UDN participated in the PACKCON2023 in Shanghai during 12th July to 14th July and was very glad that our innovative tubes attracted many clients. Round Tube, Rolling Tube, One-piece Tube and Tube in Tube were the most popular ones. See you next time! #udnpack #udn #PACKCON2023 #Roundtube #Rollingtube #onepiecetube #tubeintube #Shanghaiexhibition
