Raw material cost, production process and other reasons.
1, the cost of raw materials: white resin ribbons use raw materials are high-grade resin, the cost of these resins is higher. In contrast, the raw material cost of black ribbon is lower.
2, the production process: white resin ribbon production process is relatively complex, requiring the use of more sophisticated production equipment and technology. The production process for black ribbons is relatively simple and requires a lower level of equipment and technology.
