Measuring the vapour permeability of laminates

The vapour (vapor) permeability of laminates is critical to the performance of the finished material.

Laminates are extremely widely used to combine the properties of two or more material layers - for example the vapour permeability of a metal foils with the strength of a polymer and the handling or finishing characteristics of a third material.

Our equipment can measure the permeability of most laminates - from building boards through to unitary dose drug packages, modified atmosphere food packaging, petrol cans and far beyond. It can measure both water vapour permeability and/ or the permeability with respect to virtually any other gas, including Oxygen, Helium, Carbon Dioxide (CO₂) and hydrocarbons.
