100PCS Mushroom Planting Kit - 8"5"20" Thickened Growing Bags, 6 Mil Thick Durable, Tear Resistant, 0.2 Micron Porosity Resistant High Pressure Spawning Bags

I’ve never used any of the more expensive bags out there on the market, but these bags function perfectly. No contamination, bags vacuum seal in my pressure canner, no melted or exploded bags. I elevate the rack on the bottom of my 23 quart Presto With canning rings, pressure sterilize for 2 1/2 hours with 2 quarts of water, I do not surround the bags with any sort of protection against the walls of the counter, and I have zero issues. Will be buying these again and again.

The media could not be loaded. I love the thickness of the bag. They have a rigid quality to the plastic, making working with the gusset a breeze and keeping the upper bag upright, giving fruits plenty of air.Also, good price on 100.

Good thickness and size for 3-5 lb blocks.

Gets the job done!! Nice size spacious for many applications hold up in autoclave thick plasticWorth the money spent.

While most have held up after being autoclaved at 15psi for 3 hours, some of the bags have split where they wrinkled during cook, making sealing difficult. The plastic, after cook, feels brittle and weak, making me uncertain about thr structural integrity of a whole block being jostled around in any way.Bought for the price and need, have decided to go with another option instead going forth.They did the job, but not particularly well.

Good for the price but the centers do not seal well for some reason and I use a high quality sealer.

I like this product compared to others cause it can withstand the heat of steam sterilization over a long duration. Also heat sealing without sticking to the sealer itself. So 10/10

As described. Thickness is accurate. Filter held fine from pressure cooking. Price just as good if not better than ali or temu. Ordering more now.
