Our factories are all located in cities close to our customers, with convenient transportation. Cities like Shanghai, Jiaxing and Hangzhou are particularly close to the ports and are also convenient for export.
The factories have all been meticulously designed. The Shanghai factory is small but highly efficient, suitable for rapid response and sample production. The Jiaxing factory mainly focuses on coating of self-adhesive materials and custom printing of labels. The Hangzhou factory is the largest, mainly producing standard thermal-sensitive blank and coated paper blank labels. It is also equipped with a modern automated warehouse and automatic conveyor belts, facilitating our online business. The factories in Thailand and Vietnam are located in industrial parks that are closest to our customer base.
The distances between the three factories in China are about one hour’s drive, facilitating logistics and communication between personnel. Here, we have also met many customers from various countries. It is also very close to the Shanghai Exhibition Center.
