We understand that Protection Experts Australia customers should feel confident they are receiving the best quality products. The unopened 500cc Oxygen Absorber bag might feel hard, but that is due to the vacuum seal as they are all clumped together. Once the bag is opened, the sachets will separate and should feel like the container sand/granules. All our 500cc Oxygen Absorbers are packaged with a quality check, called the ‘eye’. The indicating eye is packaged with the 500cc Oxygen Absorbers and will appear pink, showing that the package is sealed and oxygen-free. Should the eye appear purple, this indicates that oxygen has penetrated the packaging through possibly a puncture or poor seal and the 500cc Oxygen Absorbers have been compromised. In this instance, we ask that you contact our office immediately so that the problem can be rectified.

Store 500cc Oxygen Absorbers at room temperature (5°C to 30°C), away from direct sunlight. They should be stored in their sealed package or a glass jar with a gasketed lid. Select the smallest glass jar possible to minimise the oxygen the absorbers will remove from the jar. 500cc Oxygen Absorbers in a well-sealed container will cause the lid to pop down. The shelf life of a 500cc Oxygen Absorber is up to 18 months.

How quickly 500cc Oxygen Absorbers remove oxygen from the atmosphere will depend on the conditions. In dryer climates, it may take up to a week for 500cc Oxygen Absorbers to fully activate. Warmer, humid climates however accelerate the process and may take only 48 hours for the same result.

500cc Oxygen Absorbers trap oxygen. Given that air comprises 20% oxygen and 80% nitrogen, the absorber will only be removing the 20% of the atmosphere that is oxygen. The volume of nitrogen remaining will mean your bag will not deflate to the extent of the bag becoming hard or rigid.

Both these methods are used to remove the oxygen content from a package. Vacuum packaging achieves this by sucking out all air and then sealing the package. Nitrogen flushing forces the heavier nitrogen gas into packaging, pushing out the oxygen content. In both instances, some oxygen remains. It is estimated that when these methods are used there can be 2–3% of oxygen remaining. 500cc Oxygen Absorbers can then be used to capture the residual oxygen present.

500cc Oxygen Absorbers more rapidly capture oxygen at room temperature. Under normal room conditions (20°C), packages will be oxygen-free within 24 hours. At a temperature of 6°C, packages will be oxygen-free within 48 hours. In 0°C to 4°C conditions, packages will be oxygen-free within 72 hours. Given the content moisture levels can differ widely, we suggest customers test for their own unique circumstances.

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.

Mylar Bags are suitable for conditions up to -30°C but have not been tested in ultra frozen conditions up to -80°C

Mylar Bags are designed for long-term storage of dry goods such as grains, pasta, coffee, herbs, powdered foods, and dried fruits. They are also used to protect sensitive non-food items like documents and electronics from oxygen, light, and moisture damage.

Yes. When heat-sealed, Mylar Bags create an airtight, moisture-resistant, and lightproof barrier, preserving product freshness and quality for extended periods.

For long-term storage of dry goods, oxygen absorbers are highly recommended. They remove oxygen from the sealed environment, preventing mould, bacteria, and oxidation.

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