There exist high toxic and strong corrosive organic solvents such as methylbenzene and dimethylbenzene in liquid pesticide, therefore materials used in packaging pesticide should have strong anti-corrosive and high barrier property. At present, common flexible materials in domestic market mainly include PET/Al/CPP（or PE）, PET/VMPET/CPP（or PE） dry laminated films, PP or PE coextrusion film including PA or EVOH and PET/PVDC （or EVOH） /CPP （or PE） transparent film. Meanwhile polyurethane adhesive is often used. Discarding and dumping in landfills and burning are two main ways for waste disposal, which are detrimental to environment and physical health and some appropriate measures should be taken. In future, researching and developing degradable materials and water soluble film is a green and environmental-friendly way to liquid pesticide packaging.
