Packaging a gas

  1. I'm looking to create a very small expandable package to be filled with a very small amount of a volatile material at a low temperature. I'm looking to fill this package somewhere around 0.2mL of this material (propane, butane, etc) so that when exposed to room temperature, the package expands to a larger size, 3mL, and works like a propellant to push against a piston. Does anyone know of a technology, similar to converters or food packaging, that could fill small packages of a foil or a metallized mylar pouch, etc that can either expand due to exposure to room temperature or "unfold" due to exposure to room temperature and contain the gas from leaking?

    Just a guess: bubble wrap producers should have experience with something like that.
