A combination of LDPE and HDPE that offers exceptional mechanical properties that make it ideal for its application and resistance in structures with mechanical movement.

  • Advantages include an elevated resistance to chemical products, provided by the largest combination of fabric and laminations options available
  • Formats span a wide range of widths, thicknesses/weights.
  • Optimized material selection allows for the reduction in thicknesses, without sacrificing the resistance of the material, which lead to cost savings.

Covers for tender fruits such as table grapes, cherries, kiwi, etc. Woven poly or LDPE-based materials with special characteristics, such as eyelets, string reinforcements or perforations, that are adapted to the unique structures used to protect valuable fruit crops.

We offer turnkey projects and professional advice to make it easier for the grower to employ protected fruit cultivation. Full control of the process is available to the grower and the end result is protection against adverse weather events, fruit ripening control as well as an increase in productivity and yields.
