Essential information on food packaging, such as expiration dates, batch numbers, barcodes, and manufacturing details is crucial for ensuring product traceability, quality control, and regulatory compliance. Various technologies, including inkjet printing, laser marking, and thermal transfer printing, are used to apply these codes on different packaging materials like plastic, glass, metal, and cardboard. Accurate and legible coding informs consumers, facilitates recalls, and assures product safety and authenticity. As the food industry evolves, innovations in package coding continue to improve efficiency, durability, and sustainability.
