BIORETE® AIR PLUS insect screen

Arrigoni developed the new line of insect netting BIORETE® AIR PLUS. This new range allows to improve microclimate in protected environment agriculture and offer insect netting with maximum efficiency in the exclusion of most harmful insects, including the very small Thrips (thripidae).

The anti-insect BIORETE® AIR PLUS nets therefore offer 5 important advantages:

  1. Reduced hole size and efficiency in the exclusion of insects as shown in the following video
  2. More holes per square meter for the same hole size, thanks to ARLENE HT® yarn even thinner and with higher tenacity. As a consequence, greater porosity and increase in the passage of air into the greenhouse;
  3. Increased air flow from the outside to the inside of greenhouses improves microclimate, for lower temperatures and more comfortable humidity conditions for plants;
  4. BIORETE® insect netting reduces pesticides needs. At the same time, the ideal microclimate and the improved connection of plants with the external environment ensure a more abundant and above all healthier crop thanks to healthier and stronger plants;
  5. Finally, the use of a greater number of wefts made from ARLENE HT® means a more structured, stable and uniform netting.

“The anti-insect netting BIORETE® AIR PLUS range is a truly innovative product: their weight per square meter is significantly lower than the corresponding products of the competition – explains Paolo Arrigoni, C.E.O. of the group. Instinctively buyers often entrust the heaviest product, but in this case commonsense is totally misleading!”.

“As with racing cars, for example, very lightweight materials with exceptional performance give the vehicle a very high resistance to stress. By reporting the example to our industry, the production of an even thinner yarn with very high tenacity has allowed us to reduce weight and improve the textile structure of the anti-insect net to obtain better performance with many advantages”.

Paolo Arrigoni in the Quality Control Department

“In the specific case of agricultural nettings – the manager continues – use of poor polymers, lack of a modern Quality Control Laboratory or the processing with obsolete machinery force competitors to extrude thicker yarns. On the other hand, the same resistance can be achieved with thinner yarns, produced with first-choice polymers, with a perfect formulation and with state-of-the-art machinery, as happens in Arrigoni with the ARLENE HT® monofilament“.

Comparison between a fabric of Arrigoni (fuchsia line) and a competing product (blue line) to the tensile test: the resistance values are lower in the competing product.

If we consider an anti-insect netting with hole dimensions, for example, of 0.27 x 0.79: for the same area, the use of ARLENE HT® – a resistant and even thinner monofilament – allows an increase in the passage of the air (permeability) higher than the corresponding increase in porosity.

The graph below shows just how a flow of air through the net (fuchsia line) decreases as the thickness grows, much faster than the empty area of the net can decrease. In particular, we note how, for monofilament sizes greater than 0.23 mm, the air flow is even lower than what the intuition would lead us to believe considering only the free surface decrease.

This table summarizes the comparison between Arrigoni fabrics and the competition:


This explains how the exceptional quality of raw materials, research, constant quality control and the use of very modern equipment make it possible to produce lighter but better performing fabrics. At the same time, this guarantee long life for your insect screen and a truly intelligent investment.
