what does greenhouse film do? What is its use

  • what does greenhouse film do? A greenhouse is a space to protect and control plants so that they grow without damage or hindrance. Greenhouse film is a type of plastic cover that protects greenhouse plants. These films are produced from the combination of light, heavy, linear polyethylene and various additives to create multiple effects for covering vegetables, plants, and fruits.Continue with plastickar.

    The type of additives used in the production and the thickness of the film is different based on the durability required by the customer, as well as the place of use and the type of soil and pesticides .

    Plastic greenhouse films are produced from high-quality raw materials and additives to increase the durability and efficiency of the product.

    Greenhouse films

    Chemists invest in the research and development of new additives to improve the performance of agricultural films.

    Since greenhouse films are a means to grow crops by overcoming adverse weather conditions, they support agriculture. Greenhouse films use sunlight radiation to bet internal microclimate parameters and additives in plastic films to optimize crop production.

    Multi-layered degradable films are considered for coverage and use in removing or covering a frame to achieve a greenhouse effect.

    Polyolefin film can be used by having a degradable component where ultraviolet and thermal stimuli activate degradation. Degradable polyamine film changes color by changing the selected layer according to the season and geographical location of the covered area.

    In agriculture, crop protection films or mulches are widely used. In conventional methods, a thin plastic film is placed on cultivated soil that has already been seeded, seeded, or transplanted at the same time as soil cultivation.

    With standard plastic coating techniques, It is possible to cultivate the soil and apply the plastic film simultaneously with the existing machinery. Such a technique allows earlier germination of seeds. It protects seedlings from late-season frosts, which do not inhibit the growth of seedlings in the early stages of germination. In addition, this film can be used in conventional greenhouse structures or as a mulch film.

    Characteristics of greenhouse films

    The greenhouse film should be able to maintain at least 50% of the initial tensile strength in the film after the desired lifetime.

    The greenhouse film should refer to the areas most exposed to the energy of the sun’s radiation.

    The lifespan of the greenhouse film depends on the type of polymer chosen.

    In greenhouse film, the use of additives mostly depends on the processing conditions during production.

    Greenhouse film is affected by environmental conditions and exposure to sunlight, and its effect is in the final use.

    Features of a greenhouse film

    Improve product quality

    Strong and durable

    Available in regular and customized types for use in specific areas

    Durability based on customer needs (1 to 5 years)

    Preparation for installation

    To prepare, remove any thin and sharp objects that may cause damage during installation or use. The metal frame of the greenhouse must be galvanized class C and free from corrosion. Wooden greenhouse frames must be completely smooth and uniform.

    The metal mold in contact with the greenhouse film must be painted with white water-based paint. All painted surfaces must be dehydrated before the coating is installed. If clamps are used, the clamps must be wholly coated with anti-rust and paint.

    To prevent damage caused by heat and rust, use white or plastic wires, and in both cases, make sure that the plastic used in the wire is not PVC.

    The metal frame should be based on the AFNOR NF EN 13031-1 standard. 1. To be designed.

    Installation of a greenhouse film

    The film should preferably be installed in the morning or afternoon in clear weather (10 to 20 degrees Celsius).

    The film should be stretched long enough to prevent any sudden movement. Avoid over-stretching the film.

    The film should be placed 25 cm from the greenhouse frame.

    In the cross-shaped parts of the metal cladding, the film should be placed against the direction of the wind. The tunnel must have proper ventilation to prevent excessive heat.

    To avoid jerks and vibrations, the film should be tightened regularly.

    During storage, the film should be kept in its original packaging at a medium temperature, away from sunlight, moisture, and chemicals.

    Recommended practices for greenhouse cover films

    • Only layers of the film can be sufficiently resistant to wind stress or impact. Therefore, it is recommended to use double-walled pillow films with 0.2-0.3 inches of water pressure measured with a pressure gauge. And outside air should be used for inflation due to the lower percentage of humidity in cold weather. Blown air must be directed diagonally vertically or almost vertically inside the film.
    • Color should not be applied to the film. Which colors are recommended to create shade, and are suitable combinations to be made and used for greenhouse shade? And if the base of the beams is painted, the paint must be completely dry before placing the film and contacting it. And in this regard, it is recommended to use latex paint instead of solvent-based paints and paint the film on top of the wood or metal support beam with a white color combination that lowers the temperature of the film and helps preserve the film.
    • Soap and detergents must not remain in the film. Suppose the film is washed with soap or detergent. In that case, the film should be washed well and carefully with water immediately afterward. Should soaps containing pine oil or other solvents be used?
    • Clips or nails must secure the film. Otherwise, it is not guaranteed. In this regard, it is recommended that aluminum lock channels are used. These films should be wrapped around a separate piece or placed between two pieces of parts, and we should make sure that it is tightly tied enough to the greenhouse. The use of an aluminum system is a winner against the use of strips and objects.
