Fourth, quality testing term
1) Dimensional error: The size exceeds the error range specified by the customer or the national standard.
2) High and low levels: High corrugation fluctuations and uneven board thickness, with the difference being out of tolerance.
3) Surface wrinkles: Creases on the surface of corrugated board that can cause printing defects.
4) Collapse: The corrugation is crushed by external forces.
5) Inadequate bonding: Adhesion strength is not enough. Corrugated board is easy to open because of weak adhesion between layers of paper.
6) Insufficient ration: The total amount of cardboard is less than the specified standard.
7) The hardness is not enough: the water content of the board is too large or the physical properties of the raw materials are low, resulting in the low compressive strength and edge pressure strength of the corrugated board.

9) Skew: The pressure line or beer line is not parallel or perpendicular to the pit, the skew of the large box does not exceed 3 turns, and the skew of the small box does not exceed 2 turns.
10) Insufficient material: Corrugated cardboard has more cardboard than corrugated paper.
11) Lucy (pit): Corrugated cardboard corrugated paper exceeds cardboard.
12) Warpage: In the production of corrugated board, variations in the moisture content of the base paper, improper operation, and environmental changes may cause unevenness in the production of paperboard.
13) seesaw phenomenon: refers to the finished corrugated cardboard, in the surface of the paper along the peak and the back of the peak between the back of the concave phenomenon, the shape of the home like a general washboard, also known as scorpion.
14) Foaming: Partial appearance of corrugated paper and corrugated paper cannot be achieved.
15) Indentation is shallow: when the corrugated cardboard is pressed horizontally, the pressure line is shallow due to the pressure being too small, and the flap is difficult to bend.
16) Cardboard Burst: When the corrugated paperboard after crimping is bent, the pressure line breaks, mainly due to the fact that the paperboard is too dry, the surface/inside paper has poor folding resistance, and the pressure line is not properly handled.
