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 comprising one or more of a polyethylene, a bi-axially oriented polypropylene (BOPP), a polyethylene teraphthalate (PET), a paper and/or a metallic film;
- and
- a thermally activatable laminating layer disposed between and bonded to the base material and 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;
- providing a further flexible material comprising one or more of a polyethylene, a bi-axially oriented polypropylene (BOPP), a polyethylene teraphthalate (PET), a paper and/or a metallic film;
- depositing a thermally activatable laminating layer onto one of the further flexible material and the first surface of the substrate comprising the printed electrophotographic ink composition;
- and
- contacting under conditions of heat and/or pressure the thermally activatable laminating layer with the other of the further flexible material and the first surface of the substrate comprising the printed electrophotographic ink composition.
