PP means polypropylene. PP strapping is one of the lighter common plastic packing belts. It has good plasticity, strong breaking force, bending resistance, light specific gravity and easy to use. It is processed into strapping belt and is favored by various industries. So in use, how to identify PP strapping? PP strapping manufacturers teach you!

pp strapping

First of all, through the appearance observation, the appearance of PP strapping is translucent to opaque, and the texture is transparent film. Second, it can be identified by combustion. PP strapping is combustible in the flame. When burning, the upper end of the flame is yellow and the lower end is blue. After leaving the flame, it slowly goes out or continues to burn, with melting and dripping phenomenon, and the smell of paraffin can be smelled. Through the above two steps, PP strapping can be identified.

How can we identify the quality of PP strapping? The quality of strapping depends on the purity of polypropylene. At present, there are many kinds of packing belts in the market: pure polypropylene, polypropylene plus masterbatch, polypropylene plus recycled material, polypropylene plus recycled material and masterbatch. The strapping produced by pure polypropylene is completely transparent, the strapping produced by polypropylene plus masterbatch is translucent, the strapping produced by polypropylene plus recycled material is basically opaque, and the strapping produced by polypropylene plus masterbatch and recycled material is completely opaque. Therefore, we can see the purity and quality of polypropylene by observing the transparency of the packing belt.

In addition to the above, there is also a kind of fully recycled material and calcium carbonate powder sandwich material, which is completely recycled material. The packing belt produced by the fully recycled material will be relatively soft. Only the surface of the belt of the sandwich material is the raw material, and the rest are calcium carbonate powder. In the final analysis, the quality of the packing belt completely depends on the purity of polypropylene. The better the quality, the better the tension of the packing belt.

The above is about the identification and quality analysis of PP strapping. If you want to know more about the knowledge and information of packing belt, you can continue to pay attention to Mingyi packing belt. If you need pp strapping, please email or leave a message online.
