Mylar Bags

Here is a list of our Mylar Bag sizes and an approximate volume for each bag size allowing for the lost space at the top seal.

When working out how many oxygen absorbers needed in a bag remember to take into account the amount of food/product inside the bag. The space left inside the bag contains the amount of oxygen to be removed. Or you could simply just used an oxygen absorber the size for the total volume of the bag. This way the calculation is easy and it is always better to have a bigger amount of oxygen absorption than needed.

Stand Up Pouch Bag 10cm x 15cm x 5cm= ½ Pint / 0.6 Litres

Stand UP Pouch Bag 15cm x 25cm x 5cm 1 Quart / 1.5 Litres

Stand UP Pouch Bag 20cm x 30cm x 5cm / 2.5 Litres

Stand Up Pouch Bag 25cm x 35cm x 5cm 1 Gallon / 3.5 Litres

Stand UP Pouch Bag 30cm x 40cm x 5cm / 4.8 Litres

We recommend using food grade iron oxide oxygen absorbers also known as deoxidisers inside mylar bags for long term storage.  Iron oxide oxygen absorbers remove oxygen from inside the bag to prevent the growth of aerobic micro organisims, mold, bacteria and fungi prolonging shelf life. Different cc ratings for different sized bags or food types are recommended.

When using oxygen absorbers they will remove 21% of the air inside the bag or container.  This is because the absorbers only remove the oxygen (O2) which is about 21% of air.The general formula for cubic centremetre of oxygen absorbtion required is:

Container volume – food volume = residual air volume

Residual air volume x 0.21 (because air is 21% oxygen) = oxygen absorber size needed

It is okay to exceed the size of oxygen absorber needed and its better to err on the safe side and use more.

Conversions:

1cc = 1ml
1000ml = 1 litre
3.78 litres = 1 gallon

Our Oxygen Absorbers are made by Dorency. They contain Iron Powder and have an oxygen absorbtion capacity 3 times more than the cc rating.  Here is a chart with some details:
