Carton production process

As a common packaging material, paper boxes are widely used in various fields, such as food, medicine, electronic products and other industries. Carton production process usually includes paper selection, printing, die-cutting, folding, bonding and other links.

First of all, the production of cartons requires the selection of appropriate paper. Different types of paper are suitable for different cartons, such as food boxes often use food-grade paper, and electronic product boxes need paper with shock-proof properties. In general, the thickness and texture of the paper will also be selected according to the use of the box. After the paper is selected, the paper is fed into the printing process.

Printing is a crucial step in carton production. Carton printing usually uses color printing technology to make the appearance of the carton more beautiful. The content of printing can be text, pattern or image, and it is designed and printed according to customer needs. After printing, the paper will enter the die cutting process.

Die cutting is the process of cutting paper according to a specific shape. Die cutting can be customized according to the size and shape of the carton. The die cutting process is usually carried out using a laser or mechanical mold to ensure the accuracy of the size and shape of the carton. After the die cutting is completed, the paper will enter the folding process.

Folding is the process of folding the die-cut paper according to the predetermined folding line. The design of the folding line needs to fully consider the foldability of the paper and the stability of the carton. The reasonable design of the folding line directly affects the appearance and service life of the carton. When the folding is complete, the paper will enter the bonding phase.

Adhesion is the folding of the paper by glue or hot melt adhesive process adhesion methods have two kinds of manual adhesion and mechanical adhesion. Manual bonding is usually suitable for small batch production, while mechanical bonding is suitable for large-scale production. After the glue is completed, the carton will enter the packaging process.

Packaging is the production of good cartons in accordance with a certain number of packaging and sealing process packaging can protect the carton from moisture, pollution and damage. At the same time, the design of the packaging should also meet the market demand, easy to handle and sell. After the packaging is complete, the cartons can be delivered to the customer or stored in the warehouse.

In summary, the carton production process includes paper selection, printing, die-cutting, folding and bonding and packaging. Each link needs to be closely coordinated to ensure that the quality and appearance of the carton meet customer needs. The production process of the carton requires not only efficient production equipment, but also experienced workers and the support of the quality management system.
