I have several 3 litre wide mouth jars that I want to use for oaking spirits and long term storage however I believe the seals on these jars are most likely rubber.
To make these jars usable I thought I would create new seals with HDPE sheet that I have found on ebay. (see link)

Question: Is HDPE suitable for this purpose?
