FIELD: chemical industry; methods of production of elongated multilayered polyolefin films.
SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular to the method of production of the elongated multilayered polyolefin films. The film has at least one crust-forming outer layer with the depth of 0.5-5 microns, which one is made out of the composition based on an copolymer -ethylene with 3-30 mass % of vinyl acetate with the melt index from 1 - 30 g/10 minutes. The films have rather stable strength of the heat sealing seams.
EFFECT: the invention ensures production of elongated multilayered polyolefin films with the rather stable strength of the heat sealing seams.
