The lunch box machine is currently the most used machine in the fast food industry, and the fast food box produced by it has the characteristics of heat resistance, softness and corrosion resistance. It is also a plastic molding machine, like the cup making machine, which is a device for producing plastic products.
        Whether it is a lunch box machine, a cupping machine or a cup making machine, it is a kind of plastic molding machine. The materials needed for their production are plastic or polymer, and plastic is a plasticity and super strong material. Therefore, the plastic machinery is also a rapid development, here to introduce the changing characteristics and advantages of plastics.

         Since the plastic is in a glassy state at normal temperature, if heated, it becomes a highly elastic state, and then becomes a viscous flow state, thereby having an excellent plasticity material, and the product can be manufactured by many high-productivity molding methods, thereby saving raw materials. : It saves man-hours, simplifies the process, and has low technical requirements for workers, and is easy to organize mass production. Therefore, the use of plastic machinery will become more and more, and it has become one of the most used machines in the world.
