Yeah, that's for something like 100 square inches of 1 mil (.001") film at 100F and 75% RH. What about a bottle like used for fuel? .050" thick? cooler and less humidity? Less than .01g/day?

The fact is plastic bottles leak gasses at various rates. The industry has gotten very good at what they do so the permeation is very low these days. Take for instance Loctite bottles. Anaerobic sealants set up in the absence of oxygen. LDPE is pretty good at keeping water from passing, but not at all good a keeping oxygen from passing. It makes the perfect bottle for Loctite and it doesn't set up in the bottle before you can use it.

CA cures in the presence of water. Guess what it's packed in? HDPE bottles.

I don't worry about the type jug glow fuel comes in.
