Description

Technical Field

[0001] The utility model belongs to the field of carton industry, and in particular relates to an environmentally friendly and retractable carton. Background Art

[0002] In the carton industry, carton is a common packaging container, usually made of cardboard or corrugated cardboard, used for transporting, storing and protecting goods. In the prior art, the volume of conventional cartons is determined by the size of the paper material itself, and it is difficult to adjust the size of the storage space according to the size of the items stored inside. At the same time, conventional cartons are often packed with tape to seal the cartons. The tape will not only damage the cartons and affect the secondary use of the cartons, but also pollute the environment and cause waste of resources. Therefore, an environmentally friendly and retractable carton is proposed to solve the above problems. Utility Model Content

[0003] In order to overcome the problems that during the use of cartons, conventional cartons are difficult to adjust the size of their storage space and conventional cartons are often sealed with tape, which affects secondary use and is less environmentally friendly.
