In the production process of paper products, hot melt glue is widely used in packaging, printing and other fields as an efficient and environmentally friendly adhesive. However, paper products of different materials and thicknesses have different requirements for the gluing mode of hot melt glue. Therefore, it is crucial to reasonably adjust the gluing mode of Hot melt glue mouth to ensure the bonding quality and production efficiency of paper products.
For paper products with thinner paper and smooth surface, such as coated paper, offset paper, etc., the gluing mode of Hot melt glue mouth should be adjusted to dot or line. This gluing method can reduce the amount of glue and avoid deformation or wrinkling of paper due to excessive glue. At the same time, dot or line gluing can also improve the bonding efficiency and ensure the stable operation of paper products on high-speed production lines.
For paper products with thicker paper and rough surface, such as kraft paper, corrugated paper, etc., the gluing mode of Hot melt glue mouth needs to be adjusted to surface or spray. This gluing method can ensure that the glue fully covers the surface of the paper and improve the bonding strength. Surface or spray-like gluing can also increase the friction between papers, making paper products less likely to loosen during stacking and transportation.
In addition to considering the material and thickness of paper products, attention should also be paid to the adjustment of parameters such as the model, gluing speed, and temperature of the Hot melt glue mouth. Different models of Hot melt glue mouth have different gluing effects and should be selected according to actual production needs. At the same time, the gluing speed and temperature also directly affect the viscosity and fluidity of the glue, which need to be reasonably adjusted according to the material and thickness of paper products.
In summary, adjusting the gluing mode of the Hot melt glue mouth according to the material and thickness of paper products is the key to ensuring the bonding quality and production efficiency of paper products. In the actual production process, it is also necessary to flexibly adjust various parameters in combination with the actual situation of the production line to achieve the best gluing effect. With the continuous advancement of technology, the gluing mode of the Hot melt glue mouth will be more intelligent and automated in the future, bringing more convenience to the production of paper products.
