[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single corrugated paperboard and double corrugated paperboard. It is an important production material for producing packaging cartons. It has high requirements for the folding resistance of noodle paper. The current means of testing folding resistance are backward and cannot complete the test and guide production in real time. The patent document with publication number CN 106483026 A discloses a paper folding resistance testing device, including a clamping part and a rotating part.
