• Exceptional Quality: Our bags have rounded corners to protect your other stored items from puncture or damage. The strong Mylar film has a burst strength of over 140 psi, equivalent to the weight of 5 cinder blocks per square inch. These bags are strong, durable, and easily sealed with a vacuum-sealer, iron, or hair-straightening iron. Durable Long-term Storage: 7 Mil mylar bags provide a substantial increase in puncture protection, improved durability, and greatly increase long-term oxygen and moisture resistance. Superior oxygen barrier provides over 100 years of protection when used with packfreshusa oxygen absorbers. Low Oxygen Transmission Rate: Mylar bag films provide three layers of protection and offer an extremely low oxygen transmission rate (otr) due to its thick foil laminate layer. This safeguards your food against the elements for long-term preservation. Oxygen Indicator: Each package of oxygen absorbers will include one oxygen indicator. This will be pink if the package is sealed correctly. The color of the indicator may vary from bright pink to a reddish hue when the package is sealed, indicating that there is no oxygen in the package and the absorbers are good. Once the package is opened and exposed, the indicator will turn blue.
