FIELD: chemistry.
SUBSTANCE: film contains a polyolefin base resin and a polyolefin carrier resin which contains 5-35 wt % CaCO3. The base and carrier resins are distinguished by molecular weight, density, flow melt index and/or polydispersity. The film can be multilayered, where the first layer contains one or more compounds such as ethylene vinyl acetate, ethylene ethyl acetate and ethylene acrylic acid, and the second layer is made from polyolefin containing calcium carbonate. The calcium carbonate can be surface-treated with one or more fatty acids having 8-24 carbon atoms. The films have low rate of vapour and moisture penetration.
EFFECT: packaging materials made from said films are moisture sensitive.
