As an important part of modern packaging, logistics and commodity identification, the dimensional stability and shape accuracy of Self-adhesive labels are directly related to the application effect and user experience of labels. In the production process, how to ensure that the size and shape of Self-adhesive labels meet the design requirements is an important issue that manufacturers need to face.
First of all, starting from the selection of raw materials, the quality of the substrate of Self-adhesive labels must be strictly controlled. The uniformity and stability of the substrate are the basis for the stability of the label size. Therefore, before production, the substrate should be strictly tested for quality to ensure that its thickness, strength, flatness and other indicators meet the standards. At the same time, it is also crucial to choose an adhesive suitable for the label application scenario, because the viscosity, curing speed and weather resistance of the adhesive will affect the label's pasting effect and dimensional stability.
In the printing and processing stages, precise control of various process parameters is the key to ensuring the accuracy of label size and shape. During the printing process, it is necessary to ensure the uniform distribution and rapid drying of the ink to avoid changes in the label size due to the flow or shrinkage of the ink. In addition, the accuracy and stability of the printing press also directly affect the printing quality and dimensional accuracy of the label. Therefore, regular calibration and maintenance of the printing press to ensure that it is in the best working condition is an important measure to control the dimensional stability of the label.
In the die-cutting and waste discharge process, the process parameters also need to be strictly controlled. The accuracy and durability of the die-cutting tool are crucial to the shape accuracy of the label. Therefore, when selecting the die-cutting tool, factors such as its material, hardness and edge accuracy should be considered to ensure that the tool can meet the die-cutting requirements of the label. At the same time, the control of die-cutting pressure and speed also directly affects the shape accuracy and edge quality of the label. In the waste discharge process, it is necessary to ensure that the waste is completely separated from the label to avoid the influence of waste residue on the size and shape of the label.
In addition, the ambient temperature and humidity are also important factors affecting the dimensional stability of the label. During the production and storage process, a relatively stable ambient temperature and humidity should be maintained to avoid dimensional changes of the label due to environmental changes. At the same time, regular sampling of finished labels and the use of precision measuring tools to detect their size and shape accuracy can timely discover and correct problems in the production process.
In summary, controlling the dimensional stability and shape accuracy of Self-adhesive labels requires starting from multiple aspects such as raw material selection, printing processing, die-cutting waste removal, and environmental temperature and humidity control. Through strict quality control, precise process parameter settings, and regular testing and calibration, it can ensure that Self-adhesive labels maintain stable size and shape accuracy during the production process, thereby meeting the needs of various application scenarios.
