China is currently the second largest country in the world in the production of pesticides. It can produce more than 200 varieties of raw drugs, with an annual production capacity of over 750,000 tons and a production of nearly 400,000 tons, of which two-thirds are liquid formulations.
At present, only 10% of plastic bottles are packaged in pesticides. For a long time liquid pesticides have been packaged in glass bottles. Their main disadvantages are:
The first is high breakage rate. According to statistics, glass bottle packaging liquid pesticides used from the factory to farmers, the breakage rate is generally 10-20%, not only increase costs, but also pollute the environment.
The second problem is that the closure of the glass bottle is not strict and the leakage remains high.
Third, the measurement is inconvenient, the scale on the bottle is not very accurate, and it is easy to cause excessive use or insufficient dosage when used, which leads to the acceleration of the resistance of pests and pathogens.
In addition, the bottle is difficult to recycle, while the glass bottle is heavier, increasing the transportation costs. The quality of pesticide packaging is directly related to the safety and interests of hundreds of millions of farmers. In order to change the problems existing in the packaging of liquid formulation pesticides, the former Ministry of Chemical Industry proposed the development strategy of plastic substitute glass in 1992.
For several years, the plastics industry has actively cooperated with chemical pesticides departments to promote the use of plastic bottle packaging. Now more than 100 million are used each year to promote the improvement of pesticide packaging. Practice has proven that plastic bottle packaging pesticides will have a good development prospect.
