Abstract
A process for manufacturing a packaging material with at least two films (12,16) or foils bonded together via at least one adhesive layer (13) to form a multi-layer laminate (10) is such that at least one adhesive layer is an electron-beam-curable adhesive and the laminate (10) is radiated with electrons in order to cure the adhesive. The laminate is particularly suitable for manufacturing pouch-type forms of packaging, in particular for snack foods. The production of laminate using electron-beam-curable adhesive results in a significant reduction in throughput time and in a reduction of solvent emissions by replacing solvent-based adhesives with electron-beam-curable adhesives.
