Abstract
A coating composition for polyolefinic products, particularly films, which consists essentially of a solution of a three-component polymeric system comprising: (a) a vinyl or vinylidene copolymer; (b) a polymer or copolymer of acrylic esters; and (c) a polyester resin obtained by condensation. The coated products and the coating process are also described.

A thermosealable coating composition for isotactic polypropylene film products which consists essentially of a solution of a three-component polymeric system as follows:
- (a) a first component selected from the group consisting of vinyl copolymer (PVC/PVA) in a relative monomer weight percent ratio between about 70/30% and 90/10%;
- (b) a second component selected from the group consisting of polymers and copolymers of acrylic esters and mixtures thereof;
- and
- (c) a third component consisting of a polyester resin obtained by condensation and being present in a weight percent ratio of from about 1-50% of the polymeric system.
As new industrial products, thermosealable polypropylene films coated with a composition consisting essentially of a solution of a dry polymeric system comprising:
- (a) a first component consisting of a vinyl copolymer (PVC/PVA) in a relative monomer ratio between about 70/30% and 90/10%;
- (b) a second component selected from the group consisting of polymers and copolymers of acrylic esters and mixtures thereof;
- and
- (c) a third component consisting of a polyester resin obtained by condensation and being present in a ratio of from about 1-50% of the polymeric system.
