Has anyone tried this?
I am pretty sure PVC is food safe (since we get our drinking water through it) and I don't think air will leech through it. Cap one end with a regular cap and the other end with a screw on cap. Seems like you could store A LOT of food and it would be cheaper than buckets and mylar. Any thoughts? |

Quoted:
That is a very unique idea. . Not sure about the gas permeability of PVC though either. PVC is around 5-6 ish/mm where Mylar gets .001-.0006/mm. Its better than HDPE where its around 50-150/mm, but mylar for the cost is unbeatable. ETA 10-12" PVC with mylar liners burried in the yard would be pretty damn hard to beat long term. |

It has been done.
Some people have put a chunk of dry ice in the bottom as a cheater oxygen purge. The less bright of those people sealed up the PVC before the dry ice melted - creating bombs that propelled PVC shrapnel across the room. (At least one guy went to the ER over that.) |

Seriously, though, did it work for long time storage? (obviously not the one that exploded) |

From what I have found PVC is still oxygen permeable but much much less than HDPE and more moiture resistant than HDPE but still permeable. I did find that Nylon was a great gas and moisture barrier however.
I still think the main issue is cost, PVC is not that cheap considering buckets are free... |
