Food packaging encompasses a wide range of materials and formats, including paperboard cartons, metal cans, flexible plastic and foil pouches, rigid plastic containers, and paperboard trays. Each packaging type presents unique coding and marking challenges. Smooth, low-energy, or reflective surfaces can reduce ink adhesion and affect print clarity, while curved or irregular shapes make consistent printing more difficult. Flexible packaging may stretch or wrinkle during filling and sealing, and rigid containers often require durable, high-contrast codes to remain legible during handling and transportation.

Coding on food packaging must convey both consumer-facing information, such as production and best-before dates, and critical traceability data for batch management and regulatory compliance. High-speed, continuous production lines demand solutions that deliver reliable, fast-drying, and durable codes, even in humid or cold environments. Coding systems must also integrate seamlessly with different packaging equipment, support minimal maintenance, and maintain line efficiency while ensuring legible, consistent, and compliant markings across all types of food packaging.

①Paperboard Cartons

Paperboard cartons are widely used for cereals, snacks, and frozen foods. Their porous, often matte surfaces can affect ink adhesion, while edges and folds challenge consistent print quality. Codes must convey production and best-before dates, as well as batch and traceability information, and must remain legible throughout distribution. Coding solutions must deliver reliable, high-speed printing without compromising line efficiency.

②Metal Cans

Metal cans, used for soups, sauces, and beverages, often feature smooth, reflective surfaces that challenge ink adhesion and print clarity. Curved or cylindrical shapes require marking systems capable of precise, high-contrast coding. Codes must display both consumer-facing dates and regulatory traceability data. Reliable, fast-drying marking solutions ensure consistent performance on high-speed filling lines.

③Rigid Plastic Containers

Flexible plastic and foil pouches are common in snacks, frozen foods, and ready meals. These soft, often low-energy surfaces can stretch or wrinkle during filling, affecting code legibility. Markings must include both consumer information and traceability data, and withstand cold, humid environments. Coding solutions must provide fast-drying, durable printing for high-speed lines.

④Shrink and Stretch Wrap

Rigid plastic containers, used for dairy, sauces, and ready-to-eat meals, often have smooth, non-porous surfaces. Codes must remain legible during handling, refrigeration, and distribution. High-contrast, durable printing is essential, and coding systems must integrate seamlessly with automated filling and packing lines while maintaining continuous operation.

⑤Flexible Plastic and Foil Bags and Pouches

Paperboard trays, often used for fresh or frozen meat and produce, have porous and uneven surfaces. Ink absorption and surface texture can impact print sharpness. Codes must display production and expiry dates, batch numbers, and traceability information. Coding solutions must deliver stable, durable prints while supporting high-speed, continuous production lines.
