A new invisible barrier coating for PET containers
An innovative barrier coating technology that will provide invisibility to the coating but at the same time not result in reduced clarity of the PET container, called Plasmax, has been developed by SIG. Plasmax is a cutting-edge technology for coating PET bottles, wherein, a pulsed, cold-plasma process deposits a thin-layer of glass-like silicon oxide on the interior of a PET bottle. The process occurs in a vacuum chamber, where the bottles are held neck down. A lance inserted into the evacuated bottle fills it with gaseous hexamethyl disiloxane. Microwaves are then generated to decompose the gaseous precursor, resulting in a deposit of SiOx on the bottle. Carbon dioxide and water, the two by-products, are removed by the vacuum system.
