Best greenhouse plastic

With the development of polymer production technology, elastic greenhouse plastic films have been created. The physical and chemical characteristics of these materials enabled the development of new types of tunnels and greenhouses in addition to the known types of structures. I would like to highlight some factors you can consider in order to narrow down your research for the best greenhouse plastic. But first, let’s have a look at the most popular options on the market.

Things to consider when looking for the best greenhouse plastic:

The type and technical characteristics of the plastic film determine the shape and size of the object, that is, the type and quality of the supporting structure.

  • A good plastic film for covering greenhouses should allow the visible part of the spectrum to be at least 80%, the ultraviolet spectrum at least 20%, and the infrared at most 10%.
  • It must be hydrophilic, so after moistening on the inside, the condensed water vapor drains, not drips.
  • The most important functional features that greenhouse plastic films should have are:
  • elasticity and good resistance to splitting, stretching, and perforation (drilling),
  • transparency for the Sun’s rays, especially in the visible spectrum, and especially for the rays in SFA (photosynthetic activity spectrum),
  • the ability to retain heat in a greenhouse overnight,
  • the long shelf life of mechanical characteristics and transparency.

Today, greenhouses use polymers formed of ethylene and vinyl acetate (EVA, EVAFLEX), and new types of multi-layer photoselective films, smooth or rough surfaces. Antiviral and photoselective materials improve the growing conditions of vegetables in a protected area.

The choice of materials of the best properties allows the expansion of production in different climatic zones and the optimal use of natural conditions. Besides the properties associated with light and heat, the contemporary foil is also hydrophilic stabilized, photoselective, and long-lasting.

In high-temperature areas, perforated foils with openings of 20 to 40 mm are used for the protected area, which makes up 2-10% of the entire surface of the foil. These openings allow for good regulation of temperature and humidity, which reduces the need for foil removal.

The IR filter film absorbs or reflects radiation within the range of 7 to 15 m. It is the wavelength of heat waves that the earth emits into the surrounding space. This preserves the heat that accumulated during the day, which is especially significant during cold nights because it reduces the risk of plants freezing and the cost of reheating.

The films have additives to create diffusion light, which increases the intensity of photosynthesis. Diffusion light especially needs in lush plants that inevitably self-shade. The proportion of diffusing light, depending on the type and purpose of the film, ranges from 15% to 60%.

Greenhouse plastic films can also be used to cover the interior of greenhouses and greenhouses with panels. This usually does in winter, especially when cold winds blow. The same material places low complementary tunnels inside the semi-high and high tunnels, which in the case of frost prevents damage to the plants.

When choosing greenhouse plastic films, keep in mind the climatic characteristics of your area, the plants grow, and the solutions that will regulate the climatic factors inside the greenhouse. Practical experience shows that the use of modern plastic films has a great advantage in the agricultural market, and the production itself is simpler and cheaper than the use of ordinary one-year films.

Polyethylene film (PE)

This film is milky white, impermeable to water, partially permeable to CO2 and O2. It does not maintain the ice, so it remains elastic. This greenhouse plastic film transmits 80-90% of the visible part of the spectrum (0.39-0.78 m) and 70-75% of the ultraviolet (0.28-0.38 m), which is favorable for plant growth and development. Polyethylene film transmits 80-85% of the infrared rays, which partially, especially during the night, reduces the heat in the enclosed space.

Today, hydrophilic films, as well as polyethylene (LDPE) films, are most commonly used.

New types of foil have a shelf life of over 5 years.

Polyvinyl chloride film (PVC)

This greenhouse plastic film is similar in appearance to cellophane and characterized by good light transmission. It transmits 90% of the visible part of the spectrum and 80% of the ultraviolet part of the spectrum and does not send the infrared part of the spectrum (10%), which is favorable for the protected area because it cools slower. The life span of this greenhouse plastic film is 2-3 years.
