Corrugated cardboard is generally divided into single-sided corrugated cardboard, three-layer corrugated cardboard, five layer corrugated cardboard and seven layer BCE corrugated cardboard. Single sided corrugated board is made of one piece of paper and one piece of corrugated paper. Three layer corrugated board, also known as single corrugated board, is formed by pasting corrugated paper between a sheet of paper and a sheet of paper. Five layer corrugated board is also called double-sided corrugated board, which is located between panel paper, core paper and inner paper. It is formed by pasting two pieces of corrugated paper; 7-layer BCE corrugated board is also called triple corrugated board. It is formed by pasting three pieces of corrugated paper between paper, core paper and backing paper.
Ordinary customers choose single corrugated board or double corrugated board to make corrugated boxes. The cost of cardboard boxes is reduced. The use of single corrugated boxes accounts for about 90%, while the use of double corrugated boxes accounts for about 10%. Among corrugated boxes, double watt boxes account for about 80% of the total, and single watt boxes account for about 20%. This requires corrugated box manufacturers to actively guide customers, reasonably select corrugated boxes, avoid excessive packaging, and cause unnecessary waste of resources.
The types of 4-layer BE corrugated board are generally divided into single-sided 4-layer BE corrugated board, 3-layer 4-layer BE corrugated board, 5-layer 4-layer BE corrugated board and 7-layer 4-layer BE corrugated board; The three-layer 4-layer BE corrugated board, also known as single 4-layer BE corrugated board, is formed by sticking a piece of corrugated paper between a piece of face paper and a piece of lining paper; Five layer and four layer BE corrugated board, also called double four layer BE corrugated board, is formed by sticking two pieces of corrugated paper between face paper, core paper and lining paper; Seven layer four layer BE corrugated board is also called three four layer BE corrugated board. It is formed by sticking three pieces of corrugated paper between face paper, core paper and lining paper.
General customers choose single 4-layer BE corrugated board or double 4-layer BE corrugated board to make corrugated boxes. In Europe and the United States, the production of corrugated boxes has entered the quantitative analysis, reducing the cost of cardboard boxes. The use of corrugated boxes with single tiles accounts for about 90%, and that of corrugated boxes with double tiles accounts for about 10%. In China, double corrugated boxes account for about 80% of the total, and single corrugated boxes account for about 20%. This requires corrugated box manufacturers to actively guide customers, reasonably select 4-layer BE corrugated board, and avoid excessive packaging, resulting in unnecessary waste of resources.
The proportion of carton length (L), width (W) and height (H).
Edge compression strength of color printing packaging carton: the horizontal ring compression value of corrugated paper, the thickness of paperboard and the bonding quality all have a certain impact on its edge compression strength, so it is necessary to realize a large increase in its pressure resistance from the base paper to the paperboard.
Relevant process control in the process from color printing packaging carton board to finished carton products: that is, how to realize the small impairment of its pressure resistance in the process from cardboard to carton.
