Hundreds of millions of pounds wasted due to incorrect packaging

a world leader in water vapour permeability measurement, has introduced
a quick and simple way to test the all-important water vapour
permeability and transmission rate of paper, packaging and coatings.
Water vapour is extraordinarily
invasive and the problems it causes to pharmaceutical, food and
perishable products such as have been estimated to 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 wastage.
The Versaperm WVTR
(Water Vapour Transmission) meter was designed to meet this need.
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
The WVTR 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.
