UV curing adhesives are widely used in the packaging industry, but some common problems may arise during their application. This article introduces common issues with UV curing adhesives and their solutions, helping users better address these challenges.
UV sealing glue, as a highly efficient sealing material, is commonly used in the packaging industry. However, some common problems may arise during use, affecting the quality and effectiveness of the seal. The following are some common problems and solutions encountered by users.
1. Problem: The seal is not strong and is easily damaged.
Solution: This may be due to the UV sealing glue not being fully cured. Increase the curing time to ensure the seal is completely dry.
2. Problem: Bubbles or dents appear at the seal.
Solution: Bubbles or dents are usually caused by air not being completely expelled during the sealing process. It is recommended to use a lower sealing speed and to squeeze out as much air as possible from the packaging bag before sealing.
3. Problem: Expired UV sealing glue leads to poor results.
Solution: Regularly check the production date of the UV sealing glue to avoid using expired products. If the product is expired, replace it with new sealing glue to ensure the sealing effect.
4. Problem: Uneven sealing, with wrinkles or other defects.
Solution: This may be due to uneven light source or excessive sealing time. Try to maintain even light irradiation and control the sealing time to avoid excessive heat causing deformation.
By understanding common problems and solutions for UV sealing glue, users can better address challenges encountered during use, improve sealing efficiency and quality, and ensure the integrity and safety of product packaging.
