Description

Wallaby Oxygen Absorbers are the essential companion for Mylar bags, ensuring your stored food stays fresh for decades. Available in 300cc, 400cc, and 500cc sizes, they are crafted from food-grade, BPA-free materials and carefully packaged in sets of ten to preserve effectiveness until use. Unlike loose bulk packs that lose potency once opened, our portioned packaging means you only use what you need, when you need it.

Each packet works by removing residual oxygen inside sealed Mylar bags, the primary culprit behind mold growth, oxidation, insect activity, and nutrient loss. When combined with low-moisture foods like rice, beans, wheat, oats, powdered Milk, or freeze-dried meals, Wallaby Oxygen Absorbers can help extend shelf life up to 30 years.

Perfect for emergency preparedness, camping trips, or everyday pantry organization, these absorbers provide reliable performance across a wide range of bag sizes:

  • 300cc works best for quarts and pints

  • 400 to 500cc fits 1-gallon flat or gusset bags

Pair them with our Mylar storage pouches, label your bags for easy rotation, and have peace of mind that your food supply is secured for years.

FAQs

What are oxygen absorbers used for?

Oxygen absorbers are used to eliminate oxygen inside sealed Mylar bags, preventing spoilage, mold growth, pests, and nutrient loss

How many oxygen absorbers do I need per bag?

As a rule, 400cc is recommended for every gallon of storage. For smaller bags, 300cc works well, while 500cc provides extra protection.

Can I use oxygen absorbers in containers other than Mylar bags?

Yes. They work in cans, mason jars, and other airtight containers.

Can I use multiple oxygen absorbers in one bag?

Yes, using more than one is safe. It’s better to overuse than underuse since they only react to oxygen and do not cause harm to food if overused.

Do I need to vacuum seal Mylar bags with absorbers?

No. Simply pressing out the air before heat-sealing is enough; the absorber removes residual oxygen inside.

How long do oxygen absorbers last once opened?

They start working immediately. Use them within 10 to 15 minutes or keep unused ones sealed in a mason jar or vacuum bag.

Can I use oxygen absorbers with foods high in oil or moisture?

They work best with dry goods under 10% moisture. Avoid foods like jerky, nuts, or brown rice for long-term storage.

Are oxygen absorbers reusable?

No. Once activated, they cannot be reused. Always use fresh absorbers for new storage.

How do I know if an oxygen absorber is still active?

Active absorbers feel soft and pliable. Once spent, they become hard.

Do oxygen absorbers affect the taste of food?

No. They are safe, food-grade, and only remove oxygen. They do not alter taste or texture.
What Makes Wallaby Mylar Different

Wallaby Mylar stands out for its superior thickness, durability, and reliability. Our bags are made with premium, food-grade materials that provide an airtight barrier against moisture, light, and oxygen. Plus, the user-friendly design—like zip-seal closures and stand-up gussets—makes storing everything from pantry staples to bulk ingredients easier and more secure.

How to Use
  1. Fill the Mylar bag with your chosen food (opt for dry goods with 10% or lower moisture content).
  2. Add the recommended number of oxygen absorbers (around 400cc / gallon of storage, more never hurts).
  3. Push out as much air from the bag as possible, but you do not need to vacuum the air out.
  4. Seal using a heat sealer, hair straightener, or clothing iron and be sure to heat seal just above the zipper seal if there is one.
  5. Label with the contents and include the date it was filled for easy reference and pantry rotation.
Usage Ideas
  1. Fill Mylar bag with low-moisture dry foods (rice, beans, grains, flour, etc.).
  2. Drop in the correct size oxygen absorber (400cc per gallon is standard).
  3. Push out excess air, but no need for vacuum sealing.
  4. Seal the bag with a heat sealer, iron, or hair straightener.
  5. Label contents and storage date for easy rotation.
