Permeability of packs is checked

They can measure the vapour permeability with respect to gases, including water vapour, oxygen, nitrogen, argon, carbon dioxide along with other gas combinations. The meters enable not only the vapour permeability of the materials themselves to be assessed, but also, that of finished, packaged, products, which are rarely the same.

Measuring the permeability traditionally took weeks for a single sample, but with the Versaperm equipment it is said to be achieved in as little as 30 minutes for many films and vapours.

The results are usually accurate to better than one part per million. With some samples, accuracy can be measured in parts per billion. Versaperm’s new and extended sensor range can also be used to measure vapour permeability with almost any common gas or vapour. The instruments have an automated computerised control and can handle several films or finished products at a time.
