In MOS chip fabrication, it is used to create the insulation layer between the metal gates of the top layer and the silicon elements below. barrier coating technology for PET containers. Special plasma technology deposits a clear, glass-like coating thinner than a human hair on the bottle interior. Studies show that the coating increases oxygen barrier of a PET bottle 17-fold and [CO.sub.2] barrier 25-fold. The coating can extend the shelf life and maintain the taste and nutritional value of bever- ages like beer, carbonated soft drinks, and fruit juices. The Glaskin coating's capabilities have been proven in shelf-life tests for more than a year with brewers and beverage companies in the U.S. and Europe.

Since it is inside the bottle, it cannot be damaged by conveyors and packaging lines. Tetra Pak conducted tests of both bottle-to-bottle recycling and conversion to fiber. The tests reportedly showed that in both applications, Glaskin does not impart any noticeable change in the quality of the end product, even when recycled using 100% coated bottles. In Europe, Spendrups and Bitburger Beer are bottled in PET with the Glaskin coating. Tetra Pak expects the first U.S. applications late this year. |
