COAT OF MANY COLOURS & PROBLEMS
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
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!
