HOW TO GET TESTY WITH US
Anti-sogginess testing for the paper, packaging & coatings industry

Water vapour permeability technology experts Versaperm are offering a fast and economical testing service to determine the often critical permeability of both paper and coatings. Water vapour can, for example cause paper to jam in a printer, ink to go off incorrectly - or it can substantially affect the life of product in coated containers. Pharmaceutical and food packaging is particularly susceptible.

Versaperm can test the permeability of paper, films and foils, coatings as well as, pill and blister packs. The company has substantial technical experience in the area and is always interested in the challenge of measuring new materials, coatings and systems.

The company uses its own-developed WVTR (Water Vapour Transmission) equipment, which can produce accurate and reliable results to better than one part per million - sometimes in the parts per hundreds of million range. With some materials these results can be achieved in as little as 30 minutes, but even with hard to measure foils, results can normally be turned around in a day. Sensitivities are in the range 0.05 - 3200gm/m2/day.

The service is considerably faster and more accurate than using conventional gravimetric techniques that can take days or even weeks. It can also provide measurements of the equilibrium relative humidity (ERH) of substances that might otherwise be decomposed by normal water content measuring techniques.

As well as standard testing on products such as papers, films and coatings, Versaperm has the facility to test unusual or hard to measure objects such dry coatings, pharmaceutical packaging, small bottles, small industrial objects as building materials, bottles, large industrial objects, foils, laminates and once, even a pizza!
