Something of corrugated paper you need to know

In daily life, corrugated paper is a very common product; it is widely used in transport packaging, disposable packaging containers, digital cameras, and other micro-electrical products packaging.

Corrugated board is made of face paper, inner paper, core paper, and the corrugated paper processed into corrugated by bonding. According to the needs of commodity packaging, the corrugated board can be processed into a single-sided corrugated board, three-layer corrugated board, five-layer, seven-layer, eleven-layer corrugated board.

Different corrugated shapes of corrugated board, glued corrugated board function is also different. Even if the same quality of face paper and inner paper are used, the performance of corrugated board made of tungsten carbide slitting knives is different due to the difference of corrugated shape. There are four kinds of corrugation in the world, they are A-shaped, C-shaped, B-shaped, and E-shaped.

The corrugated board made of A-type corrugated board has better cushioning and elasticity and the C-shaped corrugated board is the second. However, the stiffness and impact resistance are better than those of type A; the arrangement density of type B is large, and the corrugated board made of it has smooth surface and high-pressure bearing capacity, which is suitable for printing; the E-shaped corrugated board shows its rigidity and strength because of its thin and dense.

The difference between container and non container mainly lies in outer diameter, which is closely related to corrugated type.

Measuring method for manufacturing dimensions of corrugated box

The manufacturing size of the carton is the cutting size when making the carton. The manufacturing dimension is measured by the pressing line on the unfolded blank. The indentation roller on the slitting machine presses out a groove at the pressing line position, and the indentation line is the center line of the groove. The distance between the two pressure lines is the manufacturing dimension.

Single sheet is one sheet forming box, which is generally used for cartons with smaller circumference; double splicing is also known as two sheet box. Some cartons have too large circumference, so they have to use two pieces of blank to make a carton. But sometimes, in order to make use of the surplus materials cut in the production process, the carton factory will also use two pieces to make a small size carton, and sometimes even use four pieces. Compared with one sheet box, two sheet box has one more joint, so there are some slight differences in the area calculation between the two.
