ABSTRACT
An enumeration and critical analysis of the many worldwide developments and proposals of the past twenty years f@
oxygen barrier plastic package materials for food products. Introduced with great publicity, numerous oxygen barrier
technologies have either disappeared or have evolved elsewhere. The rationales for their initiation and apparent
reasons for their current positions are reviewed.

A typical rubber with low gas permeation which might suit your application is butyl rubber (IIR), but it is of course not, as i expect all other polymers, really impermeable.
To reach (near) impermeability a metal might be used.
I hope this is usefull to you

@ Michael Päch: this is of course correct and was more meant for sake of clarity concerning the unlikeliness to find an impermeable polymer
All polymers used for food packaging are (or must be) non-toxic and of good barrier properties for oxygen. Polyethyleneterephthalate (PET), for example
Thank you everyone! I think I will use one of the following: PVA, PVDC or PAN. The thing is about O2 diffusion rate through the material and it needs to be extremely low in my case.
@ Dimitri Likhatchev: PET is actually an example of a polymer with not sufficient barrier properties - that is why beer is not very stable in PET bottles.
Piotr Pander what was your final decision? I have the same problem right now, and I am just wondering what was your solution?
Kindly,
Bega
