SOTRAFA,
S.A. can make different
perforation frames:
macroperforation,
multiperforation or
microperforation.
The diameter in the
presentations varies
in terms of the different
uses and applications.
We highlight the following
among others.
MACROPERFORATION
Diameter
of perforations
50 and 80 mm. They
can be in parallel
or in diamond formation.
The objective is
to make the perforations
in the exact place
following a predetermined
plantation frame,
which can be based
on the distance
of the dripping,
optimising of the
distribution of
the plant, etc.
MICROPERFORATION
Diameter
of perforations 10 mm. They
can be in parallel or in
diamond formation. Used
in a great variety of crops
(melon, watermelon, peppers,
etc.). Up to 500 perforations
per square metre.
It
consists of making perforations
of 1 -2 mm throughout all
of the width and length
of the film. This way we
will avoid scorching on
the film. It helps the exchange
of gases between the air
and the ground and we will
continue having the desired
effect against weed growth
(in case of black film).
It is especially indicated
for creeping crops and hydroponics
to help eliminate the drainage
of water on the surface.
