How many oxygen absorbers will I need for a 23×32cm Mylar Bag?

The number of oxygen absorbers needed for a 23×32cm Mylar Bag depends on the
void volume
of your package: • The volume of the sealed package • The volume occupied by the food product. The calculation isolates the packaging void (sealed package volume minus food weight) multiplied by 20% — as air is approximately 20% oxygen.
