Classification: CPC C  B | IPC B  C

Claim 19:
20. A multilayer container, the container comprising:
an outer layer defining an exterior surface, an inner layer defining an interior surface and an interior space, and a clear barrier layer disposed between the outer layer and the inner layer, wherein:
the inner layer and the outer layer comprise poly(ethylene terephthalate) (PET);
the barrier layer is a 2,5-furandicarboxylate and terephthalate co-polyester consisting essentially of two carboxylate co-monomers and one diol monomer, wherein the two carboxylate co-monomers are furan-2,5-dicarboxylate and terephthalate, and wherein the one diol monomer is selected from the group consisting of isosorbide, isoidide, isomannide, 1,4-phenylene diol, 1,2-dimethylphenylene diol, 1,3-cyclohexanedimethane diol, and 1,4-cyclohexanedimethane diol; and
the 2,5-furandicarboxylate and terephthalate co-polyester comprises from 0.1 mol % to 20 mol % furan-2,5-dicarboxylic acid co-monomer and from 80 mol % to 99.9 mol % terephthalic acid co-monomer.
