Food processing, packaging equipment running at a faster rate, improve reliability, and because of food processing and packaging process of cleaning, milling, sterilization, oil-free, aseptic packaging process complexity, so the packaging equipment reliability and life of critical components proposed new stringent requirements previously used traditional materials such as: Nylon, ultra-high molecular weight polyethylene, Teflon, graphite and other materials have been unable to meet the increasingly high-speed packaging equipment, wear, corrosion-resistant, non-toxic requests. And because a plastic PEEK most excellent high temperature, wear resistance, corrosion resistance, overall performance, high strength and the most successful application to solve the food processing and packaging machinery and equipment, key parts of the design, manufacture and use of technical problems.
