does the bag seal while it is in the pressure cooker?

No, the folded over edges will stick together but easily peel apart. You will need to use a sealer after final addition.

How thick are the bags themselves, meaning how thick is the polypropylene sheeting? 6mm, 5mm, 4mm, 3mm?

Thank you for your question. Our Mushroom Growing Bags have an exceptional strength/thickness ratio due to the polymer molecular structure with a 4.8mil thickness.

What polymer are the bags made of ?

Thanks for your question. By design, these mushroom growing bags are polypropylene because of its higher melting point and overall durability/strength.
