Oxygen scavenging compositions and packaging comprising said compositions

A process for making an article comprising:

• (a) forming a melt by combining the following ingredients in a melt processing zone:
• (i) at least one base polymer comprising a polyester polymer,
• (ii) at least one non-polymeric oxidizable organic component present in an amount of about 0.10 to 10 weight present of the composition and the component comprising at least one compound of the formula E-(L-E)x wherein:
• E is
