Food Prepping

Food prepping is becoming more popular across Australia with people wanting to prepare themselves and their families for possible future food shortages.  Food prepping is also a very convenient, long term food storage option for people living regionally. 

Mylar bags are the most popular storage option for food prepping as the foil layer has an extremely low Oxygen Transmission Rate. 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
  • Food grade 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.
You can add boiling water to these mylar bags to reconstitute meals. Please take precaution as the bag will be hot to touch. It is advised to place your bag in a sturdy container before adding boiling water.

NOTE: ALL Mylar bags MUST be heat-sealed AND include an Oxygen Absorber for proper food storage.  The re-seal top is only for re-sealing food after you open it. Oxygen absorbers are also required.

Each oxygen absorber pack includes an Oxygen Indicator.

*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.

Food Prepping Guide

Oxygen Absorption Required for Common Foods

Oxygen Absorbers for Long Term Food Storage. To ensure adequate oxygen absorption is used 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. Remember is it okay to use MORE absorbers than necessary, if unsure.
