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.

Abstract: A process for preparing a flexible packaging material (6) by laminating at a temperature greater or equal to 50° C. a printed substrate comprising a primer resin (4) with another substrate coated with a thermal active material (2) consisting of a polymer having an ester of acrylic or methacrylic acid content greater than or equal to 17% by weight, to prepare a high performance flexible packaging multilayer material (6) showing improved shelf-life, without requiring curing stage of intermediate layers (1-5).

Abstract: Herein is disclosed a method of coating a web with a release formulation. The method comprising: providing a coating station comprising a rotatable applicator roller to apply a release formulation coating to a web; applying a release formulation coating to a surface of the applicator roller, the release formulation comprising at least one silicone oil; feeding the web through the coating station such that the web engages with the applicator roller; and applying the release formulation coating to the web under a shearing force by rotating the applicator roller such that, at a location at which the web and the applicator roller engage, the surface of the applicator roller moves in the opposite direction to the direction the web is fed through the coating station.
