The waterproof performance of oil adhesive label paper is one of its important characteristics. In order to ensure or enhance its waterproof performance, it can be considered and implemented from the following aspects:
First, choose the right material
Choice of surface material: Choose a surface material with waterproof performance, such as PET (polyester film), PVC (polyvinyl chloride), etc. These materials themselves have excellent water resistance and can effectively prevent water penetration.
Type of glue: Oil glue itself has better waterproof performance than water-based glue. Make sure to use high-quality oil glue, and the glue layer is uniform and thick to enhance the adhesion of the label and the pasted surface, and prevent water from seeping into the edge.
Second, professional printing and processing
Water-resistant ink: During the printing process, the use of water-resistant ink can ensure that the pattern and text on the label are not easy to fade or blur in a humid environment.
Surface coating or coating treatment: The surface coating or coating treatment of the label, such as UV curable coating, waterproof polish, etc., can further enhance its waterproof performance. These coatings form a protective film that effectively blocks moisture and stains.
Third, strict quality control
Raw material screening: strict screening and testing of raw materials to ensure that they meet the requirements of waterproof label paper. Choose materials that have been specially treated or have a higher waterproof rating.
Production process monitoring: Strict monitoring and testing of the printing and processing process to ensure that each link meets the quality standards. In particular, pay attention to the coating uniformity and dryness of the glue to avoid the deterioration of the waterproof performance of the label caused by the glue not drying out.
4. Field test and evaluation
Environmental simulation test: After the production of waterproof oil adhesive label paper, field tests are conducted to evaluate its waterproof performance. You can simulate different humid environments (such as high humidity, water, etc.) to observe the change of the label.
Performance evaluation: The waterproof performance of the label is evaluated according to the test results, and adjusted and optimized as needed. For example, if it is found that the waterproof performance of the label is not good in a specific environment, you can consider replacing the material or improving the processing process.
5. Precautions
Storage conditions: When storing waterproof oil-adhesive labels, keep the environment dry and well-ventilated to prevent the labels from being exposed to moisture for a long time.
Application environment: When using waterproof oil adhesive labels, ensure that the surface is clean, dry, and free of impurities such as oil and dust. These impurities may affect the label's adhesion and water resistance.
In summary, through the selection of appropriate materials, professional printing and processing, strict quality control and field testing and evaluation measures, you can effectively enhance the waterproof performance of oil adhesive label paper. The implementation of these measures will help improve the reliability and durability of labels, and meet the demand for high-quality marking materials in the industrial manufacturing field.
