Water Vapour Permeability Testing

Water vapour is extraordinarily invasive and can ruin the quality of a beverage in a sachet or container. Although it’s easy to test against liquid water, as a vapour it can pass straight through many packaging materials and seals that are totally impervious to it in its liquid state. Testing for this is a vital step in any new packaging as mistakes can be very expensive in product recalls!

Versaperm Limited, a world leader in water vapour permeability measurement, has introduced a quick and simple way to test this crucial factor for the packaging, films, coatings and containers used for all manner of beverages. It can test both the packaging material itself and the product’s seal.

The Versaperm WVTR (Water Vapour Transmission) meter can cope with multiple samples at a time - often giving a reading in as little as 30 minutes – whereas the conventional gravimetric measurement technique takes several days and is significantly less accurate. The company offers both the equipment and an “overnight” laboratory testing service.

The meter is easy to use and gives a series of digital readouts that can be recorded or simply read off the LCD screen. It needs no re-calibration and requires, at most, minimal training to give results that are accurate to better than one part per million (with some samples a few parts per hundred million). Sensitivities are in the range 0.05 – 3200g/m2/day.

Water vapour is omnipresent, it can reduce the shelf life and quality of powdered beverages, it can cause chemical change and can lead to biodegradation, product recall and waste.
