Production methods of plastic bags plastic flat color woven fertilizer bags, woven industry abbreviation: Biansi color bags, also known as cut fiber, which is the production of plastic woven basic material, flat polypropylene by a particular species , polyethylene resin film by melt extrusion, and then cut into strips lengthwise, various bars while heating drawing orientation stereotypes, 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 woven inner bag (3) and other regulatory matter, random objects and object syndiotactic three configurations, industrial products and other regulated material as the main ingredients. polypropylene also includes a small amount of propylene and ethylene copolymers, including usually translucent colorless solid, odorless, non-toxic, is the lightest of the common plastic. corrosion resistance, tensile strength of 30MPa pearl color film bags, strength rigidity and transparency better than polyethylene. The disadvantage is poor low temperature impact resistance, easier to aging of PVC film stretched over the findings of new technology to produce cutting filament and split fibers. 1950s, O · B · Rasmussen, through research, the use of stretch film extrusion methods and equipment, began producing woven fibers. By 1965, Europe began the industrial production of the one-way stretch woven flat yarn color film for the production of industrial packaging bags.
