A film for agriculture known as polyolefin is created mostly from olefin resins like polyethylene. The product is marketed as an agricultural material under the names “No-PO” or “No-Poly.” Polyvinyl chloride film, also referred to as “agricultural vinyl chloride,” used to be the standard, but with to improvements in its solubility, strength, and workability, it has now replaced it, and the usage of polyolefin film has increased dramatically.
For small tunnel culture and growing medium-sized rice seedlings, polyolefin film is frequently used as a film. General agricultural polypropylene, special agricultural polypropylene, and silver polypropylene are the three categories into which poly films can be separated depending on the use.
The Global agricultural polyolefin film market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
As cover materials for protecting crops in greenhouses and similar environments, conventional polymeric film such as polyethylene, copolymers of ethylene, and other polyolefins has been widely employed. Despite the fact that traditional materials have several benefits like low cost and lightweight.
A polymeric composition that is particularly well suited for agricultural application contains at least 80% polyolefin and 1% to 15% by weight of a basic metallic sulphate addition.
By using standard methods that are well-known in the field, all of the aforementioned additives can be simply introduced into the polyolefin. To obtain a good dispersion of the additives, one advised approach is to employ high shear equipment, such as Werner Pfleiderer type continuous blenders or Banbury type internal blenders.
Once the mixture has been created, it can be transformed into agricultural film using any process currently in use, including calendrical moulding, casting, and, preferably, tubular film. As a result, the harmful impact on the plants is significantly diminished. They are generally opaque to ultraviolet radiation.
They are great light diffusers because they lessen the shadows that the plants’ leaves and the greenhouse’s support structure cast inside. It is essential to obtain the greenhouse effect for them to be highly transparent to visible light and short-wave infrared radiation. Their mechanical strength is nearly identical to that of films produced of polyolefins without fillers that are typically used for this application.
