Printing ink-decorated packaging material for aseptic packages, and a method of producing the same |
摘要 |
The disclosure relates to printing ink-decorated packaging laminate for aseptic packages of the type which is produced in that a web of paper which has an outer coating of plastic is, for the purpose of sterilization, led through a bath of hydrogen peroxide prior to the reforming of the web into aseptic packages. The packaging laminate has a décor of water-based printing ink which is applied in the desired pattern on the outside of the outer plastic coating. For the purpose of protecting the water-based printing ink décor against attack from hydrogen peroxide in connection with the sterilization process, the packaging laminate is provided with an outer layer of water-based polyethylene or water-based acid-modified polyethylene which, by means of so-called dispersion coating, is applied on the printing ink-decorated outer plastic coating after, or in connection with the application of said printing ink décor.
