Versaperm Vapour Permeability measurement


Hundreds of millions of pounds wasted due to poor packaging

Water vapour is extraordinarily invasive and the wastage it causes has been estimated to cost hundreds of millions of pounds in the UK each year. Properly designed packaging and drug delivery systems, with a suitable seal or permeability, are crucial to extend the life of everything from inhalers to unitary dose blister packs and from cold cures to sterilised plasters.

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, it reduces the potency of drugs, causes chemical change and leads to biodegradation. It can even alter the dose from an inhaler. The Versaperm system can test the permeability of a huge range of products and packages – from blister packs to sterile packaging and from sachets to cough sweet wrappers.

Versaperm also provides a sample permeability testing service.
