Planeta Plastic - Polyethylene Transparent Film
Used in greenhousefacilities to cover greenhouses and hotbeds for one season. Infrared absorbents added to the film allow shifting the UV part of the solar radiation spectrum to the visible part. These films have another useful characteristic – they block infrared radiation inside the greenhouse. In greenhouses covered with such film, the temperature is maintained at 3-5 degrees above the ambient temperature during spring frosts and 3-5 degrees below the ambient temperature during the summer heat. The occurring greenhouse effect makes it possible to extend the use of greenhouses without additional heating.
Basic properties of polyethylene transparent film by LLC “Planeta Plastic”:
- flexibility and transparency;
- steam and water resistance;
- retention of heat inside a greenhouse;
- low price.
The film is made of high-density polyethylene by extrusion. Due to the rotation mechanism of the blow head of the extruder, the proportional non-uniform thickness is provided for across the entire width of the film sleeve. Manufactured in the form of sleeves 1,000 to 3,000 mm wide, half-sleeves 400 to 1,500 mm wide, as well as sheets 300 to 1,500 mm wide. The film thickness ranges from 30 to 200 microns.
