The so-called corrugated board is a simple, uncomplicated packaging material that is used in everyday industry. Its main differences are low weight and high physical parameters. It is one of the most widespread materials around the world, used as plain packaging. The main disadvantage is that it permeates moisture very well.
This material usually consists of 3 layers: one layer of paper and two flat layers of cardboard. This combination makes corrugated board particularly tough. Also, in order to increase the physical properties of the material, 5- and 7-layer corrugated cardboard is used. One of the companies providing the opportunity to receive corrugated cardboard from a warehouse in Moscow is the Fakel company.
Corrugated cardboard is also processed and further, it is used to create a container. The main web of material is cut into blanks of the required size, and then the valves are die-cut. Typically, these boxes are printed with images consisting of several colors. One of the most common types of containers is a four-valve box.
By structure and physical. The properties of corrugated board are divided into different classes, which are marked with a letter that indicates the class number and the number of layers. Typically, in everyday industry, 3-layer grades T-21, T-22 and T-23 are used. Corrugated board consisting of five layers is designated by the letter P, and which consists of two layers - D.
The production of corrugated board has not always been so large. After all, only over time, the speed of production of this material increased very quickly. At the end of the 20th century, the production speed was 100 meters per minute. And nowadays it reaches 300 meters per minute. This is very fast and rapid growth.
