Cosmetics laser marking technology uses high-precision lasers to permanently code the packaging surface of glass, plastic, or metal materials. The marking content mainly includes key information such as restricted use date, production batch number, anti-counterfeiting traceability source code, and brand identification. Laser achieves carving, fading, or foaming effects on the surface through precise energy control, forming clear, exquisite, and tamper proof permanent imprints. This technology does not require ink consumables, eliminates chemical pollution, and meets the strict hygiene and safety standards of the cosmetics industry. Marking has strong resistance to friction, alcohol wiping, and moisture, ensuring the integrity and traceability of product information throughout the entire circulation and usage cycle. It is an important process to enhance brand image and consumer trust.
