HIGH TECHNOLOGY COVERS

HUELVASOL® 7 layers

Huelvasol® is a diffused light thermal film made with a mixture of EVA, special polymers and mineral charges that thanks to its exceptional mechanical resistance and resistance to aging is widely used even at thin thicknesses with excellent results of both durability and resistance to the elements. Huelvasol® ensures great light and temperature conditions ideal especially for growing strawberries.

Huelvasol® is born from the experience of many years in the Huelva area of southern Spain and is currently considered by the farmers who have used it the best cover for strawberry production greenhouses. In its standard version Huelvasol® is produced at a thickness of 90 microns for the duration of a minimal agronomic campaign thus offering farmers extremely cheap and technologically very advanced coverage.

Thanks to Huelvasol® the kilograms of cover used per hectare have been greatly reduced with huge benefits for farmers and benefits for the environment. Huelvasol® is produced in 90 µm for a season.

N.B. I dati riportati nella presente tabella sono riferiti al film prima del suo utilizzo. I tempi di vita previsti, possono essere negativamente influenzati da una non corretta posa in opera e/o dall'utilizzo di fitofarmaci e pesticidi contenenti alogeni e/o metalli pesanti (quali ad esempio zolfo, cloro, bromo, rame, zinco, ferro, etc). A questo proposito vi invitiamo a leggere attentamente le Avvertenze per un corretto impiego in agricoltura dei film in LDPE-EVA-LLDPE-POLIAMMIDE .
Attention. The data are referred to the film tested before the use. The lifetime expected can be negatively affected by an uncorrect cladding operation and/or use of pesticides containing halogen -based compounds and/or heavy metals(as sulphur, chlorine, bromine, copper, zinc, iron, etc). In this respect we advise you to carefully read our instructions for a correct use of LDPE-EVA-LLDPE-POLIAMMIDE films.
The values shown in the previous table refer to the film in the duration class specified in it. The film is available in duration classes A, B, C, D and E. For more information, contact our offices.
