摘要

Heat-sealable polyolefin film having a low adhesiveness to the sealing bars, coated either on one side or on both sides with a composition comprising:a) 40 to 70% by weight of a copolymer of an alkylacrylate an alkylmethacrylate and an unsaturated carboxylic acid;b) 15 to 30% by weight of a copolymer of an alkylmethacry­late and/or an alkylacrylate, styrene or substituted styrenes and an unsaturated carboxylic acid; andc) 15 to 30% by weight of a copolymer of a vinyl ester and an unsaturated amide containing methylol groups.
