Thanks for that JM. I often wondered about this and seems to confirm my thinking....

Plastic buckets and oxygen absorbers
While plastic buckets are much thicker (70 to 90 mil) than plastic laminated pouches, they are still plastic (polyethylene).  Oxygen will eventually be transmitted through the bucket.  Depending upon the thickness and seam stability of the bucket, the general rule would indicate a 2 to 5 year barrier viability life.  This means that in this period of time, the atmosphere in the bucket will equalize with the atmosphere outside the bucket.  Plastic bucket seams are susceptible to the ?pulling effect? mentioned above and can cause oxygen seepage into the container.  Also, depending upon the environment, plastic buckets will eventually absorb moisture and odors.
