摘要： Heat-sealable films are described which are constituted by a polyolefin film, particularly polypropylene, having on one surface thereof a layer of primer, applied in aqueous or aqueous-alcoholic solution, and chosen from: polyethylenimines, products of the condensation of urea or melamine with formaldehyde, particularly the etherified compounds; alkoxyalkyl melamine polyhydroxylates; or mixtures of the said compounds; and, on the other surface thereof, a layer of the said primer or one similar to the first, followed by a layer of vinyl, vinylidene or acrylic polymer or copolymer.The process for the production of these films includes the surface treatment of the polyolefin film by means of an electric discharge, flame or chemical agents, followed by the application of both surfaces, by means of an aqueous or aqueous-alcoholic solution, of a layer of primer chosen from: polyethylenimines, products of the condensation of urea or melamine with formaldehyde, particularly the etherified compounds; alkoxyalkyl melamine polyhydroxylates; or mixtures of the said compounds; and finally followed by the application, to one of the surfaces thus treated, of a layer of vinyl, vinylidene or acrylic polymer or copolymer. The heat-sealable films thus obtained have improved characteristics, particularly with regard to their printability, dimensional stability and residual solvent content both in the film per se, and when printed, and are particularly suitable for use in flow packing.
