Oxybarrier is a higher end PVC free liner which totally seals off the bottle. This means, what’s in it stays in and nothing comes in or out; leaving the beer fresh for about 3 months longer than a regular PVC free liner. This liner is commonly used for lower rotation, high end beers which are bottled in a near perfect environment. In a nutshell, if you have a good filler and the oxygen is near 0 when the cap goes on, then this liner is the best of the best.
