5 Gallon Mylar® Bags

Heavy-Duty 5-Gallon Mylar Bags for Long-Term Food Storage

Protect your family’s bulk food supply with commercial-grade 5-Gallon Mylar Bags. Specially sized to fit standard 5, 6, and 7-gallon storage buckets and food totes, our heavy-duty foil bags create an impenetrable barrier against light, oxygen, moisture, and pests. When paired with proper oxygen absorbers, 5-gallon Mylar pouches keep dry food staples fresh for up to 25–30 years.

Which 5-Gallon Mylar Bag Do You Need?

We carry a variety of bag styles and thicknesses to match your exact storage goals:

  • 5 Mil Thickness (Standard Protection): Our most popular choice for bulk staples like rice, wheat, oats, and flour. Provides high barrier protection while remaining easy to fold, tuck into buckets, and heat seal.

  • 7 Mil Thickness (Extra Heavy-Duty): Maximum puncture resistance for sharp or rigid foods like uncooked pasta, hard beans, or freeze-dried meals with sharp edges.

  • Open Top Style: Traditional flat Mylar bags designed for fast, permanent heat sealing using a flat iron, household iron, or impulse sealer.

  • Zip Seal Style: Features a heavy-duty reclosable zipper. Heat seal above the zipper for long-term storage, then use the ziplock for convenient access once opened.

Oxygen Absorber Recommendation for 5-Gallon Bags

To ensure an airtight, oxygen-free environment (below 0.1% oxygen level), pair each 5-gallon bag with:

  • 1 x 2000cc Oxygen Absorber (or 4 x 500cc Absorbers)
