There are a LOT of places to get Mylar® bags and oxygen absorbers nowadays. So, what sets us apart? It's quite simple, really...our products stand out. And this isn't just a catchy slogan; our bags truly excel, as confirmed by testing. Among all 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 30 years out of your food storage, you should be using the best storage products available.
