Toothpaste box laser marking technology uses a laser beam to perform high-speed, non-contact information coding on the surface of paper or laminated packaging. The marking content focuses on key data such as production date, shelf life, batch, and traceability QR code. Laser energy is precisely applied to the surface, forming clear and durable permanent markings through carbonization or foaming, without any chemical ink added, in compliance with the hygiene and safety standards of food and drug packaging. This mark has excellent anti friction and anti moisture properties, which can effectively resist wear and tear in transportation and storage environments, ensuring that information is clear and distinguishable from the factory to the hands of consumers, providing a solid and reliable technical guarantee for product quality tracking and anti-counterfeiting.
