Three kinds of multi-functional high-tech agricultural special agricultural films are introduced.

1. Biological control film - TUV3798AF. The invention and application of the greenhouse has revolutionized agricultural production technology and provided an all-weather production environment, but its enclosed space has also become a breeding ground for pests and diseases. The biological control film is used to block the entry of ultraviolet rays with a wavelength below 375nm, which can make ordinary insects and butterflies lose their activity and fecundity, thus reducing the pathogens that are carried and transmitted by them.

2. Thermal insulation and cooling film - TUV3758AF. All greenhouses face a common problem, that is, high temperature in summer, which leads to the heat accumulation effect in the greenhouse. Therefore, the phenomenon of high temperature not only causes an unsuitable working environment, but also hinders the growth of crops and increases the frequency of pests and diseases. The agricultural film uses the principle of reflecting a large number of near-infrared rays (wavelength 700-1600nm) to achieve the purpose of cooling, and the highest temperature can be lowered by 5°C-8°C. The best PAR (400-700nm) transmittance of 91%, 72% of scattered light, creating a shade-free greenhouse is conducive to crop growth. It can still achieve good thermal insulation effect in winter.

3. Multifunctional special film TUV3950AF. The agricultural film is suitable for temperate, frigid and other regions with short sunshine, low temperature and cold winter. This variety has the following seven characteristics: (1) High thermal insulation effect; (2) High light transmittance, which increases the light in the greenhouse, enhances the photosynthesis efficiency, can improve the planting density and increase the yield, and the total light transmittance can reach 90%. %; (3) Longevity; (4) Dust-proof treatment on the surface; (5) Anti-drip treatment on the inner layer, high content of UA stabilizer, can make the service life more than 5 years; (6) Large size, the widest Up to 16M and length up to 1000M, therefore, any size does not have to be spliced.

The multi-functional three-layer co-extruded high-tech agricultural film is not only to provide a place for crops to shelter from wind, rain and heat preservation, but its main function is to block the ultraviolet rays that hinder the growth of crops, and let the crops that are conducive to the growth of crops be blocked. Light (i.e. PAR) enters. That is to say, through this function, the crops can be harvested earlier, the quality can be improved, and the output can be increased, thereby increasing the production efficiency of farmers.

Main features of longevity drip-free greenhouse film 1
The functions of longevity drip-free greenhouse film are as follows: thermal insulation effect, dripping effect, dustproof effect or other functions, which can make the film play a positive role to protect and help the growth of crops.
Main features:
1. Proper selection of materials, processing and quality control for strength and toughness can ensure that the film has good tensile strength and toughness. The use of the new generation of raw materials can make the film have super strength and toughness, and thus can reduce the thickness of the film (the use of raw materials) to achieve the same strength, so as to save farmers' use costs.
2. The longevity non-drip greenhouse film contains special and effective UV stabilizers, which can protect the film from damage due to ultraviolet radiation, so as to achieve the purpose of long-term use.
All recipes come from European technology.
The content of UV stabilizer in PEP film is generally 15~30% more than others, so when it is actually used, its life is always longer than what we promise.
3. Thermal insulation effect The three-layer thermal insulation film contains EVA and infrared absorbers, which can effectively absorb infrared rays and reduce the rapid disappearance of heat energy at night, so as to achieve the effect of thermal insulation. Its benefits:
a. Protect crops from being damaged by frost and low temperature.
b. It can avoid the sudden drop in temperature at night and increase the temperature in the greenhouse.
c. Reduce the use of energy.
d. The yield of crops can be greatly improved.
e, can be harvested early.
f. It can improve the quality of crops.
4. Good light transmittance is very important to the growth of crops. PEP film has rich production experience, good equipment and proper selection of materials to ensure the best light transmittance of the film.
5. There are many practical cases of scattered light that prove that scattered light has a good positive effect on the growth of plants, especially in areas with strong sunlight and sufficient sunlight, because scattered light can make the light irradiation more uniform, even in leaves (crops). ) overlapping parts can also absorb enough light. And because the diffusing film can reflect a part of the infrared rays, it has the effect of cooling and can prevent the plants from being burned by the sun. The high and low scattering rate can be adjusted according to the needs of customers and crops.
6. Droplet effect Due to the effect of temperature difference and water evaporation, water droplets are easily formed on the surface of the longevity drip-free greenhouse film. The condensation of water droplets on the film has a negative effect on the growth of crops, because water droplets will reduce the light transmittance of the film. and easily lead to the formation of pests and diseases
