The problem of corrugated cardboard line bursting has seriously plagued many cardboard production and carton processing manufacturers in the world; especially in dry autumn and winter or in low humidity weather, cardboard warping, bursting lines and other problems frequently occur. It will seriously affect the appearance and quality of the corrugated carton, which makes many carton factories annoying. Not only will it seriously affect the quality of the carton and on-time delivery, but also cause the rework or scrap rate to increase significantly, which makes the carton factory suffer big Economic losses!

It is understood that the cardboard warping, burst lines and other problems arise from a number of reasons. In addition to the factors such as raw paper materials, processing technology, equipment, and personnel, there is one more important factor - the water content of corrugated cardboard.

Normally, it is reasonable to control the moisture content of corrugated cardboard between 12-15%; however, the tests have shown that the moisture content of the cardboard coming off the production line is about 8%, and some are even lower. 6% when the weather is dry. So this kind of cardboard is very easy to have problems such as warping and bursting.

This shows that keeping the appropriate moisture content of the corrugated cardboard can effectively reduce the occurrence of warping and bursting of the cardboard. So, how to make the corrugated board can maintain the appropriate moisture content?

Spray humidification system

The spray humidification system can be installed on the different position of the corrugator line to replenish the moisture lost in the production process, making the corrugated cardboard can maintain the appropriate moisture content - 12% to 15%.

• The double-sided machine sprays lining paper at the entrance to add moisture to the lining paper before the paperboard is formed, and solves the problems of bending of the paperboard and burst lines of the lining paper.

• Spray the inner side of the face paper (adhesive side) before the gluing machine. Before the cardboard is formed, add moisture to the face paper to solve the problems of bending on the cardboard and bursting of the face paper.

• Spray the face paper/lining paper before the slitter to add moisture to the cardboard, completely solve the cardboard burst line and delay the cardboard storage time.

• Single-sided machine sprayed tile paper, supplement the moisture of the corrugated paper, increase the flexibility of the corrugated paper, and prevent the corrugated paper from breaking due to drying and poor adhesion.

It works well on BHS/BW Papersystems/FOSBER/AGNATI/HSEIH HISU/MINGWEI/ K&H and other brand corrugators.
