1. Sensitivity of your product to moisture or gas : higher sensitivity your product with, higher gage foil might be the better way to go.
2. Risk and Cost you can undertake: if higher risk and lower cost you can afford, then lower gage foil.
3. Time that your product won't be used : Normally, longer timer, thicker gage foil.
