PET METHOD FOR MAKING PET CONTAINERS WITH ENHANCED SILICON DIOXIDE BARRIER COATING

摘要

31. A process for applying a silicon oxide barrier coating to a PET container comprising a wall having an inner surface and an outer surface, the process comprising: (a) heating the PET container such that at least the outer surface has a temperature of from about 200 ℉ to about 383;; (b) forming a coated PET container by applying at least one silicon oxide barrier layer on at least the inner surface of the PET container while the temperature of at least the outer surface of the PET container is between about 200 ℉ and about 383 하는 step; And (c) cooling the coated PET container after step (b).
