ABSTRACT:
A container wall of stretched plastic material has high oxygen barrier properties by incorporating an activating metal into the plastic material. The plastic material is PET in admixture with a polyamide and the metal is either added to the mixture or contained in one or both of the polymers. The material is stretched and aged to produce the container wall with the high oxygen barrier properties. The metal is preferably a transition metal and can be derived from a salt, such as a halide or acetate.
