Corrugated cardboard is called corrugated paper, which is made up of wavy corrugated paper (called the center) and liner paper (paper), which is made of flat, stiff cardboard and bonded on one or both sides with adhesive. To increase the degree of cushioning, some are made in duplicate and are mainly used to make corrugated boxes.
The purpose of using corrugated boxes is that they are not only very useful in terms of rationalizing the use of wood resources, but also because they are less expensive than wood boxes of the same size, because they use less than 1/10 of the wood. The manufacturing method is such that a liner paper having a basis weight of 180 to 400 g / m 2 produced by a paperboard paper machine and a corrugated paper roll having a basis weight of 120 to 150 g / m 2 are put on a corrugating machine. A corrugated cardboard is made with a wavy, uniform corrugated cardboard, and at the same time, the corrugated cardboard is made by bonding to the liner paper.
Corrugated cardboard is divided into corrugated cardboard for external packaging and internal packing depending on the application. The process of making a corrugated cardboard box involves first determining a certain box style according to the contents to be packed, then printing the necessary items on the corrugated cardboard surface, cutting it in a sliver, It will be bonded with adhesive tape. Be careful not to create warp on the corrugated cardboard. When assembling, make sure that the bent part is at right angles. The advantage of a corrugated box is that it is light in weight, easy to stack, convenient to carry and store, can be folded, and is not easily damaged by external impact. Uses include food, electrical appliances, machine parts, miscellaneous goods, fruits and vegetables, meat, etc., but they are not suitable for packaging of super heavy cargo.
The basic forms of corrugated boxes are A, B, C, and E, and there are BA, BB and EB corrugated double sided corners. To see in details in our next blog
