<p>A polyamide homopolymer or copolymer film which is coated with a transparent aqueous dispersion of a polyurethane and cross-linker, with subsequent cross-linking of the urethane. The coated film is preferably uniaxially or biaxially stretched. The resulting coated film has improved adhesion to biologically derived glues which find use in packaging and laminated articles such as paperboard structures which are then shaped into boxes for consumer use.</p> |
