Manufacturing and processing methods for plastic bottle materials
Plastic bottles are polyester, polyethylene, polypropylene as raw materials, added the corresponding organic solvent, after high temperature heating, through the plastic mold through blow molding, squeeze, or injection molding plastic containers. Liquid or solid disposable plastic packaging containers such as agricultural and veterinary drugs. Plastic bottles are not easy to break, low cost, high transparency, food grade raw materials and so on.
There are many ways to manufacture polyethylene, one of the most common, is at 200 to 300 degrees C high temperature and 1000 to 2000 atmosphere pressure, the ethylene polymerization into. In polyethylene, do not doped with other substances. Both have high stability, so there is no need for an admixtures, plasticizers, and stabilizers and plasticizers are mostly toxic or highly toxic.
Plastic bottles are filled by the gun mold after a certain temperature pressure blow molding, can be processed by the billet, can also be directly by injection molding blow molding a machine processing form
