Using the Big Gurley®, the air permeability of packaging materials can be measured and assessed. Continuous quality monitoring of bag material is important during bag manufacturing. To do this, special information on the porosity and air escape properties of the bag components are necessary. By adding loose material in the measurement chamber, it is possible to determine air permeability changes of product-sprinkled bag materials.
