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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good durable bags.
