Versaperm Vapour Permeability measurement

Preventing premature spoiling would save £100Ms

The major factor in the premature spoiling of food is water vapour. Unlike liquid water it is difficult to stop as it seeps through virtually everything – from flexible plastic packaging through to rigid containers and seals.

Some foods demand it is kept out to prevent spoiling, some demand that it is kept in to prevent drying out. The balance is crucial and many packaging materials and ingredients simply don’t perform as expected as they react to water vapour entirely differently to the way they react to water. Over £100M is wasted each year in the UK alone.

The answer lies in proper testing of the permeability of water vapour of packaging and ingredients, and this has become easy due to an overnight testing service from world technology leader Versaperm.

Versaperm, which designs, manufactures and markets its own measurement equipment, can test the permeability and transmission rates of almost all 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.

Results are accurate to better than one part per million (with some samples accurate to 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.

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.
