There are numerous options available for purchasing Mylar bags and oxygen absorbers. So, why do we say "just better bags?" What sets us apart? It's quite simple, really...our products stand out. And it isn't just a catchy slogan; our bags truly excel, as confirmed by testing. Among all of our retail competitors, we earned the highest rankings for both bags and oxygen absorbers. And it's not just a slight edge. Our 7 mil bags demonstrated 30% better puncture strength compared to Top Mylar, Harvest Right, and Wallaby's 7 or 7.5 mil bags. In terms of tensile and burst strength, we outperformed Packfresh, Wallaby, and Harvest Right by nearly 90%. See for yourself: 

If you are only storing a few years, you’ll probably be OK using almost any Mylar bag. But longer than that? Do you want to rely on a company that intentionally uses the best materials, even if it costs a few pennies more, or one that doesn’t? If you’re one of those looking for 20 or 30 years out of your food storage, we believe you should be using the best storage products available.
