The agricultural film industry market implies huge development potential

The rapid development of the agricultural film industry has made great contributions to improving land productivity, enhancing agricultural disaster resistance, achieving stable agricultural production and high yield, promoting the optimization of planting industry structure, enhancing the effective supply of agricultural products, and increasing farmers' income. Poor conditions have even more significance. In recent years, with the acceleration of new urbanization and agricultural modernization, there is more and more room for the development of agricultural film. and with“Ecological high-quality agriculture”(that is, the new goal of fully applying modern and future new energy, new materials, new equipment, new information, new biotechnology and other armed agricultural high-tech systems and production models), which also puts forward new and higher requirements for agricultural film , which is also a major development opportunity. Modern agriculture puts forward new requirements for agricultural film. At present, my country has a complete range of agricultural film products, and it is the country with the highest production level of thin agricultural film in the world. Various single-layer and multi-layer composite shed films with functions of longevity, dripping, heat preservation, anti-fog, antibacterial, light conversion, high light transmission, etc. Special agricultural films for solar greenhouses, vegetables, fruits, flowers, tobacco, cotton, silage, etc. have been widely used, among which there are many innovative products with Chinese characteristics, suitable for national conditions and international competitiveness. reach the international advanced level. The structure of agricultural film products has been optimized to a certain extent, and functional agricultural film products have accounted for about 50% of the total agricultural film. However, while seeing the achievements, advantages and bright prospects of the industry, we should also clearly recognize the problems and deficiencies existing in the industry. First, the overall technology and management level are still far from developed countries; second, the production concentration is low, overcapacity, and the proportion of mid-to-high-end and functional agricultural films is low, which leads to disorderly competition and market chaos; third, Variety, quality and function can not fully meet the requirements of modern agricultural cultivation technology and the country's high quality, high efficiency, environmental protection and resource conservation. Two problems should be paid attention to in the development of agricultural film. The plastic film should strive to realize the environmental protection and clean production of agriculture, and continue to increase the development of functional film and the development and application of new materials. On the one hand, develop and popularize functional mulch films such as longevity, drip weeding, warming, and insect control to ensure that spring mulch and autumn mulch can still be recycled. The recyclable mulch films produced by some enterprises in Gansu with a working time of up to 18 months, such as anti-aging, silver and black, are very popular. Association Outstanding Achievement Award. On the other hand, accelerate the development and application of new resins such as modified pet anti-aging mulch. In particular, it is necessary to speed up the progress of the farmland experiment of completely biodegradable plastic film. There must be new breakthroughs in technology In order to promote technological progress and technological innovation in the plastics processing industry, the China Plastics Association has clarified that the plastics processing industry“Functionalization, Lightweight, Micro-molding”Development trends and directions. At present, there are eight urgent problems to be solved in the development of the agricultural film industry, such as the modification of degradable plastic polylactic acid; the industrialization of high-transparency function and life-span synchronization films and high-performance water-saving equipment; the production of long-term photoecological and light-conversion agricultural films technology; key technologies for bio-based plastic processing and equipment; recycling and high-value utilization of waste plastic film; long-term dripping and fog elimination agricultural functional shed film and polymer-based nanocomposite coating; Application; agricultural film thinning coating coating device technology research, etc. It is an important task to solve the self-cleaning of the surface of agricultural film and keep it light transmittance for a long time. Especially after the successful development of the function and life-span synchronous film, due to the influence of the natural environment, this long-life functional film needs to solve the surface self-cleaning. Therefore, to speed up the research and development of new resins, nano-scale, thermal insulation agents, and antistatic agents, and to strengthen the self-cleaning treatment of the film surface, it is necessary to make a difficult choice between technical feasibility and low cost. It is necessary to speed up the development of light conversion agents with high spectral matching degree and synchronization of fluorescence attenuation and agricultural film life, for the production of special functional films such as light conversion greenhouse film, light conversion thermal insulation film, light conversion reflective film, etc. Provide a reliable guarantee, and at the same time, qualified scientific research units and enterprises should pay close attention to the research on the production characteristics of various special fruits and vegetables, analyze the different wavelength bands of light required by each, and gradually establish a database in this area to create conditions for the development of special films for special fruits and vegetables. . It is necessary to strengthen the research and development of high-end shed film, and increase the promotion and application of online coating of po film and multi-functional composite film. The high-end agricultural film market has broad prospects and is an important field of the high-end strategy of the agricultural film industry, and it is also an important development direction of the agricultural film in the future. It is necessary to strengthen the research and promotion of functional coating liquid, speed up the production of agricultural film ultra-thin coating coating equipment, speed up the localization of high-efficiency, energy-saving and intelligent multi-layer supply equipment, and provide equipment technical support for the agricultural film industry.
