Hot melt glue mouth penetration analysis
Publish Time: 2024-06-06
In the paper packaging industry, Hot melt glue mouth has been widely used due to its excellent performance, especially its strong penetration. Penetration is a crucial performance of Hot melt glue mouth in the paper packaging process, which determines whether the glue can fully penetrate into the fiber of the cardboard to achieve a firm bond.
First, let's take a look at the working principle of Hot melt glue mouth. Hot melt glue mouth heats the solid hot melt glue to a molten state through a heating device, and evenly applies the molten glue on the cardboard to be bonded through a nozzle. In this process, the penetration of Hot melt glue mouth plays a key role.
Hot melt glue mouth with strong penetration can ensure that the glue fully penetrates into the fiber of the cardboard and forms a close physical and chemical bond with the cardboard. This combination not only enhances the firmness of the paper packaging, but also improves its waterproof, moisture-proof and wear-resistant properties. At the same time, since the glue can penetrate into the interior of the cardboard, it also reduces the accumulation of glue on the surface of the cardboard, making the appearance of the paper packaging more beautiful.
Specifically, the penetration of Hot melt glue mouth is affected by many factors. First of all, the performance parameters of the glue, such as viscosity and softening point, will affect its penetration ability. Generally speaking, hot melt adhesives with moderate viscosity and low softening point have better penetration. Secondly, process parameters such as glue application amount, glue application speed and glue application pressure will also affect its penetration effect. In practical applications, these process parameters need to be adjusted according to the specific paper packaging materials and requirements to obtain the best penetration effect.
In summary, Hot melt glue mouth plays a very important role in the paper packaging industry. Its strong penetration can ensure that the glue forms a firm bond with the cardboard, and improve the firmness and waterproof and moisture-proof properties of paper packaging. In practical applications, it is necessary to select a suitable Hot melt glue mouth and adjust the appropriate process parameters to obtain the best bonding effect.
