate backing material, and running the film and backing through a roller to achieve a uniform and controlled thickness.
