FRESH APPROACH TO BEVERAGE PACKAGING
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
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
