plastic material is really make people love and hate, we love it because of its big function. In the current market, most of the container and pakaging products are made by plastic materials.Like most of cleaning container,plastic cups,plastic envelope,plastic packaging bag.etc are typical in plastic products. We can say most of the plastic products are produced and processed by sheet machine, so the value of this machine is obvious.On the other hand, we hate it because it caused a lot of pollution, the point is not in plastic material itself but in people how to use it. Now, more and more plastic packaging products applied to food industry which provides many convenience for people's life.However, a lot of plastic film and plastic packing bag waste everyday has become a great public hazard in city."White pollution" damaged natural environment and human health seriously. 
 At present, we have produced resin production in more environmental protection way for sheet extruder machine.It has eased the harm made by plastic foam. For environmental protection, cup making machine is just use this way to produce plastic products.Another fast food box making machine use large degradability material to produce plastic products instead of foaming way.
