Tryckfärgsdekorerat förpackningsmaterial, särskilt för aseptiska förpackningar

摘要

The disclosure relates to a printing ink-decorated packaging laminate for aseptic packages of the type produced from a web of packaging material which, for sterilization purposes, is led through a bath of hydrogen peroxide prior to the reforming of the web into aseptic packages. The packaging laminate includes an outer coating of plastic which serves as décor carrier and which, on its outside, has applied décor of water-based printing ink. By selecting high density polyethylene (HDPE) as the material in the décor-carrying outer plastic coating, the above-mentioned sterilization of the packaging material may be carried out with considerably reduced consumption of hydrogen peroxide, at the same time as good adhesion between the water-based printing ink décor and the outer plastic coating is ensured.
