100pcs Quart Mylar Bags with 500cc Oxygen Absorbers-112 Labels & 10 MIL Thick Stand-Up Reusable Airtight Smell Proof Resealable Bags with 5 Clips - Food Storage Large Mylar Bags

Great for long term storage..

Oh, I love these mylar bags! When I went to pick them up from my front porch, they were heavy! These bags are super sturdy, and very airtight! You get 2 sheets of 56 labels each, 100 oxygen absorber squares, and 5 clips. I was wondering what the clips were for. They're for sealing the bags if you're doing a lot of them at a time, the clips can help you seal the zip top without running your fingers across the bags so many times.There are cutouts on both sides of the bag above the zipper for if you're heat sealing the bag, you can just rip apart the top without needing to use scissors.These are great bags, at a great price for each bag! I'm using them to put homemade treats in and then heat sealing them to give as gifts.

I got these to put sensitive devices and foods in. The Mylar bags seem important to use in combination. I am also putting a desiccant packet inside. I plan on getting a heat sealer because that will be more air-tight than just the zipper. A heat sealer also allows resealing the bags once cut open.Bags are heavy weight and have good zipper seals. I measured 0.117mm thickness (4.6 MIL). Clips help when closing lots of bags. Oxygen packets can go into a Mylar bag once open, to keep fresh.
