Polypropylene straps include machine bag straps and hand bag straps, all of which can add a relatively large amount of calcium carbonate, but due to the certain rigidity of the bag with the bag, adding too much calcium carbonate will make the straps softer and affect the use on the baler.
The use of 400-grit heavy calcium carbonate in the packing belts is inexpensive and the processing fluidity is good enough to meet the requirements. In order to make the heavy calcium carbonate evacuated and symmetry in the plastic guess, the heavy calcium carbonate is first processed into a supplementary masterbatch. In recent years, the production skills of the supplemented master batches have undergone major changes, with fewer and fewer carrier resin factors, and the heavy calcium carbonate has been up to more than 85%. The processing machine configuration also accepts co-rotating twin-screw extruders. The products of different grades The costs are very different and can meet the needs of different users.
