Food roll film laser marking technology uses a laser beam to accurately mark the surface of the film, achieving high-speed, non-contact information coding. This technology is suitable for marking key information such as production date, shelf life, batch, and traceability QR code. The marking content is clear, environmentally friendly, and permanently indelible, with good friction resistance and weather resistance, effectively avoiding information blurring or falling off caused by transportation and storage. Compared to traditional ink printing, laser marking does not require chemical consumables, is pollution-free and more hygienic, meets food packaging safety standards, and significantly improves product traceability and brand image.
