PackFreshUSA: Quart (8″ x 12″) AirTight Seal-Top Mylar Bags – 300cc High-Capacity Oxygen Absorbers – Long-Term Food Storage – Heavy Duty 5 Mil Thick (Per Side) – Resealable – Heat Sealable – Food

Our bags have rounded corners to protect your other stored items from puncture or damage. The strong Mylar film has a burst strength of 70 psi, equivalent to the weight of 2.5 cinder blocks per square inch. These bags are strong, durable, and easily seal with a vacuum-sealer, iron, or hair-straightening iron.
New “Bottom-Filling” bags are tamper evident and easier to seal. Other brands require you to seal in a narrow area next to the seal top. This makes for an easy heat-seal, and the result is cleaner and much easier to open and reseal. You will appreciate the convenience when it comes time to open. Easily seal with vacuum-sealer, iron, or a hair-straightening iron.
5 Mil mylar bags provide puncture protection, durability, and increase long-term oxygen and moisture resistance. Superior oxygen barrier provides over 100 years of protection.
Mylar bag films provide three layers of protection and offer an low oxygen transmission rate (otr) due to its thick foil laminate layer. This safeguards your food against the elements for long-term preservation.
Oxygen absorbers, surpassing vacuum sealing in oxygen removal, can prolong shelf life. Ideal for various storage containers like mylar bags, vacuum bags, and mason jars.
Each oxygen absorber package includes an oxygen indicator. The indicator, pink when properly sealed, may display varying shades from bright pink to reddish when sealed correctly, signifying the absence of oxygen. Once opened, the indicator transitions to blue.
