AMPACET Latest Developments and Innovative Solutions for Plasticulture
Like every week, the latest issue of the macplasonline (issue no. 384 published on July 11th) a publication of AMAPLAST of Italy has several interesting articles and news, both in Italian and English languages. This time the editorial team picked up part of an article that is more close to the needs of Iran in these days and of course might be interesting for many others in the world.
AMPACET Latest Developments and Innovative Solutions for Agricultural Films
Plasticulture is a growing market with increasing requirements towards higher crops quality and yields to meet the needs of growing population. In order to help satisfy the market needs, Ampacet has developed a range of masterbatches for greenhouse and tunnel applications including Agristab 372, Agroclear Range, Heatscreen 34 and Thermic 337.
To protect crops from pests and diseases farmers usually apply fumigation pest control. Sulfur evaporators are one of the most commonly-used methods to fumigate greenhouses. But the use of sulfur fumigation leads to a loss of UV stabilizing properties of the greenhouse film. Photo-oxidation of sulfur deposited on the greenhouse film surface can yield acidic species, deactivating light stabilizers (Hindered Amine Light Stabilizer – HALS) and resulting in early degradation of the film and shortening greenhouse shelf life.
Typical greenhouse film containing conventional nor HALS stabilizers is designed for maximum 3,000 ppm sulfur content and three years, or four seasons, of effectiveness, while the market tends to require greenhouses with longer life-spans and higher pesticide usage, to withstand up to 5,000 ppm sulfur for a duration of more than three years.
Innovative Agristab additive technology fulfills new market requirements for a multi-season greenhouse with highly intensive pesticide usage, beyond the Spanish Committee for Plastics and Agriculture (Cepla) recommendations. Agristab 372 provides greenhouse film with outstanding resistance to pesticides, allowing usage of up to 5,000 ppm sulfur for a greenhouse that can last for more than three years. Agristab 372 also enables use of lower-gauge greenhouse films in structures and the ability to target typical pesticide usage levels of, for example, 1,500 to 3,000 ppm with lower amounts of stabilization. Agristab 372 does not affect the colour of the greenhouse film and offers excellent light transmission and optimized crop yield.
Another typical problem faced in greenhouses and low tunnels is linked to fogging phenomena.
Being aware of these reality, Ampacet has broadened its Agroclear range and introduced its new Agroclear 752 for 1 to 2 seasons greenhouses, low tunnels and early harvest crop protection films. Ampacet Agroclear 752 allows, at very low addition rates, to provide outstanding and consistent antifog properties to protection films used in agriculture and horticulture fields. It maintains an excellent film transparency, avoids problems linked to fog formation (light transmission reduction and plant damages), optimizes plant growth and supports crop yield.
