Greenhouses provide a controlled, sheltered building for plants to grow unhindered. Greenhouse film is a type of plastic covering used to shelter the plants inside of a greenhouse from the larger world outside.
YOU CAN REQUEST CUSTOMIZED PLASTIC FILM TO MEET YOUR AGRICULTURAL NEEDS.
Polyethylene sheet for covering crops, greenhouse covers, agricultural plastic, poly-film and greenhouse plastic.
- Strong & durable
- Co-extruded plastic PE greenhouse covers for fruits, vegetables and flower crops
- Regular or thermal film tailored to special applications and climatic condition
Facilitate the removal of dust, soil and dirt stuck on the outer greenhouse surface with rain or a simple wash
Prevent decrease in the amount of light transmitted through the greenhouse cover
ANTI-FOG (ANTI-DRIP OR ANTI-CONDENSATE)
Reduce surface tension of condensing water vapor, so that condensation trickles down the plastic wall of the greenhouse film, preventing:
- Damage and disease caused by water dripping blooms and leaves, reducing the need for pesticides
- Also, scorching of plant leaves caused by sunlight on water drops
- Up to 30% reduction in light availability caused by water droplets on greenhouse film surface, resulting in earlier harvest and higher yield
Earlier harvest, higher yield and better quality and uniformity of crops. Resulting in:
- Reduced Evapo-transpiration, which increases sugar and taste quality of produce
- Substantial energy savings when heating greenhouses
- Minimize temperature fluctuation:
o During the day, slightly decreases temperature inside greenhouses by blocking near infrared radiation (nir; 750- 1400 nms) outside thermal greenhouses
o During the night, increases temperature inside greenhouses, by creating a barrier to far infrared radiation (fir; 3,000-14,000 nms) reflected by the soil
Optimize light diffusion inside the greenhouse cover without decreasing light transmission: prevent shadow spots and reduce high energetic sun rays resulting in:
- Better environment for plant growth during hot season
- Better crop quality and higher productivity
Ethyl Vinyl Acetate (EVA) Co-polymer
- In addition to the infrared additive, benefit with the EVA additive from:
Increase in transparency due to a reduction in crystalline patterns
Enhancement in the film mechanical properties
Increase in heat resistance on metallic greenhouse structure
- LIGHT DIFFUSION Break sun radiation into a multitude of rays, optimizing the even spread of light within greenhouses, which:
Increases efficiency of photosynthesis when covered areas of self-shading and trailing plants receive light
Decreases potential for sunburn on blooms and leaves
- UV Stabilizer
Inhibit degradation of PE polymers in greenhouse film without blocking UV radiation
Contribute, along with photo synthetically active radiation (par), to the organoleptic properties of vegetables, fruits and flowers
Furthermore, stimulate natural bee, bumblebee and other insect pollination
Block UV sun rays (up to 380 nm):
- Causing insects to lose visual ability inside greenhouses, preventing viral, fungal diseases and crop damage caused by white flies, aphids, red spiders, leaf miners, thrips and other insects
- As well as, resulting in substantial decrease in dependence on and use of agricultural chemicals, contributing to integrated pest management (IPM) programs
Using of disease control films should not be in greenhouses requiring insect pollination
Anti-Petal Blackening of Red Roses Block far infrared and UV light (up to 380 nm), preventing rose petals from blackening in strong sunlight.
Manual to Use
Preparing for the Laying:
- Prepare the structure by removing any sharp object that could damage the film during installation or use. Metal greenhouse frame should be galvanized class “C”, exempt from corrosion. Wooden greenhouse frame must be planed and sandpapered.
- Paint metal greenhouse frames in touch with the film with white water-based paint. Be certain that all painted surfaces are thoroughly dry before installing the coverings. Also, in case using clips, they must be rust-proof and painted.
- To avoid overheating and rust damage, use white plasticized wires or plastic wires. In both cases, the plastic used should not be PVC based.
- In addition to, metallic structure should be designed according to “AFNOR NF EN 13031-1”.
Laying the Film:
- The film should be laid during soft weather (15 °C to 25 °C), preferably mornings or afternoons.
- Films should be stretchable to avoiding any untimely movement against the structures. Avoid over stretching.
- The film should be dugable in at 25 cm from the greenhouse frame
- When cross cladding, overlapping of the films must be in the opposite way of the dominant wind direction. Also, the tunnel must always be ventilated to prevent the film from overheating.
- The film should be regularly re-tightened in order to avoid fluttering and water bags.
- When stored, film should be kept in its original packaging in a room at a moderate temperature away from direct sunlight, humidity and chemicals.
