The properties of pressure-sensitive bonding label materials, such as the strength of the pressure-sensitive adhesive substrate, the characteristics of the adhesive and the strength of the stripping paper, have a certain impact on the die-cutting quality of the label, and select pressure-sensitive adhesive materials and labels. In processing, there should be some requirements to use high-quality materials or the corresponding die-cutting process to improve the quality of label die-cutting.

Through years of practice, the problems encountered in the work are summarized and summarized, and the correct selection of pressure-sensitive adhesive materials is put forward, which effectively improvesProtective film Die-cuttingA few precautions for quality.

First, because the blade is worn out and not suitable for die-cutting, so do not use paper material punchingProtective film Die-cuttingMaterials.

Second, flat die cutting, to minimize the die-cutting area, especially the full version of the small version of the label, because the layout is large, the number of knives, quality is difficult to guarantee.

Third, the planar die-cutting time plate should be replaced frequently, especially for long hours of work, because cutting traces will affect the new layout label die-cutting quality.

Four, flat die cutting, die-cutting force just right, this is the adjustment technology of the master knife, sometimes prefer to cut lighter.

V. Always check the quality of die-cutting, especially automatic labeling. Avoid high quality problems. The specific inspection method is to apply a signal pen on the off-type paper to detect the penetration of the paper cutting.

Six, die-cutting large area of complex label patterns, to professionalDie-cutting processing plantHome production die-cutting version, which can ensure the accuracy of die-cutting.

Seven, to maintain the sharpness of the blade, please create a file to record the use of each die-cutting version, in order to replace the blade in a timely manner. Thin film pressure-sensitive adhesive materials, especially PE materials, with special blade die-cutting, angle.
