Complete Traceable Egg Marking Solutions: From Individual Eggs to Outer Cartons
To build a fully traceable chain, we offer integrated coding and marking solutions across three levels:
-
Individual eggs (laser or inkjet direct marking)
-
Trays / inner packs (direct printing or label application)
-
Outer cartons / shipping cases (case coding for traceability association)
Below we break down the best-suited technologies for each stage.
Part 1: Individual Egg Coding – A Unique ID for Every Egg
On high-speed egg processing lines, we provide two proven, production-ready approaches:
Option A: Laser Marking System (Non-Contact, No Consumables)
-
Key benefits: Zero ink, zero solvents, zero consumable costs. Plug-and-play operation with no chemical contamination risk. Marks are permanent, smudge-proof, and abrasion-resistant.
-
Installation: Comes with an adjustable floor stand for easy integration above existing conveyors. Capable of on-the-fly marking without stopping the production line, provided conveyor motion is stable.
-
Best for: Producers prioritizing low long-term operating costs, environmental sustainability, and ultra-durable marks.
Option B: Thermal Inkjet Printers (Multiplex or Single-Head)
| 6-Head Egg Inkjet Printer Includes its own conveyor system and adapts to various site conditions. Supports rich content (logos, Chinese/English characters, numbers, simple graphics) with fine print quality. Six heads work simultaneously for exceptionally high throughput.
| Single-Head Egg Inkjet Printer Ideal for small-to-medium production volumes or R&D/lab use. Compact footprint, flexible placement, and delivers the same print quality as the multi-head version. Easy to maintain and operate.
|
Field-Proven: All above solutions are already operating reliably in major egg producers' factories and have passed rigorous production validation.
Part 2: Packaging-Level Coding – From Trays to Full Cases
To enable complete traceability, coding must extend beyond individual eggs. We support two approaches: printing directly onto packaging materials or printing onto applied labels.
2.1 Label-Based Coding
-
Suitable for pre-printed brand labels. We can supply label applicators or LPA (Label Print & Apply) units for fast, accurate label placement.
2.2 Direct Printing on Trays, Boxes, or Cartons
We offer both laser and inkjet solutions. The table below highlights their key differences:
| Feature | Laser Marking | Thermal Inkjet Printer (TIJ) | Piezoelectric Inkjet UV Printer(PIJ) |
|---|---|---|---|
| Consumables | None – no ink, no solvent | Requires ink/fluid; | UV inks, offering excellent adhesion |
| Marking Area | Wide range – from 70×70mm up to 300×300mm, with larger custom sizes available | Print heights: 12.7/25.4mm (can be stitched with multiple heads for expanded width) | Print heights: 54/72mm (can be stitched with multiple heads for expanded width) |
| Material Suitability | Laser type (CO₂, fiber, etc.) is selected based on packaging material after free sample testing | Uses cartridges with alcohol-soluble inks – ideal for porous materials like cardboard, uncoated labels, kraft paper. | UV Ink cures instantly under UV lamp – excellent adhesion on both porous and non-porous surfaces (plastics, coated boards); marks resist common solvents |

2.3 Alternative: Continuous Inkjet (CIJ)
-
For customers who only require simple date/batch codes without barcodes, QR codes, or high-resolution graphics, our Continuous Inkjet (CIJ / small character) printers offer a dependable and cost-effective alternative.
