How to choose the raw materials for plastic placemats?

         We all know that plastic placemats are blow-molded and woven with plastic particles, so how should we choose the raw materials for the production of plastic placemats? Let's briefly talk with you. We need to learn to distinguish from the product color gloss, hardness and other aspects. First, let's take a look at the brightness of the product. Generally, products with good whiteness are of high quality.

         Then we can use teeth to test the hardness of the product. Products with high hardness are of good quality, and some soft particles cannot be ordered. Furthermore, we can also distinguish the quality of the product by looking at the floating of the particles. We can put plastic particles in the water, and those that are submerged in water have quality problems, and those that are floating on the water are good quality plastic particles. These are some good methods to identify the quality of PP plastic particles. At the same time, these methods are relatively simple to use and do not take too much time. It is relatively feasible.
