Abstract
Gluability of a resin-coated surface of polyester film is enhanced by applying to the surface a composition comprising ethylene vinyl acetate, nitrocellulose and rosin-modified maleic resins.
Claims59
A method of enhancing the gluability of ethylene-vinyl acetate hot melt adhesives applied to a resin-coated surface of a polyester film which comprises applying to the surface a gluability enhancing composition comprising ethylene vinyl acetate, nitrocellulose and rosin-modified maleic resin.
A method of binding a resin-coated surface of a polyester film to a second surface using ethylene-vinyl acetate hot melt adhesives comprising:
- applying to a gluing area of the resin-coated surface a gluability enhancing composition comprising ethylene vinyl acetate, nitrocellulose, and rosin-modified maleic resins;
- applying to the gluing area over the gluability enhancing composition the ethylene-vinyl acetate hot melt adhesive;
- and
- mating the second surface and the resin-coated surface.
A container having one or more joints formed by joining two mating surfaces with ethylene-vinyl acetate hot melt adhesive wherein at least one of the surfaces joined is a resin-coated surface of a polyester film to which a gluability enhancing composition comprising ethylene vinyl acetate, nitrocellulose and rosin modified maleic resins has been applied.
