100pcs Mylar Bags 1 QUART - Thick 9.4 Mil - 7"x10" Airtight Vacuum Sealing Sealable Mylar Bags for Long Term Food Storage, Odor Free Heat Resistant - Light and Moisture Proof Fresh Saver Packs (100)

We freeze dry food and these bags are extremely thick and well made. Have purchased them multiple times.

I always get these. I think the price is reasonable and the size works really well for me. The quality and thickness is very good. I have an excellent sealer and generally never have a problem with the seal.

Works like a charm

Great bags good construction. Will definitely reorder

Good bags, might order again. Maybe. A few of the bags’ ziplock tore off the inside of the bags when I opened them to use. If you don’t utilize the ziplock function, no worries, but for those of us who do use the ziplock with or without a heat seal, it’s a bummer.

best size for freeze drying.

Very thick, and I didn't realize that I could get by with much smaller ones, but I'll save these for other prep projects. Happy with them nonetheless.

I use them for packaging freeze-dried foods. They are a good thickness and protect the food well. They seal well with a crimp sealer. The gusset allows for extra capacity, and standing upright during the packaging process. I have ordered and reordered and will continue to do so as long as they are available. I have gone through just over 500 of these bags so far and have never run into any issues concerning the integrity of the seal. Added O2 absorbers and crimp sealed, not a single failure. Just received 200 more and will update this if necessary, but the recent delivery looks equal to those before it.
