Dear, the thickness of this smell proof bags is about 7.2 mil/0.18 mm, hope it helps.

Can these handle boiling water in order to rehydrate food?

You wouldn’t want to use these bags for that purpose.

Can you get through TSA with it?

TSA depends on the state not this product. If in a legal state (med or rec) they dont look for it. They just confiscate it if they come across it. If your bag is good and they dont need to pull it they let you go. TSA specializes in boom booms and pew pews and the like. In an illegal state this is not always the case. In these states they may look for it and consequences may be more than just confiscated. I recommend carrying a little febreeze bottle or similar to repeated spray yourself and your bag through checkpoints to keep smells low. No perfume or cologne. Too overpowering and dead giveaway as it sits ontop of dank.

Is there a larger size of this bag?

Yes, sure, the larger mylar bag size is 5.5x7.8 inches and 5.9 x 8.7 inches.

Great package for small items

Why did you pick this product vs others?: Great little mylar bags for a good price. I use them for packaging seeds in the little clamshell style containers. Perfect size for my usages.

Unfortunately the size……

The size is the whole envelope not the actual pouch. I couldn’t find a use for them and discarded them.
