AI Technical Summary
Current methods for cleaning and coating reusable PET bottles using sodium hydroxide solution cause premature wear and tear, surface roughness, shrinkage, and contamination issues, leading to reduced lifespan and inability to switch between flavored and unflavored beverages due to flavor migration.
A protective layer formed from HMDSO, HMDSN, or HMDS is applied using PECVD, which is soluble in alkaline baths, preventing surface attack and allowing for easy removal of biofilms and contaminants, combined with adhesion and barrier layers to enhance protection and reduce material usage.
The solution extends the lifespan of PET bottles, reduces material usage, and allows for versatile refilling without flavor contamination, while optimizing washing processes for reduced chemical consumption and energy use.
