Product Description
Eastar A150 Copolyester is a poly(1,4-cyclohexylene-dimethylene terephthalate/isophthalate). It is produced by reacting terephthalic acid and isophthalic acid with the glycol 1,4-cyclohexanedimethanol. Eastar A150 is intended primarily for extrusion into film and sheeting for packaging applications. It has excellent hydrolytic stability and good heat stability. Eastar A150 copolyester is lawful for use in food contact applications under food additive regulations published at 21 CFR 177.1240 by the Federal Food and Drug Administration. Therefore, it is lawful for use as a packaging material for meat or poultry foods prepared under federal inspection of the U.S. Department of Agriculture regulations at 9 CFR 318.7 and 381.147.
