POLYDAK CAST

Mulch

Ginegar’s mulch films are advanced multi-layer mulch films that are manufactured using two methods – multi-layer blow film co-extrusion and cast (flat die) extrusion. Offering UV protection, these films are available either embossed (cast) or smooth (blown) and in a wide range of thicknesses and widths according to specific growers’ needs, specifications and crops. 

The cast production method involves embossing while the material is hot,
thereby changing the surface of the sheeting and endowing it with greater
flexibility, softness and strength. This allows better adherence of the sheeting
to the ground surface and is particularly suitable for crops grown on
raised beds. We manufacture our agricultural cover films using our new five-layer co-extrusion technology. This enables us to process raw materials that guarantee the highest level of mechanical strength and flexibility, and compatibility with all mechanical testing standards.

Solarization Films

Due to environmental regulations such as the restriction of use of methyl bromide (since 2005) and the lack of effective alternatives, the use of solarization for soil sterilization (often combined with chemical treatment such as methane sodium for soil disinfestation) has become more and more popular in both organic and conventional agriculture.

Ginegar’s solarization films take advantage of heat from the sun that is trapped under the clear plastic films to control weed germination and prevent harmful fungi, bacteria and some nematodes. These films are usually used in summer and work best in regions with hot and sunny weather for 4-8 consecutive weeks with daytime temperatures of above 80° F (27° C). Note that this method is less effective in coastal climates with summer fog and in windy regions.

Ginegar’s solarization films use an anti-drip additive to improve the total light transmission, maintain soil temperature and contribute to soil sterilization. The following tables show the results of a comparison between standard solarization films without an anti-drip additive and Ginegar’s solarization films with an anti-drip additive.
