Stickers/labels are easy but add material cost and waste, can peel or get lost, and only identify the pack, not the individual egg. Direct-shell printing marks the egg itself with no consumable beyond ink.
Printing the egg gives individual traceability, survives once the carton is opened, and reads as fresher and more premium to shoppers.
Many operations use both: a label on the carton for branding and a code on the egg for traceability and freshness.
Why SHICAI: Against rubber stamps and stick-on labels, the SHICAI Six Nozzle Egg Coding Machine wins on speed, cost per egg and individual-egg traceability.
