How to improve after adding masterbatch, blown film printing effect of variation
Release time：2016/9/23
After we mentioned above, add masterbatch, blown film printing effect of variation of reasons, how to improve it?
Requirements for dispersing the pigment masterbatch additives (lubricant) to minimize, with the ability masterbatch plant, down to the lowest possible value (of course this pigment dispersed contradiction exists), then production out of the masterbatch, the impact on the film print quality will be minimized. (Injection masterbatch)
Another most people ignore the problem, that is, by itself, blown plastic materials can cause print quality problems. Masterbatch plant in the choice of using PE as the carrier, improper selection will cause print quality problems. Some years ago, a masterbatch plant selection South Korea imported LDPE masterbatch carrier produced as a white female, because it is a temporary change carriers, supply-side and demand-side have not thought of anything wrong. As a result, the demand side in the film how the printing does not work, always fade, the corona machine open to a maximum of the film is processed or not [even spark corona machines produce a lot of ozone, can help people smoked almost inverted) . Ink problem has been suspected, the investigation took a long time to find that kind of material containing ultra-Korea more slip agent component. Although manufactures very bright, it is not printable (this reflected South Korean factories, factory revised later this PE recipe, then there is no problem in the future). Masterbatch carrier inappropriate choice, and will have such a big impact, such as full use of such a resin blown film, the impact will be greater.
