On May 27-29, China (Qingdao) International Medical Equipment Expo was held in Qingdao International Convention and Exhibition Center, and the booth number of QDBOSS was 1D55. We used polyester fiber acoustic panel to print advertisements to promote our melt blown fabric. The epidemic in the past year or so has had a major impact on global economic development, and QDBOSS hopes to make its own contribution to the global fight against the epidemic. Friends are welcome to inquire about our acoustic panels and melt blown fabric.
