Description

Technical Field

[0001] This utility model relates to the field of creasing machine technology, and more specifically, it relates to a creasing machine for corrugated cardboard box processing. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall and double-wall corrugated paperboard. Corrugated boxes are currently the most widely used paper packaging containers, consistently ranking first in usage among various packaging products. Due to their superior performance and good processing properties, corrugated boxes have gradually replaced wooden crates and other transport packaging containers, becoming the mainstay of transport packaging. Corrugated boxes are made from corrugated paperboard through die-cutting, creasing, and stapling or gluing. The quality of the creasing directly affects the quality of the finished cardboard box, thus requiring the use of a creasing machine.
