The use of ribbon printing bar codes in logistics transportation and warehousing management is particularly common. They contain useful information such as inventory quantity and inventory area. At the same time, with clear print quality and wear-resistant and scratch-resistant performance, they ensure the accuracy and timeliness of product tracking, which greatly improves work efficiency. Warehouse labels are mainly to ensure the quality and traceability of the assembly line products to the warehouse shelves. Such labels must ensure the clarity during use, so that they can be clearly displayed by the naked eye or during scanning. They can be mainly applied to warehouse shelves, Out-of-warehouse markings, turnover markings, etc. The warehouse transit label may cause friction during storage and handling, and may damage the label content and cause no traceability.
