There are several other reasons besides adhesive that you need to know about when it comes to the delamination of paste boxes!

The pasting process is an essential operation in the formation of color boxes, and the most common quality issue encountered is delamination. While most people attribute this to adhesive problems, there are actually many factors that can affect the adhesion of paste boxes.

There are various factors that influence the adhesion of paste boxes, including paper quality, adhesive, pasting process, and environmental conditions, all of which are crucial.

The density, smoothness, moisture content, and surface treatment of the paper directly impact the adhesion of paste boxes. Poor-quality paper is prone to cracking or delamination after pasting, thus affecting product quality.

Additionally, the selection and use of adhesive are significant factors affecting the adhesion of paste boxes. The viscosity, drying speed, curing time, and compatibility with paper of the adhesive directly affect the adhesion of paste boxes. Improper viscosity or insufficient curing time of the adhesive can also lead to delamination of paste boxes.

Furthermore, the proper operation and technical proficiency in the pasting process are key factors influencing the adhesion of paste boxes. Improper operations or unreasonable process flow often result in unstable paste box formation quality and issues like delamination. Therefore, enhancing operational standards and improving staff technical skills are crucial for ensuring the adhesion of paste boxes.

Lastly, environmental factors also impact the adhesion of paste boxes. Changes in temperature, humidity, and other environmental parameters directly affect the coating effect and drying speed of the adhesive, thereby influencing the adhesion of paste boxes. Therefore, ensuring that the production environment meets requirements is essential for maintaining the adhesion of paste boxes.

In conclusion, there are various factors that affect the adhesion of paste boxes, and it is necessary to consider paper quality, adhesive selection and use, proper pasting process operations, and production environment to effectively address delamination issues and improve product quality.
