Abstract
The invention relates to the use of a structure comprising at least one layer of a polymer (A) comprising: the units (A1) 1 and the units (A2) 2 such that the A2/(A1+A2) molar ratio is between 0 and 30%. The present invention also relates to packagings and hollow bodies, such as pipes, bottles and containers, comprising the above structure.
Claims20
In a method of preventing oxygen from permeating through a barrier film, comprising placing said barrier film in a locus wherein oxygen is present, the improvement comprising employing as said barrier film at least one layer of a polymer (A) comprising repeating units of:
- 9
- wherein the A2/(A1+A2) molar ratio of the units (A1) and (A2) is between 0 and 30%.
An article of manufacture comprising at least one layer of a polymer (A) comprising repeating units of:
- 11
