When it comes to customizing Plastic Security Seals, the printing method is just as important as the seal itself. Many customers ask why we recommend UV printing instead of laser marking for black plastic seals. The answer lies in the material properties of the plastic and the quality requirements of the printed information.
Different colors of plastic react differently to laser energy. Because black plastic has a high light absorption rate, laser marking may not always produce the contrast needed for clear and consistent identification. In applications where logos, serial numbers, or tracking codes must remain easy to read, print quality is critical.
For black plastic security seals, UV printing provides a superior solution by producing bright, high-contrast markings with excellent definition. This ensures that important information remains visible throughout the product's service life.
At Junyue Security Seal, we are equipped with both UV printing and laser marking systems, allowing us to select the most suitable process based on the seal color, material, and customer requirements.
