Great mylar bags

Good quality mylar bags, thick enough and well built. A prepper's must.

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.

Product as described. Useful item

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.

For the money you're paying, these are very nice, quality items. There are others that are more sturdy/durable but they cost an arm and a leg. Being a person that must watch every penny I spend, these are a smart use of my money. I will keep buying these for my quart storage needs. The only "con" to them is that the zippers on the bags are always zipped close and there have been times that I've damaged the bags, trying to get them open. I guess one could argue that the zippers being so difficult to open means they are top quality zippers! If you need good quality at a decent price, I'd recommend you try these.

Great product
