FIELD: technological processes.
SUBSTANCE: film includes one or several layers, at least one of which contains 1-10 wt % of anti-skid additive. Additive does not melt or has melting temperature that exceeds 
, has particle size in the range from 50 to 500 micron and is selected from the group that includes sand, clay, silicon dioxide, cross-linked polyethylenes, other polymers or ultra-high molecular weight polyethylene (UHMWPE). Method for film production includes preparation of resin composition for every layer and its extrusion by blowing with blowing extent in the range from 1.0 to 5.0.
EFFECT: improvement of anti-skid characteristics.
