Why Choose ShieldPro Bulk 5-Gallon Bags?

Large-scale food preservation requires ultra-reliable materials. Independent lab testing confirms ShieldPro bags outperform competitor retail brands across key metrics:

• Superior Strength: 30% greater puncture resistance and up to 90% higher tensile strength than standard market bags, protecting against sharp foods like dried beans or pasta.

• Total Oxygen Barrier: Seals oxygen levels down below 0.1% when paired with proper absorbers, ensuring your food stays fresh for 25 to 30 years.

• Food Safe & Non-Toxic: 100% FDA-approved multi-layer structure. Free from BPA, PFOA, and PFAS.

Key Wholesale Benefits

• Deep Bulk Savings: Factory-direct case quantities yield the lowest cost-per-bag for preppers, co-ops, and commercial repackagers.

• Versatile Bucket Compatibility: Fits 5-gallon buckets or totes (We recommend totes for space efficiency).

• Easy to Seal: Compatible with impulse sealers, flat irons, or standard household irons (~325°F–375°F).

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.
