<p>PURPOSE:To produce a composite film having excellent barrier properties and with sophisticated print thereon, by laminating a film the printed surface of which is coated with a polyvinyliden chloride with a film coated with an adhesive, with the coated surfaces of the films being adjacent. CONSTITUTION:The surface of a plastic film 11 is desirably printed, and is coated with an aqueous polyvinyliden chloride emulsion 12, and then the moisture is evaporated to prepare the first coated film 1, while on the surface of a plastic film 21 is coated an adhesive 22 for dry lamination, and the solvent is volatilized to prepare the second coated film 2. The first and second coated films are laminated with the coated surfaces facing to one another. Thus, the composite film having excellent barrier properties and sophisticated print thereof can be produced.</p> |
