A process for preparing a flexible packaging material () by laminating at a temperature greater or equal to 50&#xb0; C. a printed substrate coated with a primer () comprising poly(acrylic acid) and/or poly(methacrylic acid) with another substrate coated with a thermal active material (), to prepare a high performance flexible packaging multilayer material () showing improved shelf-life, without requiring curing stage of intermediate layers.

Immediate and high performance flexible packaging applications using thermal lamination and new primer technology

Described herein is a process for preparing a flexible packaging material (). The process may comprise: providing a base material () having a first surface () and a second surface (), the first surface () having an electrostatic ink composition () printed thereon; providing a sealant layer () on the second surface () of the base material (); providing a flexible substrate () on which a thermally activatable laminating layer () has been deposited; and contacting under conditions of heat and/or pressure the thermally activatable laminating layer () disposed on the flexible substrate () with the first surface () of the base material () on which the electrostatic ink composition () is printed.

Flexible packaging material

A process for preparing a flexible packaging material () is described. The process comprising providing a first flexible substrate () having a first surface on which an ink composition () is printed, the printed ink composition comprising an ink resin comprising polyvinyl chloride, polyvinyl butyral, nitrocellulose, polyurethane, polyamide or a UV curable resin; providing a second flexible substrate (); depositing a layer of thermally activatable laminating material () onto one of a first surface of the second flexible substrate and the first surface of the first flexible substrate on which the ink composition is printed, the thermally activatable laminating material comprising a thermally activatable polymer selected from a copolymer of an alkylene monomer and an acrylic acid or methacrylic acid monomer, a copolymer of an alkylene monomer and an alkyl acrylate or alkyl methacrylate monomer, a polyurethane, an ionomer, a copolymer of alkylene monomers, a maleic anhydride modified polyalkylene and an acid modified polyolefin; and contacting under conditions of heat and/or pressure the layer of thermally activatable laminating material with the other of the second flexible substrate and the first surface of the first flexible substrate on which the ink composition is printed.

Flexible packaging materials with electrophotographically printed images or information, and processes for preparing such flexible packaging materials are disclosed.
