Abstract

Improvements introduced in the object of the main patent no. 338.607, granted on december 29, 1967, by: "procedure for preparing polyolephinic films of thermosellable coating", characterized in that an uncoated film is subjected to a physical or chemical treatment that oxidizes the surface of the same to improve the adhesion properties of said surface and then it is coated, at least, on a surface with a resin comprising a composition obtained by condensation of a monoaldehyde with acrylamide or methacrylamide in the presence of an alkanol containing 1 to 6 carbon atoms, so that at least one of the amino hydrogens is replaced by -ror'groups, whose r and r' groups are respectively alkylene and alkyl groups and subsequently interpolymerizing the condensation product, at least with another unsaturated monomer and finally the coated film is recoated on its surface or coated surfaces. With a heat-sealable coating and heated to harden the resin so that it is adhesively bonded to the heat-sealable coating and base film. (Machine-translation by Google Translate, not legally binding)
