PP packing belts PP packing belts are used for carton packing and are used with active balers.
The first of the PP strapping belts is that the temperature control of the extruder is usually in the range of 250°C to 280°C. The next step is cooling, after the material is brought out of the head, the temperature is very high, and it should be immediately cooled in water. Since the isotactic polypropylene simply generates a twin structure in the case of quenching, the twin crystal structure is loose. Simply stretch the orientation to obtain high quality products. This is followed by stretching. The intention of the stretching is to increase the longitudinal strength of the strap and reduce the elongation.
Stretching of PP strapping must be done in boiling water, usually using one stretch. The final result is embossing. After the stretched strap is passed through two striped rollers, it is pressed with a stripe. Its function is to add conflicts in the use, not to slip, and to look beautiful from the outside.
