Lot number printers for packaging traceability
Print lot numbers and traceability codes consistently across labels, cartons, bottles, films, bags and pouches.
Application guidance for lot code printing.
How to specify this coding application
Lot number printing helps connect each pack to production, material and quality records. The printer has to suit the amount of data required and the way products move through the line. Short lot marks may be simple, while longer traceability strings, QR codes and serialised codes require more flexible digital printing.
- Lot code, batch number and serial data printing
- Barcode and QR code options for machine-readable traceability
- Automatic incrementing and variable data control
- Print position repeatability on moving packs
- Compatibility with label, bottle, carton and film surfaces
- Operator controls to reduce manual entry errors
Recommended coding routes
Use these routes as a starting point before confirming samples, speed, substrate and integration details.
Short batch and lot marks
Hot foil can be a practical route for short repeatable codes on compatible intermittent machines.
Variable lot data
Thermal inkjet is useful when lot numbers change frequently or need barcodes, QR codes and additional product data.
Film traceability
TTO supports high-quality lot numbers and machine-readable codes on flexible films and pouches.

Lot code printing FAQs
Is a lot number the same as a batch number?
In many packaging projects the terms are used closely, but the exact data format depends on the manufacturer and traceability system.
Can a printer automatically increment lot or serial codes?
Thermal inkjet and TTO systems can support automatic serial and variable data options depending on the controller and setup.
Can lot numbers be printed with QR codes?
Yes. Digital systems can often print text and machine-readable codes together when the print area is large enough.
Which pack types can be lot coded?
Labels, cartons, bottles, flexible films, bags and pouches can all be coded when the correct printer and consumable are chosen.
