The basic non-polar groups on the polyethylene molecule, is a non-polar printed score in thick plastic film, polypropylene molecule plastic film, on each structural element contains a methyl group, it weakly polar minutes group, basically belong to the non-polar polymers, so they are relatively poor affinity for ink, so before printing Before printing to after treatment can be satisfied with prints. Mostly by oxidation treatment, so as to increase the polarity, the surface structure is changed. Specific treatment methods are discharge (commonly known as the corona, EDM), flame method, UV radiation, acid (sulfuric acid, chromic acid) treatment method, such as several. And to discharge method is relatively simple and universal.
