1. Packaging materials must meet the requirements of relevant national standards and regulations, such as GB/T 19148-2011 "Specification for Plastic Bottles for Pesticide Packaging" and so on.

2. Packaging materials need to have good physical properties and chemical stability to ensure the quality and safety of pesticide packaging.

3 . Packaging materials need to have good permeability and barrier properties, which can effectively prevent the influence of light, oxygen, water and other external factors on pesticides.

4. Packaging materials need to have good sealing properties, which can effectively prevent the leakage and volatilization of pesticides in the packaging process.

On the basis of the above standards, according to the characteristics of different pesticides and the different use environments, different packaging materials and structural forms such as polyester bottles, polyethylene bottles, and high barrier bottles can be selected.
