摘要 |
<p>A method of producing a packaging laminate for aseptic packages of the type which is produced in that a web of the packaging laminate 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 material is produced in that a web of paper which has, on the one side of the web, an applied outer coating of plastic, is, for the purpose of promoting adhesion, subjected to a surface treatment changing polarity, where after the treated outer plastic coating is provided with a decor of water-based printing ink which is applied in the desired pattern on the outside of the outer plastic coating. By selecting so-called flame treating as the surface treatment of changing polarity for the outer plastic coating, the above-mentioned sterilization can be carried out with considerably reduced hydrogen peroxide consumption, at the same time as good adhesion between the water-based printing ink decor and the outer plastic coating is ensured.</p> |
