The development of pesticide packaging change

Our country is a traditional agricultural country, as the name implies, pesticide is, as an essential part of modern agricultural production in addition to the pest confirmed harvest important tool. According to the relevant departments to statistics, our country has more than 6000 kinds of modern pesticide formulations, including liquid formulations of pesticide packaging bags for more than half. With the unceasing change of pest form, also led to the upgrading of pesticides. With the improving of the packaging technology, pesticide packaging materials and form also changes have occurred many times: in the past, the glass bottle is the main form of pesticide packaging, with its mature technology, low cost, high chemical stability, good barrier property, and not easy to leakage and dominant for a long time. But the glass used in pesticide production, transportation, pesticide packaging process is easy to broken, this will not only cause economic losses, and may lead to poisoning. In addition, the weight of glass packaging pesticides is bigger, transportation will inevitably increase the cost of transportation. In the 1990 s, under the call of the original chemical with plastic instead of glass, plastic container gradually entered the field of pesticide, from single to plural, from oneness to high barrier property development path. At present, used in liquid packaging pesticides are mainly the single plastic PE bottles, PET bottles and HDPE bottles and so on, but because of its material single, cut off the volatile of the role of oxygen, water vapor permeability and pesticide, it is difficult to accomplish the storage of pesticides for a long time. With the enhancing packaging requirements, high barrier property of pesticides plastic packaging containers on the stage of history. So-called barrier property of plastic bottles is with coating, composite, blending, such as a special process, to make plastic bottles have excellent cut off oxygen, water vapor and the role of organic gases, qualitative light, changeable concurrently at the same time, strong and other excellent properties.
