Plenty of options that will require you to think about what you are doing. Personally, I would select the 7-mil mylar bags recommended by @sablebrush52.
There is Mylar, and there is Chinese Mylaresque material.
it's Myrar*So, the Myral is not as good as Mylar?
I have some Sammy G flakes that I must not have completely removed the air from and they have puffed out like balloons after 3-4 years. Seals are still totally fine but I have some jars from the same batch that I’ll have to A-B.If I leave some air in the heat-sealed mylar bag, will the tobacco age like it does in a jar?
