Title: MOLDABLE POLYESTER SHEET MATERIALS AND RECYCLABLE BARRIER PACKAGES MADE THEREFROM
Abstract:
Moldable sheet materials include a first layer including a first polyester, a second layer including a second polyester, and, optionally, a third layer including a third polyester. The first polyester, the second polyester, and the third polyester are the same as or different from each other of the first polyester, the second polyester, and the third polyester. The sheet materials exclude one or more of adhesives, ethylene vinyl alcohol, polyvinyl alcohol, polyvinylidene chloride, polyamides, polyolefins, polystyrenes, and the like. Molded packages made from the sheet materials exhibit desirable oxygen and water vapor barrier properties while also being suitable for recycling in a polyethylene terephthalate recycle stream.
