Chromoink Egg Shell Coding Ink(Food grade)

Chromoink Egg Shell Coding Ink is a food-grade digital barcode ink designed for direct printing on eggshells, delivering high-resolution marks that remain legible under industrial sorting and packaging conditions. This product complies with FDA 21 CFR regulations and RoHS certification, ensuring no harmful chemicals are present, and it dries rapidly to prevent smearing on high-speed production lines. Compatibility with major inkjet printer brands allows seamless integration into existing coding systems without hardware modifications.

The ink formulation uses non-toxic, food-safe pigments and solvents, meeting the strict requirements for direct contact with edible surfaces. Typical food-grade coding inks achieve adhesion strength of 4-6 N/cm² on eggshells, with a drying time of under 2 seconds at 20°C and 50% humidity. The standard viscosity range for such inks is 10-15 cP at 25°C, ensuring consistent jetting performance in continuous inkjet printers.

Primary buyers include egg grading facilities, poultry farms, and food processing plants that require traceability for quality control and regulatory compliance. The ink supports batch coding, expiry dates, and lot numbers, with typical packaging in 1L or 5L containers for bulk industrial use. Suppliers often provide material safety data sheets (MSDS) and compatibility charts for specific printer models, and buyers should confirm these details before ordering.
