The main reasons for degumming and blistering on the edge of gift boxes

The main reasons for degumming and blistering on the edge of common gift boxes are as follows:

, if the problem of artificial production is excluded, then the glue is mixed with too much water and the concentration is not enough, which will cause the adhesion to be weak.

, if there is no problem with the glue, then during the production process of the gift box, the glue is not applied evenly or the drying time is too long.

Third, the glue is not applied evenly, resulting in no tight bonding between the cardboards.

Solution:

1. Test the glue before the production of the gift box. It is better if the thumb and index finger are sticky (of course, the material of the gift box is different, and the glue used is also different).

2. In the process of making the gift box, pay attention to the uniformity of the glue, and use a semi-automatic foaming machine or a scraper to carry out a carpet treatment on the surface of the gift box to ensure that the glue can reach the tissue paper.

3. Reasonably grasp the drying time. After drying, use external force to tear the edge of the tissue paper to see if it is destructive. If it is, the glue is sufficient to be a qualified product and will not be degummed in the future. If it is not, it is falsely sticky, and the glue or method should be adjusted.
