Every performance of adhesive labels roll
like strength, adhesive properties and the backing paper strength of adhesive labels roll has a certain impact on die cutting quality, so In the selection of adhesive materials and label processing, there should be certain requirements, using high quality materials or the corresponding die-cutting process for improving the label die-cutting quality.
In this paper, a summary is made.based on the actual production problems encountered over the years, it mentioned about how to choose adhesive labels roll material correctly to improve quality of die cutting, we hope it can help label printing enterprises to improve quality of die cutting.
1. Do not use die - cutting paper materials by die - cutting version, because the blade has been worn, it is not suitable for die - cutting film materials.
2. In the process of flat die-cutting, as far as possible to reduce the die-cutting area, especially die-cutting full version of small labels. Die cutting quality is difficult to ensure because of large layout and much blade with high probability of breaking off the mark.
3. Flat die-cutting pad version should to be replaced often, especially after processing a long version, because the cutting mark will affect the quality of the new format label die-cutting.
4. Often check the quality of die-cutting, especially automatic labeling labels, which can avoid mass quality problems. The specific inspection method is to use a signal pen on the bottom paper daub, check the cut mark penetration on bottom paper.
5. Die-cutting the large areas of complex pattern label, you should go to the professional manufacturers to make die-cutting version, so as to ensure the precision of die-cutting.
6. To keep the blade sharp, set up a file to record the use of each die cutting plate, so as to replace the blade in time.
7. To use a small angle of high hardness of the special blade to die - cutting film adhesive labels roll materials, especially PET materials.
8. Pay attention to the label shape and rounded corner design, unreasonable label shape design will cause the edge of the paper fracture and affect the label exhaust speed and quality.
In short, label printing enterprises in the process of die-cutting label products must be familiar with the structure of adhesive labels roll material characteristics, According to the different characteristics of adhesive labels roll materials to choose different die - cutting, so as to improve the quality of die - cutting and reduce waste and save costs.
