Mylar Bags create airtight, lightproof protection for long-term food storage and sensitive packaging. Heat-sealable, tear-resistant, and durable, they effectively block oxygen and moisture, preserving food, herbs, and dried goods. Commonly used in bulk packaging, emergency food storage, and industrial applications, Mylar bags ensure product freshness and extended shelf life. Kraft Bags offer an eco-friendly, biodegradable alternative, making them ideal for sustainable packaging solutions.

Mylar Bags provide a cost-effective, durable, and airtight solution for long-term food preservation. Made from polyethylene terephthalate (PET), Mylar is a strong, flexible, and non-porous material that acts as a barrier against oxygen, humidity, and light, significantly extending the shelf life of stored items.

Why Use Mylar Bags?

  • High tensile strength – Resistant to punctures and tearing
  • Lightweight & flexible – Conforms to contents and collapses when oxygen is removed
  • Sealable & airtight – Prevents moisture and light from degrading contents
  • Ideal for food storage – Extends the freshness of grains, dried foods, powdered milk, herbs, spices, and more

How to Use Mylar Bags for Maximum Shelf Life

  • Choose the right size and thickness (ranging from 89µ to 178µ)
  • Add oxygen absorbers before sealing to prevent spoilage
  • Seal the bag using heat (iron, hair straightener, or Mylar bag sealer)
  • Label the contents and packing date for easy identification

For a reliable and effective food storage solution, Mylar Bags are the perfect choice.

What are Stand Up Pouches used for?

Can I see the product inside Stand Up Pouches?

Many Stand Up Pouches have a transparent window so the contents are visible without opening the package.

Do I need to line my container with Kraft paper?

Lots of containers are lined with kraft paper primarily for reasons of hygiene or to simply isolate the cargo from direct contact with the container walls. The liner will act as a kind of sponge, catching and absorbing any droplets of water and then re-evaporating the moisture into the air. If liner is used without Absorpoles it could contribute to a kind of pumping effect, drawing moisture out of the cargo. When used together with Absorpoles the liner will act as a buffer in extreme conditions, and will prevent any container rain from reaching the cargo. Much the same can be said for so-called dew cloths.

Can I reuse Mylar Bags?

Yes, if opened carefully along the tear notch. They can be resealed, but long-term storage performance is best with new bags.

What thickness of Mylar Bag should I choose?

Thicker bags (110 microns and above) offer better puncture resistance and extended shelf life.

Mylar Bag 30*40cm + 500cc Oxygen Absorber

This was my second purchase with Protection Experts Australia. Super happy with products and delivery. Exactly what I hoped it would be. I have no hesitation recommending them, or purchasing again.
HOWEVER - On arrival, packaging was smashed, which is no reflection on the supplier, but on Australia Post. Contents of package were intact, so no biggie. Have spoken to Post Office, but what can a local business do about the attitude of the larger organisation.

Stand Up Pouch 16*23cm + 100cc Oxygen Absorber

Just as described.. perfect size for storing smaller portions for travel, single serves etc.. I I could make one suggestion it would be to separate the ox absorbers into 2 or 4 groups as once open you have to separate out and reseal asap if not doing mass amounts. lesson learnt for next time.. be prepared when opening them. Super impressed with them though.. thank you

Second purchase from ProEx and excellent as usual. Products are great and post always quick. Smaller bags like these are perfect for coffee, quick oats etc in a much more manageable size if storing them term ie SHTF situ.

If you're looking for serious food storage then I recommend these Mylar bags. They're extremely strong and great for storing my foods extending their shelf life that need protection from oxygen, light, and you need oxygen absorbers ( https://pro-ex.com.au/products/desiccants-preservation/oxygen-absorber/oxygen-absorber-100cc/ )to get the best result for your food storage.
