My sister found nice plastic bins at Big Lots for much cheaper than elsewhere. Her daughter worked as a marketer for a disaster reclamation company and she swore by Rubbermaid. I have never put it to the test thankfully but she said that that brand was the only one to give any protection in the event of a fire. The Rubbermaid would no longer be usable but the contents would be protected. She won't use any other brand. This is hearsay, untested information but my niece is sharp as a tack otherwise, LOL!
