[0002] Corrugated cardboard is a multi-layered laminate, consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet," "corrugated paperboard," "corrugated core," or "corrugated base paper") and one layer of cardboard (also known as "boxboard" or "boxboard"). It possesses high mechanical strength, can withstand impacts and drops during handling, and is also lightweight and aesthetically pleasing. With the increasing demand in the corrugated box industry, the development of cardboard box production places increasingly higher demands on cardboard box machinery and equipment. Cutting the cardboard is necessary during the processing of corrugated cardboard.
