The shape and structural design of the carton are often determined by the shape characteristics of the packaged goods, so there are many styles and types, such as rectangle, square, polygon, special-shaped carton, cylinder, etc., but the manufacturing process is basically the same, that is, material selection—icon design-template manufacturing–stamping—carton box shaping. If the carton box is divided according to the quantitative paper, it can be divided into three categories: thin carton box, thick carton box and corrugated box. Then I will talk about the characteristics of these three types of cartons.

Carton box, as an indispensable part of modern logistics, bears the important responsibility of packing, maintaining goods and beauty. The physical performance index of carton box becomes the basis of its quality evaluation. Carton box can be recycled to save costs. Carton box can be made into a variety of needs of the style, widely used as food, medicine, electronics and other products sales carton box. Such as large refrigerator packaging carton, air conditioning packaging carton, fresh carton, also have small and exquisite jewelry packaging carton, watch box. Many shopping malls today, including clothing stores, also use cartons. We can see the shadow of paper boxes everywhere in our life.
