Premium 7 MIL Food Grade Mylar Zip Lock Bags XXL 18.9 Litres by Pack Fresh USA

  • Free of BPA and other toxins
  • 100% Unconditional Satisfaction Guarantee
  • Long-term Food Storage Guide included
  • Thickness is 0.18mm Very Strong!
  • Zip Lock on the bottom of bag*

* Why is the Zip Lock on the bottom?

This is the way commercial product packaging is made. First, you don’t want to have to heat-seal in a narrow area next to the reseal top. Second, the result is much cleaner and easier to open and reseal.


How to Use Pack Fresh USA XXL Bags: There is a reason the bottom end of these XXL Mylar Bags are cut open. The zip-locked top of the bag is sealed to ensure the bag is kept sealed for extra protection. 


  • Place XXL Mylar Bag in a bucket with the zip-locked sealed top facing the bottom of the bucket
  • Start filling the Mylar bag with food through the cut-open end of mylar bag
  • Place oxygen absorber/s in the bag
  • Vacuum seal the open end of the bag
  • When ready to use, tear open top and open zip lock

Mylar Bags 7 MIL in XX Large

Mylar films have extremely low Oxygen Transmission Rates due to the foil layer. The thickness of the film overall is not as important as the thickness and quality of this metalisation when it comes to long-term food storage. This is because oxygen cannot penetrate metal. And strength? Even one square inch of this Mylar film can support the weight of two and a half cinder blocks!
  • Extreme oxygen and moisture barrier
  • Foodgrade FDA approved
  • Bags Free of BPA and other toxins
  • Long Term Food Storage
  • Unlike most other brands in Australia these are MADE IN THE USA!
  • Provides well over 25 years of protection from oxidation, mould, and bugs*
  • Zip Lock for Easy Resealing

*Based on the Oxygen Transmission Rate of this Mylar, heat-sealed as instructed with correct Oxygen Absorbers.

NOTE: ALL Mylar bags MUST be heat-sealed for food storage. A reseal top is only for resealing food after you open it.Oxygen absorbers are also required and are available HERE.

Each oxygen absorber pack includes an Oxygen Indicator. Read about Oxygen Absorber Indicators and Myths & Misconceptions of Mylar Bags and Oxygen Absorbers and How to Re-Seal Mylar Bags for more information.

*Mylar Bag must be filled completely. Food types can be deceiving and may contain far more air than you thought therefore it is okay and a great idea to use more absorbing power than necessary. Flour can be 50% air! Pastas can be 75% air! A larger capacity Oxygen Absorber will help account for this. If there was a tiny leak in the seal, a larger absorber will continue to absorb oxygen for many years.
Other Information
Oxygen Absorption Required for Common Foods

Oxygen Absorbers for Long Term Food Storage. To ensure adequate oxygen absorption for long term preservation of food Survival Supplies Australia recommends mylar bags should be filled completely & food packed tightly. There is nothing wrong with using more oxygen absorbers than necessary. If you are unsure of the quantity of oxygen absorbers needed, always go with a higher quantity. Oxygen Absorbers from PackFreshUSA will absorb 180% to 300% of their rating to have a substantial buffer of safety.

Note: like flour and powdered mixes consist of very fine particles, they can contain a surprising amount of air. Be aware that 300cc oxygen absorption quantity per 3.8 litres isn’t enough for food types like pasta.

Easy to seal

by Ralph -

Placed bag in bucket, filled with rice, partially sealed with a hair straightener, dropped in the oxygen absorbent and finished the seal. Easily done. Make sure you label and date.
