Abstract
Flexible packaging materials with electrophotographically printed images or information, and processes for preparing such flexible packaging materials are disclosed.
Claims16
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 link composition comprising a polymer resin comprising a copolymer of an alkylene monomer and a monomer selected from acrylic acid and methacrylic acid;
- a base material;
- and
- a thermally activatable laminating layer extruded onto the base material and thermally laminated to the first surface of the flexible substrate printed with the electrophotographic ink composition.

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;
- extruding a thermally activatable laminating material onto a first surface of a flexible base material to form a thermally activatable laminating layer disposed on the first surface of the flexible 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.

A process for preparing a flexible packaging material, comprising:
- providing a first flexible material comprising a substrate and an electrophotographic ink composition printed onto a first surface of the substrate, wherein the printed electrophotographic ink composition comprises a polymer resin comprising a copolymer of an alkylene monomer and a monomer selected from acrylic acid and methacrylic acid;
- providing a second flexible material comprising a flexible base material with a thermally activatable laminating layer extruded onto a first surface of the flexible base material;
- and
- contacting under conditions of heat and/or pressure the thermally activatable laminating layer with the first surface of the substrate comprising the printed electrophotographic ink composition.
