Background

The carton is generally composed of an upper bottom cover, a lower bottom cover, an inner surrounding strip and a panel, and is formed by bonding in a specific method. Cartons and cartons are common devices for storing articles in production and life, and most of the earliest cartons are produced by manual work. With the development of science and technology, various process flows are gradually changed into automatic production, and the production process of the paper box is also manually gradually changed into semi-automation and automation. Most of the existing paper box production adopts a die cutting process to form a paper board which is a front body of the paper box, and then the paper board is formed into the paper box. The production process of the paper box directly adopts the purchased paper boards to process and cut, so that the production cost of the paper box is undoubtedly greatly increased.
