What are the raw materials for making plastic steel straps?

PET packing strap  is a kind of polyester strapping formed by extruding PET as raw material and unidirectionally stretched. It is a perfect strapping instead of steel strap. It has been widely used in brick kilns, steel, aluminum ingots and textiles. , Wood industry and other industries.

In the early stage of the development of the industry, around 2002, due to the immature production technology, polyester chips were basically used to produce plastic steel belts. Polyester chips usually mean that the polyester raw materials obtained by polymerization are generally processed into flake particles of about 4*5*2 mm.， usually for Automatic strapping machine use .

Although the quality o is good, its cost is relatively high. With the development of plastic strap production technology, automatic temperature control and other technologies, the industry can gradually use recycled carbonated beverage bottle flakes for production, as shown in the following figure. Furthermore, this approach follows the strategy of sustainable development and adheres to the development concept of “green water and green mountains are golden mountains and silver mountains”.

Since 2002, the amount of plastic-steel strapping has increased at an annual growth rate of 500%, resulting in a large number of used plastic-steel straps, which has given rise to the demand for collecting and crushing straps. The plastic steel belt manufacturers with better technology have already used crushed packing belts as raw materials to produce plastic steel belts. Since the interaction force between plastic molecules is damaged and reorganized many times, there is a problem of low viscosity, so some tackifiers are used to increase the viscosity.
