Quart (8" x 12") AirTight Seal-Top Mylar Bags – 300cc High-Capacity Oxygen Absorbers - Long-Term Food Storage - Genuine Standard Thickness -Air Tight - Heat Sealable - Food Grade - Rounded Corners - Free Guide - Pack of 100

Overall this is a "Good" product... I was hoping they were a little thicker but are fine for my freeze dride foods. Therefore the 4 not five stars.As for ease of use... this is a bottom loading bag. The "ziplock" end is sealed and you must load and seal right away.The O2 absorbers are great and work like always.PackFresh sells a great product and is my "GOTO" for my packaging needs when it comes to my freeze dried foods....!!

My first set of such supplies so I cannot attest to durability over time. They do seem like they will last has so far been working as described. I dont know if I missed it in the description or should have known in the lack of description.....the mylar bags are more see-through than I expected and that was my only disappoint. I would buy again and try for more opaque set.

The oxygen absorbers were hard, rendering them useless. The mylar bags are pretty transparent....not sure if it will affect the food items inside, but I'm not going to chance it.Will definitely do more research and not buy these again.

Dehydrate all food for back packing. These allow you to control salt, sugar and other non-nutritive supplements for your own. Takes time and special equipment, but worth in end. These are what you need.

Roomy, prefer the smaller pocket ones, but these are really nice too. They have the best products and the best price. They also have a great customer service. If you are looking for the best way to protect your stash you can't go wrong with PackFreshUSA!!!

Great product! I use these bags to prep meals for backpacking/hiking trips! These are a MUST for any backpacker!!

Am buying more! They work.

The product is working fine. Large enough to store many one to two servings. I am able to seal the bags with an old vacuum food saver that does pull air.
