ABSTRACT:
A multilayer biaxially oriented heatset article and method of making forming a preform comprising an outer layer and an inner layer of poly(ethylene terephthalate) (PET), an intermediate layer of olefin-vinyl alcohol copolymer, a layer of adhesive laminating the olefin-vinyl alcohol copolymer layer and the outer layer and a layer of adhesive laminating the inner olefin-vinyl alcohol copolymer layer and the inner layer. The preform is then heated to orientation temperature and blown against a heatset hot mold to produce an article such as a container that has high barrier properties, improved thermal stability, i.e., capable of being hot filled at elevated temperatures, have layer uniformity, good interlayer adhesion., good transparency and is light in weight.
