PROCESS FOR PLASMA COATING.

摘要

The present invention describes a method for plasma coating the inside surfaceof a polyolefin or a polylactic acid container to provide an effective barrieragainst gas transmission. The method provides a way to deposit rapidly and uniformlyvery thin, adherent and nearly defect-free layers of polyorganosiloxane andsilicon oxide (or amorphous carbon) on the inner surface of the container to achievemore than an order of magnitude increase in barrier properties.
