Abstract:
At present, one of the most advanced developments that are used for pachaging both food and industrial goods, is Polypropylen BOPP film (bioksilno-oriented polypropylen). When printing on polymeric materials problem poor adhesion of paint - a phenomenon frequently. The reason - the non-polar substances on their surface, do not allow the paint molecules to enter into connection with the polymer molecules. Benefits techniques - easy application, low manufacturing costs, reduced the marriage. An additional advantage – the possibility of inclusion in the printing machine compact processing modules. For good paint adhesion requires two conditions: providence is a corona charge of material and its priming to improve wetting of the paint layer. Preparation of material depends largely on the technological process, respecting all the rules, regulations and standards is the result of a good print.
