Packing tape is a widely used consumable packaging material. The PP material produced can be divided into core-spun tape and solid-core tape; from the quality of the product, it can be divided into transparent A grade, transparent B grade, and A grade. , Class AB, Class B, Class BC and Class C, etc.; from the machine used can be divided into hand tapping, machine tapping (also divided into automatic machine taping and semi-automatic machine taping); from the scope of use can be Divided into packing tape and crafts tape for packaging; there are also sub-printed tape and non-printed tape, etc.
The packing belt is made of PP, mainly because of the chemical and physical properties of PP. The Chinese name of PP is polypropylene or propylene resin, and the English name is PolypropyleneResin. PP is a semi-crystalline material. It is harder than PE and has a higher melting point. The Vicat softening temperature of PP is 150C. Due to the high crystallinity, the surface rigidity and scratch resistance of this material are very good. At the same time, PP has excellent moldability and higher mechanical strength than PE. Polypropylene PP has good water resistance, chemical resistance and electrical insulation.
Since PP is a by-product of petroleum, the price will be largely 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. The environmentally friendly packing belt does not add any filling and impurities, and can be crushed and used after use; and in general, many of our common low-cost packing belts contain tens of percent of the filler. To put it bluntly, the inside is full of garbage. This kind of packing belt has only a thin layer of better PP material on the outside, but whether it can be recycled after use, the effect of recycling can be imagined. Therefore, from a long-term and environmentally friendly point of view, it is inevitable to produce and widely use environmentally-friendly advanced strapping belts and replace core-spun belts (recycled belts) step by step.
