wave rules
Wave rule is a knife that can cut the safe edges of cardboard and corrugated boxes to prevent injury when handling boxes or paper.
You may have suffered a finger cut while handling a paper or box.
The cutting speed causes small burns to the wound, and the cross section of the paper is not smooth, but has a saw-like rough shape, making the cut more open and painful than cutting it.
Use steel rule to prevent this.
If you have any questions about the packaging, please use our website.
