We manufacture covers in coextrusion for greenhouses, which allows the use of additives and an adequate selection of raw materials for each layer, obtaining specialized plastics, with excellent mechanical properties and a better cost-benefit ratio for our customers.
They prevent the passage of insects that feed on plants or are carriers of viruses that reduce the life of the crop and reduce yields and the quality of production.
Tipos de Películas para Invernaderos:
Excellent values of total transmittance with UV additivation for a lifetime of 1, 2 and 3 years.
High transmittance of solar radiation, ultraviolet and short infrared rays.
Excellent mechanical properties
Allows 60 to 70% of the irradiation of the soil and plants to pass.
Proper control of the temperature inside the greenhouse.
The light is diffused uniformly in all directions and levels of the plant not only in the upper part which promotes growth and better development in all directions and a higher quality of fruit.
It promotes better development and growth.
Reduce the greenhouse temperature a little.
There is no blockage of PAR light, as happens with liming.
More uniform development and higher fruit quality.
It is a film with additive, which does not allow the adherence of the powder to its surface, reducing the quantity and quality of the light that passes inside the greenhouse.
They facilitate the washing of the cover since the dirt and dust do not adhere to the film as it happens in other materials.
It is a film with additive, which allows the passage of solar rays and prevents the dissipation of heat during the night keeping inside the greenhouse a sufficiently high temperature to favor the development of the crops.
Due to the nature of the additive, the transparency of the film (light passage) is reduced. They present diffusion of light.
The antifog additives modify the superficial tension of the film propitiating the sliding of the water accumulated on the surface by condensation when the outside temperature drops.
It allows the water that condenses on the inner side of the film, tends to do so in the form of a continuous layer, which prevents dripping and facilitates runoff. It increases the productivity of the crops, since the lower drip reduces fungal diseases and prevents burns due to the magnifying effect of the drops.
This film blocks a certain range of ultraviolet radiation, which is necessary for the orientation of insects. With this film the fungi do not mature and spores do not develop and there is no blackening on the petals of the roses.
Antiblackening: It is designed specifically for flower producers, helps control and eliminates the darkening of the petals.
It consists of the block of a percentage of light transmission with the use of additives and pigments.
Counts With Excellent Properties:
It is the necessary force required to break a movie. It is measured in both directions of the film.
It is the stretch that can support the material before breaking.
Impact force that resists a movie.
It is the necessary force to propagate the tear, once it has been started. It is measured in grams strength.
Ownership of the films is very important as it directly affects the development and productivity of the crop.
It is the amount of total visible light that allows the film to pass into the greenhouse.
The unit of measurement is in percentage. Solar radiation is a very important factor in the precocity, quality and productivity of the plants, so that as much as possible of this.
Recommendations for the installation of Greenhouse Covers:
The structure must be free of rust, wires, sharp or loose parts.
In the contact area of the plastic with the structure, it must have adhesive reflective tape or be covered with light colored water-based paint.
Do not touch the rolls during installation.
Do not drag, hit or drop the rolls abruptly during handling or handling.
Do not install during hotter hours due to the softening of the plastic that causes excessive tension and can cause strong contractions when the temperature decreases.
The tension of the plastic should be adequate to prevent it from being loose and generate friction on the structure causing breakage, and not too high to avoid premature degradation due to stress of the material.
