Versaperm Vapour Permeability measurement


Hundreds of millions of pounds wasted due to packaging

Water vapour is extraordinarily invasive and the food wastage it causes has been estimated to cost hundreds of millions of pounds in the UK each year. Properly designed packaging using materials with a suitable permeability can substantially extend product life, prevent products from drying-out or over-hydrating, and reduce waste.

Versaperm Limited, a world leader in water vapour permeability measurement, has introduced a quick and simple way to test this all-important water vapour permeability and transmission rates for most types of packaging, films, coatings and containers.

The Versaperm WVTR (Water Vapour Transmission) meter can cope with several samples at a time - often give a reading in as little as 30 minutes – whereas the conventional gravimetric measurement technique takes several days and is significantly less accurate.

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, degrades products, causes sogginess, boosts biodegradation and reduces shelf-life. In other cases, its loss dries products out, causing viscosity, flavour and aesthetic problems. It can even move through a product, for example pastry gaining moisture from the baked contents. The Versaperm system can test the permeability of a huge range of products and packages – from plastic and paper to pastry and from sugar coatings to foil and pizzas.

The company also provides a sample permeability testing service.
