Abstract
The present invention relates to polymer structures such as thermoplastic films having improved aroma barrier properties and methods for making the polymeric structures, which may be in the form of a resealable container. Aroma barrier is improved by incorporating a barrier layer of polymeric material including at least about 10 mole percent of polymerized cyclo-olefin moieties.
