Agricultural films

Anti-Fog

Anti-Drip

(AF)

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.

• The need for pesticides
• Scorching of plant leaves caused by sunlight on water drops
• Reduction in light availability caused by water droplets on greenhouse film surface, resulting in earlier harvest and higher yield

Infra-Red

(IR) 

This additive helps the absorption of infrared radiation and reduces the temperature loss at night.

Some features of this additive include:

• Protection against freeze and low temperature
• Significant energy savings
• Earlier harvest, higher yield and better quality and uniformity of crops
• Reduced evapotranspiration, which maintains taste and product quality

Reduces internal temperature during the day by blocking the near infrared rays (NIR) entering the greenhouse, and prevents

temperature loss during the night by creating a barrier to the far infrared radiation (FIR) leaving the greenhouse.

By adding EVA copolymer, the greenhouse film will benefit from the following advantages:

• Increase in transparency due to a reduction in crystalline patterns.
• Enhancement in mechanical and thermal properties of the film.
• Improvement in film flexibility and durability.
• Increase the film heat resistance on metallic

greenhouse structure (frame).

Light Diffusion

(LD)

Breaks sun radiation into a multitude of rays, optimizing the even spread of light within the greenhouses, therefore:

• Increases efficiency of photosynthesis
• Decreases phototropism
• Decreases potential sunburn of blooms and Leaves
• Decreases the plants self-shading

This material is the most widely used additive in agriculture films.

UV stabilizers are added to protect different polymers against UV radiation. Therefore, this additive increases the lifetime of the film:

• Protection of greenhouse films up to 5 years against the sunlight and atmospheric destructive elements
• Stimulate the pollination of insects and bees

Based on the atmospheric conditions, geographical environment, required lifetime and the greenhouse film thickness, specific type and amount of UV additive will be used.

This additive blocks 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.
• Substantial decrease in using agricultural pesticides.

It should be noted that disease control films should not be used in greenhouses requiring insect pollination.
