Packing tape is a widely used consumable packaging material. There are two types of PP packaging tapes that we commonly use: cored tapes and solid tapes. From the quality of products, there are transparent A grade, transparent B grade, A grade, AB grade, B grade, BC grade and C grade. From the point of use and its types, it can be divided into hand playing belts and machine playing belts, and the machine playing belts are divided into fully automatic machine belts and semi-automatic machine belts. From the scope of use can be divided into packing tapes and handicrafts with packaging, as well as printed ribbons and non-printed ribbons and so on.
The pp strap is mainly made of PP material, which is mainly due to the chemical and physical properties of PP polypropylene. PP is a semi-crystalline material that is harder and has a higher melting point than PE. Due to the high degree of crystallinity, this material has very good surface stiffness and scratch resistance. At the same time PP has excellent formability and mechanical strength higher than PE. Polypropylene PP has good water resistance, chemical resistance and electrical insulation.
Since PP material is an accessory product of petroleum, the price will be largely influenced by the price of oil. From an environmental point of view, resources are limited, which requires that all manufacturers need to be able to recycle to save resources. The environment-friendly packing belt is not filled with any filling and impurities. After use, it can also be used for crushing and pumping. Generally, many of our common inexpensive packaging belts contain dozens of fillers. This strap only has a thin layer of PP material that is better. However, this type of packing can not be recycled after use. Therefore, from the perspective of long-term and environmental protection, the production and extensive use of eco-friendly premium PP strapping will replace the core tape step by step, and this will also be an inevitable trend.
