The first is the thickness and thickness uniformity, and the second is the fiber structure.

Among them, the thickness and uniformity of the off-type paper is the most important, especially when round die-cutting, because the size of the die-cutting roller is determined by the thickness of the off-type paper, if the thickness of the off-type paper is not uniform, The blade will cut through or can not cut off the paper, causing trouble for the waste disposal process.

The fiber structure of the Glaxin off-type paper mainly affects the die-cutting speed for circular die-cutting, because the strength of the fiber directly affects the rate of discharge fracture. The faster the speed, the greater the pull force, and the easier the disposal. If the material itself is strong, the die-cutting speed can be increased. However, the fiber structure has little effect on the die-cutting quality for the slower flat pressure die-cutting.

In addition, the toughness and fracture resistance of the fiber have a great influence on the die-cutting quality, and the die-cutting of the fiber with good toughness may not be a problem on equipment with low accuracy, but if the fiber of the die-cutting paper is brittle, The toughness is poor. It can only be done on equipment with high precision and good die-cutting quality. This shows that the equipment accuracy is also one of the factors that affect the die-cutting quality.
