Agricultural films

The usage of plastics in the agriculture industry is growing every day. PlasticKar is one of the leading manufacturers of agriculture films in Iran, which has been producing and supplying a wide range of Agriculture Films and Bags for many years.

These films are produced in various width and thickness using different polymeric compounds based on their application.

PlasticKar’ s agricultural films include:

Irrigation Roll
Greenhouse Film
Greenhouse Thermal Sheet
Low-Tunnel Film
Mulch Film
Soil Disinfection Film
Vineyard Cover
Banana Bunch Cove

By using a variety of additives, it possible to create specific features in agricultural films.

Some of these additives improve the product durability and life-time, while some others enhance the diffusion, thermal and mechanical properties.

Below are some of the additives and their effects:

Anti-Dust

Facilitate the removal of dust, soil and dirt stuck on the outer film surface with rain or a simple wash.
Preventing the reduction of light transmitted through the greenhouse cover.

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.

EVA Copolymer

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

UV-Stabilizer

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.

Disease Control Filter

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.
