How To Solve Paper Gift Bags With Flat Paper Handles High And Low Problem?

How to solve Paper Gift Bags With Flat Paper Handles "high and low" problem?

"High corrugated" refers to the fully formed corrugated, that is, the corrugated height meets the standard requirements or is consistent with the teeth depth of the corrugated roll; And "low corrugated" is not fully formed corrugated, its corrugated height is usually lower than the standard value or lower than the tooth depth of corrugated roll. When the core paper is rolled and bonded with the inner paper, high and low corrugator exist at the same time, called "high and low corrugator".

Low corrugation is one of the reasons that affect the quality of Paper Gift Bags With Flat Paper Handles. Because the height of the low corrugation is small and the adhesion with the surface paper is poor or not adhered to, the bonding strength of the cardboard is affected, and the edge pressure strength and pressure strength are decreased. The surface of face paper is uneven and affects the appearance and printing effect.

The causes and solutions of high and low angst are as follows:

1, corrugated roll is not parallel, both ends of the bearing wear, corrugated roll vibration in high speed operation. Should check and adjust the parallelism of the corrugated roll, adjust the bearing clearance or replace the bearing, reduce the speed to avoid the resonance zone.

2, the pressure between the corrugated roller is insufficient, should increase the pressure.

3. There are waste paper or other impurities in the tooth groove of corrugated roll. Impurities should be removed.

4, corrugated core paper moisture content is too high or too low will affect corrugated molding, too wet should increase the preheating area, too dry should increase the amount of spray.

5, corrugated core paper reel is not round, running rotation is not uniform, need to increase the tension or replace the base paper.
