If the product appearance is rough, having forming defects, color impurities, printing quality is poor, it is better not to choose.
2. Smell — it is better not to use the product that has odors. The pungent odor will harm the human respiratory system. The main reason plastic products have odors is the use of recycled materials and inferior additives.

Plastic pipe caps are made of plastic as the main raw material, and the development direction of plastics can be summarized in two aspects. One is to improve performance, that is, to modify existing varieties by various methods to improve its comprehensive performance; second, to develop functions, that is, to develop polymer materials with physical functions such as light, electricity, and magnetism so that plastics can have Photoelectric effect, thermoelectric effect, piezoelectric effect, etc.
