I work in PET blow molding but I get these 15 gallon HDPE vessels at work for free
I want to turn them into a cheap kind of conical but I'm uncertain about how oxygen proof they are. A friend at work told me that sometimes when they make these they include an additive to the plastic that makes it oxygen proof.
these were originally used for cranberry concentrate - anymore info on this from anyone?
Also I was thinking that even if they are not oxygen proof I could buy bags to use as liners on the outside of the vessel
The plan is to build a stand to put the vessels on and them mount a bulkhead fitting to the bottom to facilitate racking out of them in place
any input on this would be helpful
