摘要:
The disclosure relates to a method for producing a coated packaging material, in particular a laminate, wherein at least the following steps are carried out: a) providing a cellulose-containing substrate, b) coating at least one surface region of the substrate with a curable composition and curing the composition, forming a primer layer, and c) generating a metal-containing layer on at least one surface region of the primer layer. According to the disclosure, the composition used in step b) contains at least one ionically polymerizable monomer that is cured via ionic polymerization. The disclosure also relates to a packaging material including a cellulose-containing substrate having a layer system, wherein the layer system has at least one primer layer and a metal-containing layer, wherein the primer layer includes/is at least one polymer cured via ionic polymerization, and a packaging produced from at least one packaging material of this type.
