Pet food packaging presents unique coding challenges due to the wide variety of packaging types, including paperboard cartons, flexible pouches, cans, and rigid plastic containers. Surfaces can vary in texture, porosity, and reflectivity, making ink adhesion and print clarity more difficult. Flexible pouches may stretch or wrinkle during filling, while metal cans and plastic containers require durable, high-contrast codes.

Codes must convey both consumer information, such as best-before dates and feeding instructions, and regulatory traceability data including batch numbers and production details. High-speed, automated production lines demand solutions that provide reliable, durable, and legible printing, even in environments with dust, humidity, or temperature variations. Coding systems must also integrate seamlessly with different packaging equipment while minimizing downtime, ensuring consistent quality and compliance across all pet food products.

①Flexible film

Flexible film is commonly used for pet wet food and snacks. Inkjet printers can print production dates, batch numbers, and QR codes clearly on the film surface, meeting traceability and anti-counterfeiting requirements. The smooth surface ensures even ink distribution and stable printing, making information clear during high-speed production.

②Plastic

Plastic packaging is widely used for pet dry food and snacks. Inkjet printers can precisely print production dates, batch numbers, barcodes, etc., on various plastic surfaces like PE, PET, etc. Due to the diversity of plastic materials, printers use different types of ink to ensure clarity in both low and high-temperature environments.

③Coated pape

Coated paper is often used for premium pet food packaging. Inkjet printers can print production dates, batch numbers, traceability codes, and other information on its surface. The coated paper surface is ideal for inkjet technology, with fast-drying ink that prevents spreading, ensuring clarity and durability of the print, meeting the needs of the premium market.

④Metal can

Metal can packaging is commonly used for wet food and perishable products in the pet food industry. Inkjet printers can precisely print batch numbers, production dates, serial numbers, etc., on the metal surface. The ink adheres firmly to the metal, ensuring the print is durable and resistant to wear. The metal surface suits high-speed production line requirements.
