Low-maintenance continuous Air2Air PECVD film coating via a In-Plasma concept (In-Plasma-Air2Air) (T06#)

塑料食品包装需要气体屏障来保护食品。商用塑料，例如。B.PET，不具有足够的封闭效果。共挤生产的多层膜具有这种阻隔效应，但其组分不能经济地分离，因此不能按类型回收。目前的转移项目应该解决如何使用PECVD在塑料薄膜上配备等离子体化学阻挡层。这些屏障是非常薄的(几个10 nm)二氧化硅层，用来覆盖卷筒纸。许多物理和材料科学问题都得到了成功的解决。得益于与经验丰富的行业合作伙伴的合作，对于关键的技术问题，也有了很好的解决方案，这些问题应该在转移项目中进行检查、调查和验证。

Plastic food packaging requires a gas barrier to protect food. Commercial plastics, such as. B. PET, do not have a sufficient blocking effect. Multilayer films produced by coextrusion exhibit this barrier effect, but their components cannot be separated economically, and therefore cannot be recycled according to type. The present transfer project should work out how plastic film can be plasma-chemically equipped with a barrier layer using PECVD. These barriers are very thin (a few 10 nm) SiO2 layers, with which the web is to be coated. Many physical and material science issues have been successfully dealt with. Thanks to the cooperation with experienced industrial partners, there are also very good solutions for the crucial technical questions, which should be checked, investigated and verified in the transfer project.
