FIELD: chemistry.
SUBSTANCE: group of inventions relates to the adhesive industry and can be used for gluing film-like substrates, textile fabrics and non-woven materials. Hot melt adhesive contains: a) from 50 to 85 wt. % of at least one polyolefin polymer; b) from 1 to 40 wt. % of at least one tackifying resin; c) from 0 to 15 wt. % of at least one plasticiser; and d) from 0 to 30 wt. % of at least one additive and/or additive. Polyolefin polymer is a mixture of polyolefin polymer with molecular weight Mn <10,000 g/mol in amount of 20 to 80 wt. % and second polyolefin polymer with molecular weight Mn > 10000 g/mol in amount of 20–80 wt. %.
EFFECT: high safety of product due to exclusion of substances with high migration capacity with simultaneous preservation of adhesion and flexibility.
