50pcs 1 Quart Mylar Bags for Food Storage, 7"x10" 10 Mil Stand-Up Zipper Pouches Resealable and Heat Sealable for Long Term Food Storage(7"x10", Extra Thick)

These bags are high quality and stand up well, making them easy to fill with freeze dried food. They close easily and are nice and thick bags.

Overall, I'm satisfied with the quality of the product, but note a few details. The bag is spec'd as 5 mil thickness , and actually measures 4.5 mils....10% thinner. I'm satisfied that the 4.5 mil will work for my use, but if this -10% is a make-or-break deal for you, be advised. The zip-lock does leak air, and does not offer a hermetically sealed bag. Inflate the bag, and gently squeeze the sides and you will note that air does escape through the zip-lock. The side seams and the gusset on my test will not leak air, so these are quality joints. So these bags are suitable for short-term storage, but for long-term you will need to heat seal above the zip with an impulse sealer, defeating the use of the zip-lock. Or move onto a vacuum sealer. No evidence of pin-holes in the gusset seams. The seams are well formed on all the bags I inspected. Others have reported that the zip is difficult to open. It is stiff, and does require some effort. However, the stiffness insures that it will not open accidently in a backpack, and enables air-tight short-term storage. Totally satisfied, and would buy these bags again.

Great product

I use these to vacumn pack prepper items using a food saver. Anyone who wants to do it, can google how to make it work. I have vacumn packed Flour, Yeast, Almonds, Macaroni, Dehydrated veggies, Powdered milk etc etc. Holds a good seal if you do your part and seal well. Most items I can expect a shelf life of 25 + years. Much cheaper than buying "survival food packs", and very prudent since we are facing global food shortages this year. Ukraine and Russia produce over 30% of the worlds wheat. Flour, bread, pasta is all made from wheat. I expect these items to be scarce and also very high priced in the coming months. Buy cheap stack it deep, and these will help ensure it doesn't go bad. Pro's: Easy to vacumn seal ( using the right technique which you can google) Strong and puncture resistant. O2 Absorbers were good, work well They hold a seal well Shipping was fast (3 days) Can be re-used to seal something else if careful opening. Yes they will seal again just a little lower than where you originally sealed them. Con's : To vacumn seal you have to cut the zip lock off, because it closes when you press the food saver shut. Minor inconvenience. We all have scissors. When you want to open, must cut open. If you use the opening tabs, the bag tears diagonally sometimes ruining the bag. I want to reuse these so cutting them up is a must.

Like, just what I wanted for emergency storage

I love these bags. They are great quality to keep my freeze dried food fresh. I like the size of them and the fact that they can stand up. They also reseal and continue to keep food fresh after opening.

Materials: I've been using mylar bags for quite sometime, this one is made food-grade materials which is safe durable, and Tasteless. It is thicker than what I use before which is about 10 mil. It an internal layer of aluminum foil which is puncture resistance, and prevents light and air permeation to keep the food safe and stays longer. It has a resealable so you can used it repeatedly. You can store it standing on you the storage shelf. Easy to Use: You can seal it with hot iron,. You can store grains, rice, dried fruits etc. Value of money: With the amount of money you can save by storing food this is cost effective.

These are my go-to bags for all my freeze drying needs. Excellent weight, not thin like some of the others I had tried. They do a wonderful job. I also love the zipper close so I can seal them prior to heat sealing the bags. That provides me a lot less stress and more working time to get them in the heat sealer. I do all my work alone and before I had to do one bag at a time so as to not waste oxygen absorbers. This allows me to do all my bags at once and seal the oxygen absorbers in and then go back and do all the heat sealing in one go. It definitely makes my work much more efficient and saves me time. Would highly recommend.
