Process flow of corrugated board production

Process flow:

(1) Cutting a horizontal pressure line, slotting, printing and joining;

(2) Cutting, horizontal pressing line-slitting, vertical pressing line-printing-joining;

(3) Cutting, horizontal pressing line—printing, slitting, and vertical pressing line—joining;

(4) Printing, slitting, and longitudinal pressing line are joined together.

(5) Printing, slitting, longitudinal pressing and joining.

Corrugated cardboard is made into corrugated cardboard boxes after die-cutting, creasing, nailing or gluing. Corrugated box is one of the most widely used packaging products, and the amount used has always been the first of various packaging products. Including calcium plastic corrugated boxes.

Corrugated boxes gradually replaced wooden boxes and other transport packaging containers with their superior use performance and good processing properties, and became the main force of transport packaging. In addition to protecting commodities, facilitating storage and transportation, it also plays a role in beautifying and promoting commodities. Corrugated boxes are environmentally friendly products, which are good for environmental protection and convenient for loading, unloading and transportation.

Corrugated board classification

2. Classification according to the number of base paper layers: two-layer cardboard, three-layer cardboard, four-layer cardboard, five-layer cardboard, seven-layer cardboard, etc.;

3. Classified by flute shape: U-shape, V-shape, UV-shape; UV-shape is commonly used in the market.

Principles of Corrugated Board Design Method:

The packaging structure design is based on the actual conditions of packaging and production, based on scientific principles to design the external structure and internal accessories of the packaging. The design must ensure that the structure has sufficient strength, hardness and ability to withstand other environments.

Qualified carton products start from the correct structural design. The designer must not only truly understand the customer’s intention, but also be familiar with the subsequent processing technology. Only in this way can the customer’s intentions be transformed into qualified products and the subsequent processing can be ensured smoothly.

The designer must understand the nature, shape, size, weight of the contents, the arrangement, transportation, and stacking methods of the contents, the storage environment, transportation routes and time of the contents, the carton type and production materials before the design starts. information.
