Plastic bags production methods plastic flat, woven industry referred to as: flat, also known as cut fiber, which is the production of plastic woven basic material, flat from specific varieties of polypropylene, polyethylene resin by melt extrusion film, and then cut into strips lengthwise, after all bars while heating drawing orientation stereotypes mortar bags, eventually wound into flat yarn spindles, for woven braid. Xiong Yu Xin plastic packaging plant, plastic conductive particles and its preparation method 40, using materials and methods for filling plastic granules emptied 41 shipping containers, plastic particles tend to have adhesions, especially crystallization method and apparatus for 42 PET and PU particles a long-fiber-reinforced plastic particles rolling production device 43, waste plastic recycling granulator plastic packaging plant Yu Xin Xiong Biansi process include: raw materials modification, blending, shading, custom bags filled with fruit, preparation, aging, Anti-degradation problems, the process of extrusion temperature, pressure, flow regulating the rheological behavior of the control and traction than the extrusion process, the power consumption, yield problems, drawing process, blow-up ratio, draw ratio, cooling crystallization, orientation ., heat styling issues in the process of forming and winding spindles quality testing and other technical problems are mainly used for packaging textiles, knitting cotton goods, clothing, shirts, etc. (4) PVC plastic bag use:. A gift bag. ; B. luggage bags, knitting cotton goods bags, cosmetic bags; C. (zipper) paper bags, polyethylene bags, odorless, non-toxic, feel like wax bags, has excellent low temperature properties, chemical. good stability, resistance to most acid-base erosion, room temperature, soluble in common solvents, water absorption fine print bags, electrical insulation properties; but Polyethylene is very sensitive to environmental stress, heat aging poor polyethylene. nature because of different varieties, depending on the molecular structure and density mortar packing bags _ Xin Yu (certified) _ Zhangjiakou bags provided by Xiong Yu Xin plastic packaging plant. Xiong Yu Xin plastic packaging plant (www.xinyusl.com) Hebei Baoding, a leader in composite packaging products, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Yu Xin leader in packaging with the staff warmly welcome all inquiries negotiations to create Xin Yu packing a better future.
