Ultra-Duty 7 Mil Stand-Up Zip Seal Mylar Bags (5" x 8" x 3") – 50 Count

When it comes to protecting your long-term food supply, thickness equals peace of mind. Our premium 7 Mil per side (14 Mil total) stand-up Mylar bags offer the ultimate barrier protection against light, moisture, and oxygen. At 7 Mil, these bags are highly puncture-resistant, making them ideal for storing foods with sharp edges like dehydrated foods, pasta, dried beans, and grains.

With a convenient 1-pint capacity and a sturdy 3-inch bottom gusset, these bags stand upright on their own, allowing for easy, hands-free filling and neat pantry storage. Sold in a convenient 50-count pack.

Why Choose 7 Mil Thickness?

• Maximum Puncture Resistance: No more worrying about dehydrated food corners or sharp grains piercing your seal. 7 Mil provides maximum durability.
• Long-Term Shelf Life: Thicker foil laminate means a near-zero Oxygen Transmission Rate (OTR), keeping your food fresh for up to 25+ years when paired with the right oxygen absorber.
• Extreme Light & Moisture Block: Total opacity blocks out 100% of light and humidity, preventing food degradation.

Key Product Features:

• Resealable Zip Lock: Great for keeping food fresh after opening, or for daily-use storage. (Note: For long-term storage, always heat-seal the top header above the zipper).
• 3" Round-Bottom Gusset: Expandable base allows the bag to stand up vertically for beautiful display and easy filling.
• Food-Grade & BPA-Free: Safe, non-toxic, and FDA-approved material for direct contact with food.
• Easy Heat-Sealing: Seal easily using a standard impulse sealer, flat iron, or household hair straightener.

Perfect For Storing:

• Dehydrated and freeze-dried foods
• Powdered milk, protein powders, and baking ingredients
• Coffee beans, loose-leaf teas, and herbs
• Garden seeds, emergency medicine, and small survival gear

Sizing Tip: This 1-pint (5" x 8" x 3") bag pairs perfectly with a 50cc or 100cc oxygen absorber for optimal preservation.

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.
