Cup paper can be divided into cup base paper, coated cup paper, and paper cup fan. This is a comprehensive and orderly processing flow. We coated the base paper with PE to make a PE coated cup paper. After the next step of cutting, we discarded excess waste edges and turned it into paper cup fan. After printing the paper cup fan and combining them with the bottom of the paper cup, the final paper cup can be made by a professional machine that produces paper cups.
