            The main raw material of PP strapping is polypropylene drawing grade resin, which is colorless and transparent solid particles with a specific gravity of 0.93. Good plasticity, bending resistance, strong breaking tensile force, lighter material, bright color, easy to use. Used in packaging in multiple industries, when purchasing p, customers often ask how many meters are in a roll of packaging tape. So what factors affect the meters of PP strapping?

PP strapping

           1. Design factors of screw set parameters and screw configuration. The different screw settings can make the extrusion yield vary greatly. The high-shear total screw has high resistance due to its screw groove and its mixing elements, which reduces the conveying capacity of the material flow and therefore reduces the yield. When designing the nut, it is necessary to consider both the plasticizing effect and the problem. Yield issues.

           2. The unreasonable formula of PP strapping has a great influence on the yield. Good formula design can increase output by more than 10%. The scorching time of the plastic must meet the requirements of safe extrusion at the highest speed of the screw, which is essential to increase the extrusion output.

          3. The unreasonable selection of temperature distribution in the feeding section, plasticizing section, extrusion section, die head, and screw sections will also affect the extrusion yield of PP strapping. Due to unreasonable temperature selection, the yield can reach 20%. Or higher. It is especially worth noting that the temperature of the feeding section is the most sensitive to the effect of yield, and different temperatures should be selected according to different plastic properties.

          4. The unreasonable design of the flow channel structure of the machine head affects the extrusion yield of the packing belt. An unreasonable design of the flow path of the nose will increase the resistance of the flow path. Therefore, when designing the head runner, under the premise of satisfying the extrusion quality of the strapping, the resistance of the head runner should be reduced as much as possible, and the corresponding structure should be designed.

         These are all factors that affect the number of meters in pp strapping. Therefore, when we buy pp straps, we not only look at the number of meters of the straps, but also the quality of the straps.
