Abstract
Flexible packaging materials with electrophotographically printed images or information, and processes for preparing such flexible packaging materials are disclosed.
Claims17
A flexible packaging material, comprising:
- a flexible substrate comprising a first surface;
- an electrophotographic ink composition printed on the first surface of the flexible substrate, the printed electrophotographic ink composition comprising a polymer resin comprising a copolymer of an alkylene monomer and a monomer selected from acrylic acid and methacrylic acid;
- a polymeric base layer;
- and
- a thermally activatable laminating layer co-extruded with the polymeric base layer and thermally laminated to the first surface of the flexible substrate printed with the electrophotographic ink composition, the thermally activatable laminating layer comprising a copolymer of an alkylene monomer and a monomer selected from acrylic acid and methacrylic acid.

A process for preparing a flexible packaging material, comprising:
- printing a liquid electrophotographic ink composition onto a first surface of a flexible substrate, wherein the liquid electrophotographic ink composition comprises a polymer resin comprising a copolymer of an alkylene monomer and a monomer selected from acrylic acid and methacrylic acid;
- co-extruding a polymeric base material with a thermally activatable laminating material to form a thermally activatable laminating layer disposed on a polymeric base layer, the thermally activatable laminating layer comprising a copolymer of an alkylene monomer and a monomer selected from acrylic acid and methacrylic acid, and the polymeric base layer being formed from the polymeric base material;
- and
- contacting under conditions of heat and/or pressure the thermally activatable laminating layer with the first surface of the flexible substrate comprising the printed electrophotographic ink composition.
