Polypropylene (PP) prepared by the polymerization of propylene and a thermoplastic resin is obtained. There was an isotactic, syndiotactic and atactic material was three configurations, isotactic industrial products as a main component thereof. Polypropylene also includes a small amount of propylene and copolymers, including ethylene. Usually translucent colorless solid, odorless, non-toxic. Because of the structure of regular and highly crystallized, so the melting point of up to 167 ℃, heat, steam sterilization products available is its outstanding advantages. Density of 0.90g / cm3, is the lightest common plastic. Corrosion resistance, tensile strength of 30MPa, strength, rigidity and transparency better than polyethylene. The disadvantage is the low temperature impact resistance, easier to aging, but can be modified and the addition of antioxidants to be overcome. Bags color is generally white or gray Used tons of bags for sale, non-toxic and tasteless, bodily injury is generally small, although it is manufactured by a variety of chemical plastics, but its strong environmental protection, and recovery of larger efforts;. Woven main raw Publisher: Published: 2014-09-23 Read: 5 times woven bags mainly in terms of the main raw materials: plastic bags are polypropylene resin as the main raw material, extrusion, stretching into Biansi , then by weaving preparation, bag together. The main types of foreign production of polyethylene (PE), mainly for the domestic production of polypropylene (PP), is prepared by polymerization of ethylene a ... ...... woven mainly in terms of: Plastic bags are polypropylene resin the price of the main raw material used tons of bags, by extrusion, stretching into the flat, and then by weaving preparation, very versatile bag made of woven bags used tons, mainly for various items to be mounted and used tons of packaging Which bag is widely use in industry; plastic bags are polypropylene resin as the main raw material, extrusion, stretching into the flat, and then by weaving, bag together.
