Applications - Agricultural
Agricultural mulch films are used all over the
world in order to control the growing conditions
of crops and enhance moisture conditions, and
smooth out variations in temperature and rain
fall during the growing season. These products
are an essential part of the high intensity
agricultural farming required in order to meet
the demands of an increasing population.
With this application the
film is often almost impossible to recover and
where it is, it is heavily soiled. In some
situations it can carry ten times its own weight
of soil, making pulling it from the ground in
one complete piece almost impossible.
In some regions thicker
films are collected and washed off, but this is
rare and very much crop dependant.
It is more likely that they
will be torn up and either land filled or burnt,
neither is a suitable end to this important
Wells Plastics have spent
the last four years in an intensive development
program in the agricultural world looking at a
longer term solution for this problem.
Incorporation of Reverte®
into an Agricultural Mulch film has
the following benefits:
A film can be made so thin
without the intention for it ever to be lifted
from the soil; this allows ultrathin films to be
utilised saving on plastic, costs and resources.
The film will at a
predetermined exposure breakdown rapidly
allowing the crop to be recovered and the
degraded polymer ploughed in. This highly
degraded material is susceptible to biodigestion
and will ultimately biodegrade.
Wells Plastics have
developed a special agricultural film grade
which can be dosed at different levels to
achieve different breakdown kinetics to suit the
This material has been
independently analysed over the last four years
for safety, suitability and of course
The use of a Reverte®
film has many advantages of the use of a
In particular the
weight of the film can be four times greater
than that of a light weight polyethylene film.
The carbon foot print of a
treated film is far more favourable than that of
the hydrobiodegradable solutions currently
The cost is much more
attractive in all terms.
The formulation is
programmed to suit the crop and climate.
