Plastic bottles and tubs
Dates and batch information on PET, HDPE, LDPE or PP surfaces, with polymer, colour, treatment and condensation checked.
Food packaging date and batch coding
Food and beverage coding printers for production lines
Plan readable date, lot and traceability codes around the packaging material, hygiene routine, line speed and retailer requirements.
Direct answer
What is a food and beverage coding printer?
A food and beverage coding printer applies variable information such as best-before or use-by dates, batch and lot references, production times, line identifiers and machine-readable codes to a product or pack as it moves through production.
Continuous inkjet is commonly considered for compact, high-speed codes on bottles, cans, jars, films and many primary packs. Large-character DOD is commonly considered for readable case and tray information. The correct choice depends on material, code size, speed, moisture, cleaning regime and downstream handling.
Specification principle: define the intended wording, format and verification process with your quality team. The printer should reliably execute that controlled requirement.
Application checklist
Send one real production pack.
Include the exact packaging supplier and colour, code location, line speed, print window, ambient condition and what happens after coding—chilling, pasteurisation, sleeving, packing or abrasion.
Explore date and batch codingPackaging applications
Code the primary pack and the outer case as one traceability flow.
Glass bottles and jars
Compact codes on containers or closures, considering coatings, cold-fill moisture, washing and returnable-pack processes.
Cans, lids and metal packs
High-speed variable codes on lacquered or bare surfaces, with oil, temperature, forming and abrasion included in testing.
Pouches, sleeves and film
Print position, film movement, treatment, web or pack speed and time before contact all influence quality.
Cartons and sleeves
Dates, lots and product references on coated or uncoated paperboard with colour and print location considered.
Cases and trays
Larger product, lot, logistics or machine-readable information printed directly onto corrugated outer packaging.
Production conditions
Food coding must work through the whole shift.
Assess enclosure needs, printhead position, splash risk, cleaning chemicals and safe access.
Product and ambient temperature can affect condensation, ink behaviour and drying.
Use maximum line speed and minimum product pitch, not only average production.
Stored jobs, permissions, scanners or PLC recipes can reduce manual message selection.
Position, contrast, character size and pack artwork should support fast inspection.
Define whether operators, sensors or cameras check presence, legibility or full data.
Reduce coding errors
Connect the code to the production job.
The printer can be part of a controlled sequence that selects the message, confirms readiness, detects the pack, applies the code and checks the result.

Practical answers
Frequently asked questions.
Which printer is used for expiry dates on food packaging?
Continuous inkjet is commonly used for compact date and batch codes on moving primary packs, while large-character DOD can suit bigger marks on outer cases. The surface, code size, speed and environment determine the right system.
Can a date coder print on bottles, cans and pouches?
Yes, industrial inkjet can code many bottles, cans and flexible packs. Each material and production condition should be tested because coatings, condensation, temperature and handling affect adhesion and drying.
How can the wrong date code be prevented?
Options include controlled message templates, operator permissions, barcode-scanned job selection, PLC recipe signals, prompts, line interlocks and camera verification. The required level depends on the risk assessment.
Can the same system print on the product and the case?
A coordinated control system can manage codes at more than one point, but primary-pack and case coding often use different printheads or technologies because their code size, surface and speed requirements differ.
