(Summary description) The virgin PP strap is made of polypropylene resin as raw material through high-temperature extrusion, stretching, embossing, cooling, shaping, winding and packaging. It has the characteristics of anti-corrosion and anti-fouling, safety and reliability, simple operation, clear pattern, uniform color and so on. After the environmental protection packing belt is used up, it can be used again.

Information

             The virgin PP strap is made of polypropylene resin as raw material through high-temperature extrusion, stretching, embossing, cooling, shaping, winding and packaging. It has the characteristics of anti-corrosion and anti-fouling, safety and reliability, simple operation, clear pattern, uniform color and so on. After the environmental protection packing belt is used up, it can be used again.

pp strapping

             The virgin PP strap produced by pure polypropylene is in a fully transparent state, the PP strap produced by polypropylene plus masterbatch is translucent, the PP strap produced by polypropylene plus recycled materials is basically opaque, and the polypropylene plus masterbatch and recycled materials are basically opaque. The straps produced are completely opaque. There is also a packing belt made of fully recycled materials and calcium carbonate powder sandwich materials. Only the surface of the belt is the raw material, and the rest are calcium carbonate powder. The packing belt made of completely recycled materials is relatively soft.

         Polypropylene is a recyclable material. Among the above strapping straps, only virgin PP strap made of pure PP materials can be fully recycled and reused, and only a small part of the recycled material straps can be reprocessed and reused. There are generally two ways to treat recycled waste PP, one is to use it directly, and the other is to use it after modification.

            Direct use means that there is no need to carry out various kinds of modification to process waste PP through certain classification, cleaning, crushing, plasticization, directly processing and forming or processing into shaped products after granulation. The advantages of this method are simple process and low cost of recycled products. Waste PP can be regenerated into pellets, flocculent materials, etc., and then mixed with the original resin to manufacture products with the same purpose as the original resin or melt and solidify them, and directly form into various products. In addition, melting and recycling waste PP plastics, that is, heating and melting waste plastics and re-plasticizing them, is also a method of direct use.

         Modification treatment is to modify the waste PP through physical or chemical methods to gradually restore the original mechanical properties to meet the requirements of reuse. The modified recycled PP has improved or enhanced mechanical properties and can be used to make higher-grade plastic products.

         The above is the relevant introduction about the secondary utilization of virgin PP strap. If you want to know more related information, please pay attention to our website. If you have a demand for virgin PP straps or other packaging products, please contact us or leave a message online.
