Plastic particles are divided into new material and recycled material. The new material is extracted and decomposed from petroleum, and the recycled material is recycled and granulated for plastic products.

The color of the new material is transparent or semi-transparent milky white, and the color of the return material is varied, often black. In order to increase the color diversity of woven cloth, some dyes are usually added, also known as master color.

The color of new material products is bright and shiny, and the return material is dark reflective fuzzy. The new material feels smooth, and the return material has a frosty feeling. In the professional tensile test, the return material has low tensile strength and is easy to fracture.
