  In the production process of PP packaging slot, due to improper formulation, or the plastic processing process is unreasonable, resulting in PP packaging slot brittle, the main characteristics are: dismounting, cold burst fracture. The following baoding donghe plastics industry for everyone to provide PP packaging products, poor physical and mechanical properties.
  1. Too much packing
  Because the price of PP slot is lower and the price of raw materials is higher, many manufacturers reduce the quality of PP slot as well as the cost. Because of the formula composition, the most direct and effective way is to increase the filling. With the development of technology, superfine light activated calcium carbonate, even nanometer calcium carbonate, which not only plays a role of increasing rigidity and filling, but also has the function of modification. Some manufacturers now add calcium carbonate to 20-50 quality to reduce costs, which greatly reduces the size
