Abstract
Described herein is a process for preparing a flexible packaging material. The process may comprise: providing a printed first flexible substrate comprising an ink composition on a surface of a first flexible substrate, the ink composition comprising a first thermoplastic resin; depositing a further composition comprising a cross-linker, a white pigment and a second thermoplastic resin onto the printed ink composition such that the thermoplastic resin of the ink composition is cross-linked; and laminating the first flexible substrate with a second flexible substrate such that the ink composition, the further composition and the cross-linker are disposed between the first and second flexible substrates.

A process for preparing a flexible packaging material comprising:
- providing a first flexible substrate comprising an ink composition printed on a surface of the first flexible substrate, the printed ink composition comprising a first thermoplastic resin;
- depositing a further composition comprising a cross-linker, a white pigment and a second thermoplastic resin that is absent groups that can form a bond with the cross-linker onto the printed ink composition;
- activating the cross-linker of the further composition such that the first thermoplastic resin of the printed ink composition is cross-linked;
- and
- laminating the first flexible substrate with a second flexible substrate such that the printed ink composition and the further composition are disposed between the first and second flexible substrates.
