Die cutting encounters "flying labels"? The most likely reasons are these!
In the daily production process of self-adhesive label, die-cutting failure is a common failure that affects production efficiency. The main reasons for die-cutting flying label are:
NO.1. Excessive fluidity of glue
If the fluidity of the glue is too strong, and there is no time to discharge the waste after die cutting, the cut glue will flow back together again, forming a glue drawing,This glue wire drawing also sticks the two sides of the material that has been cut together, so it is easy to cause the label to be taken up when the waste is discharged.
NO.2. Waste discharge angle is too small
During waste disposal, the waste disposal edge will form an angle with the material, which is called the waste disposal angle. If this angle is too small, it is easy to cause the label to be pulled up by the waste side.
NO.3. Environmental impact
The release force of hot-melt adhesive self-adhesive material is greatly affected by temperature, and its release force will be greatly reduced under the temperature below 10 ℃. It is easy to cause labels to be taken up during die-cutting and waste disposal.
Therefore, when processing hot melt adhesive adhesive materials in winter, pay attention to the indoor temperature and try to ensure that the temperature is above 15℃.
