Legal Text on Egg Cartons: Size, Placement and the Marks That Must Appear

The Carton Is a Label

An egg carton carries mandatory information directly, and the print is part of the packaging rather than a marketing addition.

Requirements vary by market but the categories are consistent: class, size, origin, date and a producer or packing code.

Missing or undersized text is the most common reason a carton is rejected at retail intake.

What Must Appear

Grade or class, egg size, number of eggs, packing date or best-before, country of origin, producer or packing centre code.

Any required method-of-production mark (for example, free range) and the associated code.

Retailer-specific requirements on top, such as a barcode and a lot code, which are not legal but are conditions of supply.

Type Size

Minimum type height is usually specified for each item, and it is measured on a capital letter, not on the whole line.

A common failure is text printed at the correct nominal size but on a textured surface where the letters thicken and fill in.

On molded pulp, add 10 to 15 percent to the minimum size to allow for ink spread, and check the result on a formed part.

Placement

The lid top is the standard position for the main information, because it is visible on the shelf and in a stack.

The end panels carry size and count, which is what a handler reads when the carton is stacked.

Keep text away from the lid edge and from the hinge, where print distorts and wears.

Legibility on Pulp

The surface is rough and absorbent, so minimum type is larger than on paperboard and contrast is lower.

A single-colour print on a natural surface gives the best legibility per cost; two colours risk registration drift on a curved lid.

Test the print at the viewing distance a shopper uses, which is about 500 mm, not at arm's length in a print room.

Change Control

Packing date, lot code and producer code change regularly, so they are usually applied by a separate print or stamp.

Ensure the stamp position does not overlap legal text. Overlap is a common and avoidable rejection.

Keep a master artwork per market with every required element listed, and check the printed carton against it before each run.

Verification

Check type height with a loupe and a scale on a formed carton, not on the artwork file.

Check every required element against the market checklist, and photograph the carton as evidence.

Review when the market or the retailer changes. A carton compliant in one market is often not compliant in the next.

Questions Buyers Ask

What must appear on an egg carton?

Grade or class, egg size, count, packing or best-before date, country of origin and producer or packing centre code, plus any method-of-production mark.

How is minimum type size measured?

On a capital letter, not the whole line. On molded pulp add 10 to 15 percent to allow for ink spread on a textured surface.

Where should the main information be printed?

On the lid top for shelf visibility, with size and count on the end panels where a handler reads them.

Why does text look wrong on the finished carton?

Because the porous surface thickens letters and reduces contrast. Always check on a formed part, not on artwork.

What is a common avoidable rejection?

A date stamp overlapping legal text. Keep the stamp position clear of the printed elements.
