CIJ Coding for Packaged Foods | High-Quality Marking Solutions

Packaged food lines operate at high speed and under constant demand. From flow-wrapped snacks to frozen entrées, each product type introduces new variables such as curved surfaces, condensation, and tight label space. Meeting those challenges calls for packaged food coding solutions designed for industrial food packaging.

KEYENCE CIJ systems deliver consistent print performance without slowing production. Non-contact printing adapts to film, plastic, cartons, and glass with precision. Automatic ink conditioning and stable droplet control keep codes sharp through long shifts. The result is a readable mark that withstands handling, transport, and temperature changes common in packaged foods.

Accurate coding is part of food safety and consumer confidence. Every printed lot code and expiration mark links production data to traceability records. Missing or unclear information can cause recalls, compliance issues, and wasted product. Reliable date coding for packaged foods helps identify when and where an item was made, supports inventory rotation, and protects brand reputation.

Regulatory expectations across the food industry continue to grow. Clear, durable print supports packaging compliance coding for distributors, retailers, and auditors. High-quality marking also communicates transparency to customers. A crisp, easy-to-read code signals accountability and professionalism in every package.

Food packaging comes in nearly every shape and material. Pouches, trays, sleeves, and coated cartons each present a different surface and workflow condition. CIJ technology handles these variations with steady output at production speed. Printing lot codes on food packaging often means dealing with moisture, curved surfaces, and limited clearance. The fine droplet stream of a CIJ printer can mark those surfaces without contact, avoiding smears or transfer.

In industrial food packaging, flexibility is key. CIJ systems maintain adhesion on both porous and non-porous materials while using fast-dry inks that stay readable in cold or humid environments. Each mark carries production data such as best-before dates, batch numbers, or serialized lot codes tied directly to traceability systems. Consistent coding across packaging types keeps visibility strong from processing to shipment.

KEYENCE CIJs stand out for their fast and accurate coding capabilities. They enable manufacturers to identify and trace defective or substandard products. This feature is crucial in the packaged food industry as it ensures that only high-quality products reach consumers.

CIJ technology minimizes the chances of human error in packaged food coding and marking processes. This leads to more reliable and efficient coding, ensuring that all packaged food products are accurately labeled with the correct information.

KEYENCE developed its MK-G Series CIJ printer for food packaging to meet the demands of high-volume production, featuring automatic cleaning, smart startup and shutdown routines, and a stainless-steel housing rated IP55 for damp or washdown environments. These systems reduce maintenance and downtime, letting operators focus on production.

Stable ink circulation and precise viscosity control support long runs while maintaining drop accuracy, while fast-dry and MEK-free inks provide strong contrast on flexible film, PET, and coated cartons. A compact printhead simplifies integration beside conveyors or fillers, while internal diagnostics and event recording help supervisors track line performance.

Continuous inkjet printers feature non-contact operation, which prevents damage to packaging while supporting high throughput. Automated ink management minimizes waste, and durable components limit downtime between runs. Operators gain simple control through an intuitive interface that shortens setup time during product changeovers.

In packaged food coding solutions, this reliability supports consistent coding, dependable compliance, and long-term cost control. CIJ technology adapts as packaging designs change, giving producers confidence that each printed code will remain traceable and legible when products reach store shelves.
