6 Mil | 4 Year | Superior Strength

The Durability and Toughness You Need! Super 4™ is a super clear, super tough, long-life product that provides the best value in a 6-mil, 4-year greenhouse covering film. Super 4™ plastic greenhouse film is also available with 55% white opacity in selected sizes.

  • Outstanding light transmission, haze, and clarity ratings help optimize yield in greenhouse applications.
  • A unique manufacturing process and advanced resin technology provide Super 4 films with superior tear strength.to pr
  • High strength at folds reduces the likelihood of punctures and tears in critical areas.
  • Advanced UV stabilizers maximize physical properties for the rated life of greenhouse film and help protect film from chemical damage.
  • Bee compatibility feature allows more of the UV spectrum to pass through the greenhouse poly film, making it easier for bees to navigate and achieve more efficient pollination than with mechanical means.
Performance Guarantee Super 4™ is guaranteed to withstand 48 months/4 years of UV exposure under normal circumstances.


Effects of Chemicals on Polyethylene Film in the Greenhouse Environment.  Greenhouse film provides long life and dependability. You can further ensure good results by avoiding snags and tears during installation and using a white plastic (non-PVC) batten or adhesive tape to separate the film from the heat of the structural members. Shading or painting the film at the polylock will also reduce failures caused by heat.ad

Using advanced materials and strict quality controls  can assure you that our products offer the exceptional ability to withstand the effects of natural UV radiation and weathering—even in the most severe climates. What is more difficult is protecting the films from the effects of exposure to the man-made elements found in the greenhouse environment.  Even the best quality greenhouse films may be weakened or destroyed by contamination from certain chemicals. To protect your investment in crop and greenhouse covering you should know what chemicals and cultural practices to avoid or modify.  

• Certain chemicals attack the polymer itself. These are usually oil-based solvents in paints and petroleum distillates used as solvents for wood preservatives. Avoid direct contact of any polyethylene film with oil-based paint products or wood preservatives.
• Other products, such as copper bactericide sprays, may catalyze the breakdown of polymers. Minimize direct contact with the plastic greenhouse film when using copper sprays.
• High concentrations of chlorine, commonly used in greenhouses as a disinfectant, will also adversely affect the polymer. Avoid the use of chlorinating solutions or household bleach products. Instead, use one of the commercially available disinfectants such as Greenshield® or Demoss®.
• Chemicals in the greenhouse environment can also affect the HALS stabilizers. Sulfur, halogens (fluorine, bromine, chlorine, etc.) and chemicals containing them, especially pesticides, are very aggressive in deactivating the HALS stabilizers.
• Rose growers using large amounts of sulfur and chlorinatedhydrocarbons (Pentac® is one example) have learned to expect reduced greenhouse film life compared to growers who have less need for regimented pest controls.
• Using foggers and smoke generators also leads to direct contact of the pesticide with the plastic and can shorten film life. Overspray can lead to large volumes of pesticide coming in direct contact with the plastic and should be reduced or avoided. Many pesticides not containing halogens or sulfur are available and should not be harmful to greenhouse films when used as directed.
• Direct contact with PVC pipe, PVC tapes, or lagging made with plasticized PVC can also provide a source of damaging chlorine that can act upon the HALS stabilizer and the polymer itself.
• Whitewashing should be done with products designed for greenhouse film. Other products such as latex house paints may contain fungicide additives. Some of these fungicides contain chlorine or other halogens that reduce the effectiveness of the HALS stabilizer and may shorten film life.
• Sulfur and other chemical contaminants can come from external sources, such as aerial spraying of adjacent vineyards, orchards, or field crops. This is sometimes characterized by degradation of the outside layer of plastic greenhouse film while the inside layer maintains good physical integrity. It is a good idea to know what your neighbors are spraying with and to plan accordingly.
