Abstract

See full text

This disclosure provide new multilayer polyester (particularly PET) containers that have improved gas barrier properties over conventional monolayer PET containers. In particular, a 2,5-furandicarboxylate polyester (for example, poly(ethylene furan-2,5-dicarboxylate) (PEF)) barrier layer that has superior gas barrier and mechanical properties relative to PET, that is “sandwiched” between two PET layers, has been found to achieve a significantly higher barrier against gas permeation relative to conventional monolayer PET container of the same size and shape. Associated preforms, methods, and compositions are disclosed.
