We summarized the release film problems encountered in die- cutting and proposed several precautions for selecting pressure sensitive adhesive materials.

1、 Do not use a die-cutting board made of die-cutting paper material, as the blade is worn and not suitable for die-cutting film.

2、 When flat pressing and cutting, try to reduce the die-cutting area as much as possible, especially for full size small labels, as the layout is large, there are many knife arrangements, and the quality is difficult to guarantee.

3、 When cutting flat dies, it is necessary to frequently replace the pad plate, especially when processing long plates, as cutting can affect the quality of the new label's die-cutting.

4、 When flat pressing and die-cutting, the die-cutting force should be just right. This is the knife adjustment technique of the blue release film manufacturer, and sometimes they prefer to cut shallower.

5、 Regularly check the quality of mold cutting, especially the labeling of automatic labels. To avoid a large number of quality issues. The specific inspection method is to apply a signal pen to the release paper to detect the penetration of cut marks on the release paper.

6、 Labels with large die-cutting area and complex patterns should be produced by professional manufacturers to ensure die-cutting accuracy.

7、 Keep the blades sharp, establish records, and record the usage of each mold cutting version for timely blade replacement. Use special blade die-cutting film pressure sensitive adhesive materials with small angles and high hardness, especially PE materials.

The technology of die-cutting release film is crucial. If not taken seriously, it will affect the integrity of the release membrane. So I hope everyone can adopt the key points of die-cutting technology mentioned above.
