Experience sharing on the die-cutting process of protective film production

    The performance of pressuresensitive adhesive label materials, such as the strength of the pressuresensitive adhesive substrate, the characteristics of the adhesive, and the strength of the release paper, has a certain impact on the diecutting quality of the label, and the selection of pressuresensitive adhesive materials and labels. In processing, there should be some require

ments to use high-quality materials or corresponding die-

cutting processes to improve the quality of label die-cutting.

9759彩票集团Through years of practice, the problems encountered in the work have been summarized and summarized, and several precautions have been proposed to correctly select pressure-sensitive adhesive materials and effectively improve the quality of protective film die-cutting.

1、 Due to the worn blades and unsuitability for die-cutting, do not use paper like materials for punching protective film die-cutting materials.

2、 Flat die cutting should minimize the die-cutting area as much as possible, especially for the complete version of the small label, as the layout is large, the number of knives is in rows, and the quality is difficult to guarantee.

3、 The flat die-cutting time board should be replaced frequently, especially for long-term work, as cutting marks can affect the die-cutting quality of new layout labels.

4、 Flat die cutting, with just the right cutting force, is an adjustment technique for the main blade, sometimes preferring shallower cuts.

9759彩票集团5、 Always check the quality of die-cutting, especially automatic labeling. Avoid high-quality issues. The specific inspection method is to apply a signal pen on the release paper to detect the penetration of the cut paper.

9759彩票集团6、 Die cut large and complex label patterns, and provide professional die-cutting manufacturers with die-cutting plates to ensure the accuracy of die-cutting.

9759彩票集团7、 To maintain the sharpness of the blade, create a file that records the usage of each die-cutting version for timely blade replacement. Thin film pressure-sensitive adhesive materials, especially PE materials, are die cut with special blades at an angle of.
