Abstract
A heath sealable thermoplastic film is coated on at least one side with an acrylonitrile-containing coating containing from 25 wt. % to about 80 wt. % acrylonitrile. More specifically the film is coated on the inside with a polymeric coating comprising (i) from 25 to 50 wt. % of a nitrile such as acrylonitrile, (ii) from 40 to 75 wt. % of a monomer selected from the group consisting of an alkyl acrylate or 1,3-butadiene, and (iii) about 1 to 10 wt. % of a monomer selected from the group consisting of an ethylenically unsaturated carboxylic acid or sulfoethyl methacrylate, the coating having a calculated glass transition temperature (T.sub.g) ranging from about 10.degree. C. to less than about 50.degree. C. The outside of the film is coated with an acrylic coating composition which can contain from 0 to about 80 wt. % acrylonitrile.
