HIGH BARRIER LAMINATE AND PROCESS.

摘要

A process for fabricating a high barrier lamination suitable for the construction of lighter than air materials including providing a thin, two layer thermoplastic film consisting of an amorphous copolyester skin and a high crystalline polyester core; plasma treating the high crystalline polyester core layer to a surface energy of about 50 to about 68 dyne; depositing a metal barrier layer to an optical density of about 2.2 to about 3.2; and extrusion coating a linear low density polyethylene sealant layer on the amorphous copolyester skin layer.
