## Questions & Answers

**Q: does the bag seal while it is in the pressure cooker?**
A: No, the folded over edges will stick together but easily peel apart. You will need to use a sealer after final addition.

**Q: How thick are the bags themselves, meaning how thick is the polypropylene sheeting? 6mm, 5mm, 4mm, 3mm?**
A: 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.

**Q: What polymer are the bags made of ?**
A: Thanks for your question. By design, these mushroom growing bags are polypropylene because of its higher melting point and overall durability/strength.
