Versaperm Vapour Permeability measurement



Handling, Coating, Printing & Re-Pulping

Papers and boards often need a finishing – and it is the coating that is largely responsible for their handling, printing, physical characteristics and re-puplability. The single most important factor in this is the way the coating deals with common-or-garden water vapour!

Versaperm Limited, a world technology leader in water vapour permeability measurement, has introduced a quick and simple way to test the permeability and transmission rate of paper, packaging and coatings. It can cope with several samples at a time and can give a reading in as little as 30 minutes – whereas the conventional gravimetric measurement technique takes several days and is significantly less accurate.

The WVTR / MVTR 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.

A wide range of variations is available, depending on the specific application, but both single and multi-sample systems and a variety of chambers are available for testing samples the size of a thimble up to a pallet load and beyond.

As well as manufacturing the instruments, Versaperm also offers a water vapour permeability laboratory service for companies that need to test samples on an irregular basis.

Water vapour is extraordinarily invasive and the problems it causes cost hundreds of millions of pounds in the UK each year. A simple programme of testing at the design and packaging stage is often all that is needed to eliminate this waste!
