FIELD: chemistry.
SUBSTANCE: invention relates to a multilayer water-based film based on polyolefins. Proposed film comprises: a) first layer containing polyethylene having density of more than 0.94 g/cm3 and melt index less or equal to 2 g/10 min; b) second layer containing polyolefin, having density from 0.865 to 0.917 g/cm3, melt index greater than or equal to 2 g/10 min, friction coefficient (COF) greater than 0.5 in accordance with D1894 and adhesion force of more than 20 g in accordance with D5458, where second layer is first outer layer of film, and c) a third layer which is a second outer layer which contains a polyolefin and has a friction coefficient of less than 0.5 in accordance with D1894 and a bond strength of less than 20 g in accordance with D5458.
EFFECT: technical result consists in obtaining a polyethylene film, having improved twist retention properties and high rigidity.
