what raw materials are used to make plastic?

Because of the particularity of the selected production materials, the plastic turnover box has a great impact on the hardness and softness of its texture. Many customers in the purchase of plastic turnover box, after a period of use, have a certain understanding of the turnover box, some will think that the turnover box hard some good, and some think that the turnover box soft some good. These two points of view are right, and wrong, from the point of view of the manufacturer, the turnover box is hard or soft, according to the use of customers.
The main raw materials for the production of plastic turnover boxes are polypropylene (PP) and polyethylene (HDPE), which have very different characteristics.
HDPE material is characterized by good flexibility, the use of HDPE material production turnover box is usually relatively soft hardness, and has a certain flexibility, good quality. If the hardness of the turnover box produced by HDPE material is hard, it indicates that the turnover box has been used or stored for a long time, begins to age and is easy to damage.
PP material is characterized by good hardness and high temperature resistance. Therefore, the hardness of the turnover box using PP material is relatively hard, and it has good adaptability to the high temperature environment and good quality. If the hardness of the turnover box produced by PP material is soft, it means that the manufacturer may add other materials during production, and not completely use PP materials.
