Mylar Bags for Food Storage
Food-grade mylar bags provide the ultimate barrier against oxygen, moisture, and light — extending shelf life up to 25-30 years with oxygen absorbers. Cubit manufactures FDA-compliant custom mylar bags for coffee, snacks, spices, freeze-dried foods, grains, and pet food. Full-color printing with food-safe inks starting at 500 units.
Why Mylar Is the Gold Standard for Food Storage
Moisture Barrier
<0.01 g/m²/day
Aluminum layer blocks all moisture transmission, preventing clumping, mold, and spoilage.
Oxygen Barrier
<0.1 cc/m²/day
Multi-layer PET/AL/PE stops oxygen penetration, preventing oxidation and rancidity.
Light Protection
100% UV Block
Opaque metallic barrier blocks UV and visible light, preserving nutrients and freshness.
Shelf Life
25-30 Years
With oxygen absorbers in properly sealed bags, dry foods maintain quality for decades.

Are mylar bags FDA-approved for food contact?
Yes. All Cubit food-grade mylar bags are manufactured with FDA 21 CFR compliant materials. Our PET/Aluminum/PE laminate is safe for direct food contact and is the same barrier film used by major food brands worldwide.
How long do mylar bags keep food fresh?
Properly sealed mylar bags with oxygen absorbers preserve dry foods for 25-30 years. Without oxygen absorbers, standard barrier life is 1-5 years depending on the product. Key factors: bag thickness (5+ mil recommended), seal integrity, and storage temperature.
Do I need oxygen absorbers with mylar bags?
For long-term storage (1+ years), yes. Oxygen absorbers remove residual oxygen after sealing, preventing oxidation and extending shelf life from months to decades. For short-term retail products like coffee or snacks, the mylar barrier alone provides excellent protection.
What thickness mylar bag is best for food storage?
For long-term food storage: 5.0 mil (127 µm) or thicker. For retail snacks and coffee: 3.5 mil (89 µm) is sufficient. For lightweight sachets and samples: 2.5 mil (63 µm). Thicker bags provide stronger puncture resistance and better barrier performance.
Can I get custom printed food-grade mylar bags?
Absolutely. Cubit offers full-color FDA-compliant printing on food-grade mylar bags starting at 500 units. All inks are food-safe, and nutritional label panels can be integrated into your design.
Are mylar bags better than vacuum sealing for food?
For long-term storage, yes. Mylar bags with oxygen absorbers outperform vacuum sealing because the aluminum layer blocks light and provides a superior oxygen barrier. Vacuum bags are transparent and offer no light protection. For maximum food preservation, mylar with O₂ absorbers is the gold standard.
