Abstract
A process for preparing a flexible packaging material (6) by laminating at a temperature greater or equal to 50° C. a printed substrate coated with a primer (4) comprising poly(acrylic acid) and/or poly(methacrylic acid) with another substrate coated with a thermal active material (2), to prepare a high performance flexible packaging multilayer material (6) showing improved shelf-life, without requiring curing stage of intermediate layers.
Claims10
A process for preparing a flexible packaging material comprising:
- providing a first transparent flexible substrate coated, on a surface, with a primer consisting of poly(acrylic acid) and/or poly(methacrylic acid);
- printing a liquid electrophotographic printing ink composition onto the surface of the first transparent flexible substrate;
- extruding a thermally activatable laminating material onto a surface of a second flexible substrate, wherein the second flexible substrate is separate from the first transparent flexible substrate;
- and
- contacting, under conditions of temperature greater or equal to 50° C., the surface of the second flexible substrate on which the thermally activatable laminating material is deposited with the surface of the first transparent flexible substrate printed with the liquid electrophotographic printing ink composition, thereby bonding the surface of the second flexible substrate and the surface of the first transparent flexible substrate.
