The corrugated cardboard of the Suzhou corrugated box manufacturer is made by bonding face paper, lining paper, core paper corrugated paper processed into corrugated corrugated. According to the needs of commodity packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer corrugated cardboard.

Different corrugated shapes of corrugated cardboard Kunshan corrugated box manufacturers have different functions. Even if the same quality of face paper lining paper are used, due to the difference in corrugated shape, the performance of the corrugated board formed will be different. There are four types of flute shapes commonly used in the world. They are Type A, Type C, Type B Type E. Their technical indicators requirements are shown in Table 1. The corrugated board made of A-type flute has better cushioning properties is full of certain elasticity, the C-type flute is next to the A-type flute. But the stiffness impact resistance are better than A-shaped flute; B-shaped flute has a large arrangement density, the made corrugated board has a flat surface, high bearing pressure, suitable for printing; E-shaped flute is thin dense, showing its rigidity. strength.

The main difference between container non-container lies in the outer diameter, which is closely related to the type of corrugation. The following table lists the relationship among carton inner diameter specifications, manufacturing specifications, outer diameter specifications in detail:

Measuring method of corrugated box manufacturing size

The manufacturing size of the carton made by Suzhou carton manufacturer is the blank size when making the carton. The manufacturing size is based on the pressure line on the unfolded box blank. The creasing roller on the slitter presses out a groove at the pressure line position, the pressure line is the center line of the groove. The distance between the two pressing lines is the manufacturing size. The conversion of manufacturing dimensions to inner outer diameters can be made quickly through Table 2, but they also have their own measurement methods.

Corrugated boxes are divided into single double spells in the manufacturing process

Single piece is a one-page forming box, which is generally used for cartons with a small circumference; double-piece is also called a two-page box. Some cartons have too large circumferences have to use two pieces of blanks to piece together a carton, but sometimes the carton factory uses the production The remaining material cut in the process will also be used to piece together a carton of too large a size with two pieces, even four pieces sometimes. Compared with the one-page box, the two-page box has one more joint, so there are some slight differences in the area calculation of the two.

Connector wire return

The manufacturing size of the carton joints of the Kunshan carton manufacturer is determined according to the number of corrugated layers the level of production technology. The single corrugated cardboard is 35 ~ 40mm, the double corrugated cardboard is 45 ~ 50mm, the three corrugated cardboard is 50mm.

When calculating the unfolded area of the carton, the loss of wire waste during the manufacturing process must be considered. The size of the wire waste is determined by the number of cardboard layers, generally 20 ~ 40mm.
