Development status:

With the rapid development of the social economy and the rise of the IT industry, humanity has entered the era of knowledge economy. People's contact and communication have rapidly shifted from being mainly through telephone, telegram, and letter to being mainly through the internet, thus greatly accelerating the speed of information transmission and sharing. Undoubtedly, the mail, which has long been the main way for people to convey information and communicate emotions, is facing challenges, and the postal industry has also undergone changes. With the advent of the information age, the delivery of letters or the mailing of items has evolved from the previous single and time-consuming ordinary mail to express mail, and then to the well-known global postal express delivery today. The development of multiple delivery methods has greatly accelerated the speed of delivery, and the delivery volume has also greatly increased. Whether in the past, present or future of the postal industry, paper containers used as carriers for the postal industry have played an indispensable role and have developed with the development of the postal industry.
