A wide range of plastics are used in agriculture, including, polyolefins (polyethylenes (PE), Polypropylene (PP), Ethylene-Vinyl Accetate Copolymer (EVA)) and less frequently, Poly-vinyl chloride (PVC), Polycarbonate (PC) and poly-methyl-methacrylate (PMMA).
The main agricultural films are: geomembrane film, silage film, mulch film and film for covering greenhouses.
Agricultural films encompass mulch, solarization, fumigation barrier and crop protection films made either from polyethylene (PE) or biodegradable materials. They are either slick, with a smooth surface, or embossed with a diamond-shaped pattern on the surface.
Mulch films are used to modify soil temperature, limit weed growth, prevent moisture loss, and improve crop yield as well as precocity. Because of their thickness, use of pigments and their exposure to high solar irradiation, mulch films require proper light and thermal stabilizers with intermediate chemical resistance.
