      Plastic packaging bags (plastic vest bag) in study of biodeg

      The 08 years since the introduction of a "restrictions on the production, sale, use of plastic packaging bags of notification" plastic limit order. Notification specified, since June 1, 2008, prohibit the production, sales, the use of plastic bags less than 0.025 mm in thickness across the country. At the same time the ultra-thin plastic packing bag production of this specification into the eliminated category. Faced with this situation, the company must adjust product structure, according to the national industrial policy, the introduction of "biological degradation technology", the development and production of various plastics pollution can be reduced to zero plastic packaging products, supply market, has become a major technological innovation work I enterprise imminent, directly related to the survival with the development of enterprises. According to the current domestic research about biodegradable plastic raw material "PBS, PVS, PSM".
      Through the research, screening, we have chosen to Wuhan Huali environmental technology limited production of PSM products as raw materials. Through the research, screening, we have chosen to Wuhan Huali environmental technology limited production of PSM products as raw materials. Degradable plastics technology for the production of plastic packaging bags (vest bag, plastic bag) research and production application, bag. And has completed a series of experiment.
      At present we have basically mastered the processing temperature, now we mainly studies the PSM in our existing equipment on the precise temperature, one two three temperature zone, three pass temperature, film head temperature, temperature theory, three, temperature one two three District first membrane were: 160 ℃, 170 ℃, 180 ℃, 160 ℃ --180 ℃, in practice, because the material extrusion in the screw forward friction and shear heat is large, the material especially in area two or three, temperature is particularly difficult to control, will appear the phenomenon of high temperature, easy to form PSM burning coke materials, package materials will be in the film difficult, affecting the quality of products, our test is to identify, find a good temperature control screw suitable speed.
      The film needs to emit heat in the process of extrusion blow molding film, processing temperature of PSM and ethylene blend decreased, film cooling speed, there is no Lasheng, had been finalized, work out product without tension, we must study and solve the wind ring opening and a wind speed and traction speed matching with them the problem.
      After repeated testing, according to the relevant national standards, and explore suitable for Baoding climate characteristics, the best formula with our independent intellectual property rights in line with national standards, industrial technology innovation which is the project.
      In recent years, our country every year, the use of plastic has more than 5000000 tons, of which 30% of disposable plastic packaging materials and products difficult to recover.
      We introduce the Wuhan Huali environmental technology company "starch light degradation plastic bag" technology, has been in the second half of 2009 put into trial production of a number of "starch based degradable bags". From the national present the formulation of industrial policy, economic development and environmental protection requirements in terms of guiding ideology, the introduction of the "biological degradation technology" production "fully biodegradable plastic packaging bag (vest bag, plastic bag)" the economic, social, environmental benefits and prospects are Speechless can be said, this is an environmental engineering, the people's livelihood projects. Because the starch used as raw material cost is relatively high, although in line with national requirements for environmental protection, but because of the high price and sales volume is very small.
