There are various types of adhesive materials available
Due to the wide variety of adhesive materials, they have been widely used in different fields!
Adhesive labels, also known as self-adhesive labels, instant stickers, instant stickers, etc., are composite materials made of paper, film or special materials as fabrics, coated with adhesive on the back, and protected by silicon coated base paper. After printing, die-cutting and other processing, they become finished labels. There are various types of adhesive materials that have been widely used in different fields!
Users often inquire about the weak adhesion of adhesive labels, and the reasons for this are complex. Some customers who are not familiar with the situation may also say that the material has quality problems. In fact, the material does not have quality problems, but it is possible that the customer did not clarify the adhesion requirements or did not conduct trial pasting experiments before mass pasting. Therefore, the adhesion may not meet the ideal requirements. Based on years of experience, Zhongying Hardware has compiled the following problems:
1、 Cause analysis and countermeasures for label edge warping, label foaming, and wrinkling
1. Insufficient labeling pressure or poor contact: Check the manual labeling process or automatic labeling process to ensure a firm fit;
2. Improper selection of surface materials: Replace with thin or soft surface materials;
3. Residual chemicals or moisture on the surface of the substrate: Pay attention to the cleaning process and drying of packaging materials before labeling;
4. Labeling temperature or unsuitable temperature: Pay attention to the characteristics of the selected adhesive and avoid operating at low temperatures;
5. Improper selection of adhesive: Pay attention to the supplier's product selection recommendations and usage.
2、 Analysis and Countermeasures of Small Diameter Label Lifting or 90 ° Right Angle Arching
1. Improper selection of surface materials: Replace with thin or soft surface materials;
2. Improper selection of adhesive: For labels with a diameter of less than 3 centimeters, small packaging, and labels with a 90 degree angle design, it is recommended to consult and conduct experiments first.
3、 Reason analysis and countermeasures for label detachment/non sticking
1. Failure of labels due to improper storage conditions before use: Pay attention to the supplier's product storage and shelf life instructions;
2. The surface of the substrate is damp, rough, or contains residual chemicals: pay attention to the cleaning process and drying of packaging materials before labeling;
3. Improper selection of adhesive: Pay attention to the supplier's product selection recommendations and applications.
4、 Analysis and Countermeasures of the Reasons for Flying or Failure to Display Labels during Automatic Labeling
Peeling force too low/or too high: Select qualified matching materials according to the automatic labeling speed.
In addition, the use effect of adhesive labels is affected by the quality of materials and printing processes, so it is recommended to choose high-quality labels as much as possible.
