Greenhouse films contain special combinations of UV-stabilizers and antioxidants protecting them from the harmful effects of UV light and heat for very long periods. All formulations are based on HiTeC's own know-how and experience. Additive concentrates are manufactured in-house to ensure absolute consistency in quality.

Film lifetime is guaranteed for a period of 1-5 seasons (depending on type of film and area of use). In most cases, greenhouse films contain more and more efficient UV-stabilizers than films of other producers, which is one of the reasons why PEP films usually last longer than they are prescribed for.

Due to the increasing use of sulphur and other chemicals in the greenhouses, that neutralize traditional UV-stabilizers and may lead to premature failure of the film, Hitec has developed fully chemical resistant formulations that can be incorporated upon demand in any of its greenhouse film types for additional safety.
