EC pesticides because of its solvent containing more aggressive, so the latest in China and has been promulgated in March 1, 2001 from the implementation of the "pesticide EC package" in particular should be clearly used glass bottles, high-density polyethylene bottles and fluoride Equivalent to other material bottles (bags), etc. to packaging.

It should be said, PET bottles (PET) for some of the solvents used in EC pesticides have a good barrier effect, but PET because of its easy to absorb moisture in the environment, leading to excessive pesticide water, decomposition or failure of this congenital deficiency in the international Is restricted to use. In terms of barrier effectiveness, glass bottles, aluminum bottles, multi-layer co-extruded bottles (the inner layer of nylon or polyvinyl alcohol) and fluoride bottles have good performance. But relatively speaking, the glass bottle because of its vulnerability to damage caused by Achilles heel and the application of declining. Aluminum bottles are more costly. On the cost, the multi-layer bottle is less than fluorinated bottles; the effect, 100 ml and below the multi-layer bottle is better than fluorinated bottles, but the greater the size, the stronger the competitiveness of fluorinated bottles. In this case,
As the inner layer of multi-layer bottles of nylon or polyvinyl alcohol depends on the type of solvent in the pesticide, fluoride bottle wall polytetraethylene (plastic Wang) and other fluorine plastic layer, the composition is very complex, so the choice of these two barrier bottles , The product compatibility test must be carried out to confirm the blocking effect. Third, the negative pressure due to oxidation caused deformation of the solution.

For pesticide manufacturers, consider the replacement of solvents or emulsifiers, control the impurity content of raw materials in order to improve the purity and reduce the possibility of oxidation. At the same time, you can follow the example of international companies, nitrogen filling in the pesticide, in order to reduce the oxygen content of air retention to stabilize the composition of pesticides and avoid oxidation of the dual purpose.
