In recent years, with the improvement of automation of packaging enterprises, more and more manual paste boxes have been replaced by full-automatic box making machines, not only the production efficiency has been greatly improved, but also the product quality has made a qualitative leap. However, in the actual production process, we often find some quality problems, such as carton deformation, wrinkling, blistering, poor adhesion and so on, which lead to high scrap rate and seriously affect the efficiency of the paper box machine factory. Among them, "bubbling" is the most prominent phenomenon, that is, bubbles appear at the bottom of the box and around the box. In this paper, the author takes "bubbling" as an example to analyze and discuss the influencing factors and solutions from the perspective of production.

胶固含量

胶水固含量太低，完成后第二天盒子容易起泡。这是因为胶水中水分过多，影响了胶水的粘度，降低了胶水的粘度。因此，在生产过程中应严格控制胶水的固含量，一般应达到55%左右。

环境温度和湿度

夏季车间温度过高、湿度过高，会导致胶水的凝结速度和干燥速度过慢，制作的盒子容易起泡。但在寒冷的冬季，由于室温较低，会出现纸张尚未粘贴、胶水凝固的现象。如果错过了胶水的最佳粘合期，很容易造成盒体起泡。因此，必须严格控制环境的温湿度。

纸张表面处理工艺

纸张的表面处理不当也会导致盒子起泡。如果面纸有烫印工艺，如果烫印时压力过大，会造成烫印部位的纸张不均匀，凹面部分很难达到胶水，盒体会起泡。当纸张需要烫印时，需要控制烫印压力和温度，以保证纸张的平整度。

当然，影响包装盒起泡的因素很多，其中有些因素在实际生产过程中是不可避免的。随着技术的发展，全自动泡罩机对纸箱的起泡效果良好。
