How to distinguish a good packing strap? The experienced Shaanxi packing belt manufacturers share the simple identification method for everyone, please see below:
Color: Anything that is transparent is better than opaque, no matter what color it is.
Gloss: Gloss is better than non-gloss. The so-called gloss is the material itself, which is the color of the surface of the material.
Smell: Ignite with a lighter, blow it out after 3 seconds, smell its scent, and discern the difference between it and new material PP. Pay attention to the fact that some color toners emit a larger taste, which will mask PP (PP regeneration Ingredients).
Wire drawing: After blowing out the fire, use an iron object to quickly contact the melt, and then quickly open it to see if the wire formation is uniform. If it is uniform, it is good. Pull it a few times to overlap the wire and pull it again. To see if it has elasticity, can it be pulled open again and continuously, what is unbroken or broken after a certain interval is good.
Burning with fire: It is not good to have black smoke or drip from the melt quickly during the burning process.
Use your teeth to bite: first experience the strength of the new or recycled material yourself, and then compare it, the relatively soft is not the good material.
Look at the section of the incision: the section is rough and not shiny, and the quality of the material is poor.
