The die-cutting performance of self-adhesive coated paper mainly depends on its material characteristics, die-cutting methods, die-cutting tools and die-cutting equipment accuracy and other factors. The following is a detailed analysis of the die-cutting performance of self-adhesive coated paper:
First, the impact of material characteristics on die-cutting performance
1.Surface gloss and smoothness: Self-adhesive coated paper usually has a higher surface gloss and smoothness, which helps the die-cutting tool move more smoothly on the paper, reducing cutting resistance and wear, thereby improving die-cutting accuracy and efficiency.
2.Thickness and strength: the thickness and strength of self-adhesive coated paper are moderate, neither too soft nor too hard, which makes it possible to maintain good stiffness and stability in the die-cutting process, and is not easy to deformation or fracture.
3.Adhesive layer: The adhesive layer on the self-adhesive coated paper also has a certain impact on the die-cutting performance. If the adhesive layer is too thick or too sticky, it may increase the difficulty of die-cutting, resulting in continuous cutting or difficult separation of the label after cutting. Therefore, when selecting self-adhesive coated paper, it is necessary to consider whether the performance of the adhesive layer is suitable for die-cutting requirements.
Second, the impact of die cutting mode on die cutting performance
1.Flat stamping die cutting: flat stamping die cutting method is suitable for small batch, multiple varieties of self-adhesive label production. The die-cutting precision is high, but the speed is relatively slow. In the die-cutting process, it is necessary to ensure that the die-cutting plate is smooth and high precision to avoid problems such as cutting through the bottom paper and continuous surface material.
2.Circular die cutting: circular die cutting is suitable for the production of self-adhesive labels in large quantities and continuous production. This method has high die cutting speed, high precision and can reduce waste. In the die cutting process, it is necessary to ensure that the line contact pressure of the die cutter and the bottom roller is consistent to maintain the stability of the die cutting quality.
Third, the impact of die cutting tools on die cutting performance
1.Tool material and hardness: The material and hardness of the die-cutting tool directly affect its wear resistance and service life. For self-adhesive coated paper, the blade is usually selected after hardness treatment to ensure that the sharp edge and stable cutting performance can be maintained during the die-cutting process.
2.Tool Angle: The Angle of the die cutting tool is also one of the important factors affecting the die cutting performance. Generally speaking, the smaller and sharper the blade Angle, the easier it is to cut through the self-adhesive coated paper. However, the choice of specific Angle needs to be comprehensively considered according to the thickness, strength and die-cutting requirements of the self-adhesive material.
Fourth, the impact of die cutting equipment accuracy on die cutting performance
The precision of die-cutting equipment directly affects the die-cutting quality of self-adhesive coated paper. The high-precision die cutting equipment can ensure the precise match between the die cutting plate and the die cutting knife, reducing errors and waste. At the same time, the stability of the equipment is also one of the important factors to ensure the quality of die cutting. In the die-cutting process, it is necessary to ensure that the equipment runs smoothly and the tension is constant to avoid problems such as label deformation and fracture.
In summary, the die-cutting performance of self-adhesive coated paper is affected by many factors. In actual production, it is necessary to select the appropriate die-cutting method, die-cutting tool and die-cutting equipment according to the specific requirements and conditions, and strictly control the process parameters and operating specifications to ensure the die-cutting quality and efficiency of self-adhesive coated paper.
