High environmental protection PP packing belt is the necessity of market developmentPackaging belt is a widely used consumable packaging material. From the quality of PP material, it can be divided into core belt and solid core belt; from the quality of products, it can be divided into transparent a, transparent B, a, AB, B, Class BC and class C; from the machine used, it can be divided into hand belt, machine belt (also divided into full automatic belt and semi-automatic belt); from the scope of use, it can be divided into packaging belt and handicraft belt; and it can also be divided into printing belt and non printing belt, etc.
The packing belt is made of PP, mainly because of the chemical and physical properties of PP. the Chinese name of PP is PP or propylene resin, and the English name is polypropylene resin. PP is a semi crystalline material. It is harder than PE and has a higher melting point. Vicat softening temperature of PP is 150C. Due to its high crystallinity, the material has good surface rigidity and scratch resistance. Meanwhile, PP has excellent formability and higher mechanical strength than PE. Polypropylene PP has good water resistance, drug resistance and electrical insulation.
As PP is an accessory product of petroleum, the price will be greatly affected by the price of petroleum. From the perspective of environmental protection, resources are limited, which requires all manufacturers to be able to recycle to save resources. However, the environmental protection packing belt does not add any filling and impurities, and can be crushed and used after use. Generally, we are very Many common low-cost packing belts contain dozens of percent of fillers. To put it bluntly, the inside is full of garbage. This kind of packing belt only has a thin layer of better PP material on the outside, but can it be recycled after use? How can the recycling effect be imagined? Therefore, from the perspective of long-term and environmental protection, the production and wide use of environmental protection advanced packing belt are one step at a time It is necessary to replace the core band in one step.
