We all know that heavy carton packaging is generally produced by bonding seven layers of heavy corrugated board. The cartons made of this kind of corrugated board are very high in both hardness and load-bearing capacity. Being able to have such excellent performance is not only the advantage of material, but also some advantages produced in the production process. Let's take a look at the five points that need to be paid attention to in the bonding of seven layer corrugated board.

1、瓦楞芯纸复合时，涂布胶水会增加瓦楞芯纸含水量，胶黏剂干燥后又要防止瓦楞芯纸脆化，因此选择含水量少、渗透性缓，并易于均匀涂布的瓦楞芯纸复合用胶黏剂非常关键。

1. When the corrugated core paper is compounded, coating glue will increase the water content of the corrugated core paper, and the adhesive will prevent the embrittlement of the corrugated core paper after drying. Therefore, it is very important to choose an adhesive for corrugated core paper compounding that has less water content, slow permeability, and is easy to be evenly coated.

2、在满足复合后黏合强度的前提下，上胶量以尽可能少为原则。

2. On the premise of meeting the bonding strength after composite, the amount of glue should be as small as possible.

3、压瓦楞前，控制好复合后的瓦楞芯纸的湿度也很重要。湿度太大不但影响成型，而且会在复合时引起脱胶;湿度太小，会在瓦楞成型弯曲时使楞峰脆化破裂。

3. Before pressing corrugated, it is also important to control the humidity of the corrugated core paper after lamination. Too much humidity will not only affect the molding, but also cause degumming during compounding; If the humidity is too low, the ridge peak will be brittle and broken when the corrugated molding is bent.

4、七层瓦楞纸板的瓦楞楞型应由制辊企业根据两层瓦楞芯纸和一层胶的厚度专门计算设计，以生产出理想的瓦楞纸板。

4. The corrugated type of seven layer corrugated board should be specially calculated and designed by professional roll making enterprises according to the thickness of two layers of corrugated core paper and one layer of glue, so as to produce an ideal corrugated board.

5、在真空吸附式单面机上加工七层瓦楞纸板时，要注意调节好吸附系统(吸附罩与瓦楞辊的位置、间隙和风量)和加热系统;复合后的瓦楞芯纸要求有更高的温度才能将热量传递到楞峰，满足糊化温度的要求。

5. When processing seven layers of corrugated board on the vacuum adsorption single-sided machine, pay attention to adjusting the adsorption system (the position, gap and air volume between the adsorption cover and the corrugated roller) and the heating system; The composite corrugated core paper requires a higher temperature in order to transfer heat to the corrugated peak and meet the requirements of gelatinization temperature.

加厚的瓦楞芯纸硬度会变大，容易在成型后脱离瓦楞辊，影响涂胶和复合，产生高楞、塌楞、脱胶和“木耳边”等质量问题，所以必须有足够的吸附风量和负压以及加热温度，才能保证在瓦楞纸板成型后顺利涂胶复合。

The thickened corrugated core paper will become harder, and it is easy to separate from the corrugated roller after forming, which will affect the gluing and compounding, resulting in quality problems such as high and low ridges, corrugation, degumming and "ear edge". Therefore, there must be sufficient adsorption air volume, negative pressure and heating temperature to ensure the smooth gluing and compounding after the corrugated board is formed.
