ABSTRACT:
This relates to a multilayer preform and a container blow molded from such preform wherein both the preform and the container are of a multilayer construction with there being utilized as an oxygen scavanger and oxygen barrier and a blend of either PET/MXD-6 nylon or PET/MXD-6 nylon/Co. In the resultant container, the percentage of MXD-6 nylon will be less than 1% and the container will be directly recyclable. Also, the percentage of MXD-6 nylon in the container will be such that there will be no noticable reduction in the clarity of the container. Also, because PET forms a part of the blend which provides the oxygen scavanger and barrier, the layers in the container will be bonded to one another.
