PECVD gas barrier coating for returnable PET-bottles (T04#)

为了使一次性pet瓶具有阻隔气体和敏感饮料调味物质的屏障，等离子体聚合涂层在工业上得到广泛应用。然而，对于可重复使用的pet瓶，情况并非如此，因为在重复使用过程中，由氧化硅（SiOx）制成的传统屏障涂层无法承受氢氧化钠溶液（NaOH）的清洗过程。根据在SFB-TR 87中获得的知识，将在该转移项目中开发适合该应用的涂层系统，以便将等离子技术的优势开放到可重复使用的pet瓶领域。

In order to equip disposable PET-bottles with a barrier against gases and flavouring substances for sensitive beverages, plasma polymerised coatings are widely used industrially. However, for reusable PET-bottles this not the case yet, since the conventional barrier coatings made of silicon oxide (SiOx) cannot withstand the cleaning process with sodium hydroxide solution (NaOH) in the reusing process. With the knowledge gained in the SFB-TR 87, suitable coating systems for this application will be developed in this transfer project in order to open the advantages of plasma technology to the field of reusable PET-bottles.
