Xiong Yu Xin plastic packaging plant Biansi process include: raw materials modification, blend, colored plastic bags, plastic bags filled Dalian factory, preparation, anti-aging, anti-degradation problem, the process of extrusion temperature, pressure, flow regulation Traction control and rheological behavior than the extrusion process, the power consumption, yield problems, drawing process, blow-up ratio, draw ratio, cooling crystallization, orientation, heat stereotypes custom colored plastic bags, during winding . The molding and spindles of 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, has excellent low temperature properties, good chemical stability, resistance to most acid-base erosion , room temperature, soluble in common solvents, water absorption of small plastic bags Tianjin price, excellent electrical insulation properties; but Polyethylene is very sensitive to environmental stress, heat aging properties of polyethylene poor because of different varieties, depending on the standardization of molecular structure and density of the domestic packaging industry behind the development of the packaging industry. Some standards inconsistent with the actual product, the content is still stuck at the level of a decade ago. For example, the "Container" standard was developed by the transport sector, "cement bags" standard building materials sector to develop, "geotextile" standard was developed by the textile sector, "woven" standard department of plastic and so on. Due to a lack of interest among woven products targeted for use with industry, also known as snakeskin. Is a plastic, packaging, the raw material generally polyethylene, polypropylene and other plastic materials chemistry. The main terms of bags: Plastic bags are polypropylene, polyethylene resin as the main raw material, extrusion, stretching into the flat, and then by weaving, the preparation, the bag is made. Foreign production mainly of polyethylene (PE), polyethylene (PE), ethylene is polymerized a thermoplastic resin obtained. Full consideration, there is not a unified, effective, taking into account the interests of standards.
