摘要
FIELD: chemical engineering; production of the laminated multilayered welded flat film used for manufacture of welded hose-type films.;SUBSTANCE: the invention is pertaining to the laminated multilayered welded flat film for manufacture of a welded hose-type films used as a packing and a shell for food stuff. Both surface layers of the multilayered flat film are formed at least of one copolyamide and at least of one amorphous polyamide and-or at least of one homopolyamide and-or at least of a modified polyolefin. The multilayered flat film is manufactured using a method of masking, at least, of two flat films, which in turn are a single layered-or multilayered and not obligatory are biaxially stretched out. The invention allows to increase the strength of the welded seam and to improve impermeability for a water steam and oxygen.;EFFECT: the invention ensures an increased strength of the welded seams of the laminated multilayered welded flat film and its improved impermeability for a water steam and oxygen.;25 cl 5 ex
