What is the reuse technology of agricultural plastics?
Agricultural film, also called plastic film, is mainly composed of polyethylene, which is used to cover farmland to raise ground temperature, ensure soil moisture, and promote seed germination and rapid seedling growth. It can also inhibit the growth of weeds. See if the product meets the national mandatory standards. The national mandatory standard thickness of agricultural film is 0.008 mm, but many agricultural films sold in the market are 0.004 mm, which does not meet the standard. After using the unqualified agricultural film, it can not only keep warm and moisturize, but also easily cause "white pollution" of farmland. Some dealers fry 0.008 mm agricultural film into "environmental protection agricultural film" to confuse farmers. In fact, 0.008 mm plastic agricultural film is easier to recycle than 0.004 mm plastic agricultural film. The real environmental protection agricultural film refers to biodegradable biological agricultural film. This kind of agricultural film has not been popularized at present because of its high production cost. Buy agricultural film according to the purpose. If you blindly choose to use it as an ordinary agricultural film or not use it according to the manufacturer's requirements, it will waste its functionality, so you should choose it purposefully and carefully check the actual performance of its functional characteristics.

The raw material market fluctuates greatly. Affected by many factors, such as the release of new ethylene production capacity at home and abroad, the recent drop in international oil prices and weak global demand, the price of polyethylene has been slowly declining recently. Among them, the market price of LLDPE, as the main raw material of plastic film, is only about 1. 1 10,000 yuan/ton, down by 10% year-on-year, with no obvious signs of rebound, which has hit the confidence of dealers in the future of plastic film and shaken the confidence of plastic film manufacturers. The price of grain and cotton fell, which dampened the enthusiasm of farmers to use agricultural film. Since 20 12, the price of cotton has been hovering at a low level, the spot price of corn has fallen steadily after the Spring Festival, and the futures price has fallen sharply recently, which has seriously dampened farmers' enthusiasm for planting corn and cotton, reduced the demand for plastic film, and caused the agricultural film market to shrink. Overcapacity is very serious. At present, the effective production capacity of agricultural film in China exceeds 4.5 million tons, the total demand is only 2.2 million tons/year, and the overcapacity exceeds 1 times. In this case, when the market is good, enterprises will invariably increase the operating rate of devices, increase market supply, and suppress the downward price; When the demand shrinks, enterprises have to passively reduce the operating rate and minimize losses. This is also the fundamental reason why agricultural film enterprises have made meager profits in good times and increased losses in bad times over the years. That is, the ground cover film, usually transparent or black PE film, but also green and silver film, is used for ground cover to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from harming crops and diseases caused by some microorganisms, and promote plant growth.
