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。商业塑料，如。B。PET，不具有足够的阻断作用。通过共挤出生产的多层膜表现出这种阻隔效果，但它们的组分不能经济地分离，因此不能根据类型回收。目前的转移项目应该解决如何使用PECVD等离子体化学装备塑料薄膜的阻挡层。这些阻挡层是非常薄的（几个10 nm）SiO2层，幅材将被涂覆有该SiO2层。许多物理和材料科学问题已经成功地处理。由于与经验丰富的工业合作伙伴的合作，对于关键的技术问题也有很好的解决方案，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.
