Plastics are generally divided into several levels, what is the difference between different grades?
Level 1: Spout, scrap, product scrap. All materials that can be directly processed on the machine without granulation after pulverization. The price is around 85% of the original price.
Level 2: After manual selection, it can be turned into a first grade material after separation and cleaning. Or it can be successful directly after one granulation. Such as clean flowers and miscellaneous materials. The price is 75% of the original price.
Level 3: Manual separation + selection + cleaning + addition of additives + granulation is required to achieve the required materials. The price is 60% of the original price.
Level 4: Waste material. Washing is also not clean, and the points are not clear. As the saying goes: "The taste is tasteless, and it is a pity to abandon it." The price is 35% of the original price.
