The quality of the packing belt is good or bad. It depends on the high purity of the polypropylene in the packing belt. There are many kinds of packing belts on the market: pure polypropylene, polypropylene plus masterbatch, polypropylene plus recycled material, polypropylene plus recycled material. And masterbatch. The packing belt produced by pure polypropylene is fully transparent, the packaging of polypropylene and masterbatch is translucent, the packing belt produced by polypropylene plus recycled material is basically opaque, and the packing belt of polypropylene plus masterbatch and recycled material is produced. Completely opaque. There is also a packing belt produced by the whole recycled material and the calcium carbonate powder sandwich material. The packing belt produced by the completely recycled material is relatively soft, and the belt of the sandwich material only has the surface as the raw material, and the rest are the calcium carbonate powder (lime powder). The quality of the strap is completely dependent on the purity of the polypropylene. The higher the purity of the polypropylene, the better the tension of the strap.
