Reliable coding for pet food packaging
Pet food packaging needs more than a visible date code. Batch numbers, best-before dates, production data and 2D codes must remain clear throughout filling, handling, storage and distribution.
Macsa ID helps pet food manufacturers select the right coding and marking solution for each packaging format. From dry food bags and treat packs to wet food pouches, cans, trays, cases and pallets, we assess the real pack, the coding area, the line speed and the required message before defining the most suitable technology.
Coding across every pet food packaging format
Pet food is packed in a wide range of materials and formats, each with different coding requirements.
Dry food bags, sacks and flexible treat packs may require clear variable codes on printed, glossy or multilayer films. Wet food pouches, trays and cans can involve limited coding areas, curved surfaces, moisture or demanding downstream processes. Secondary packaging also needs reliable identification for case packing, warehouse management and distribution.
Macsa ID solutions can apply:
- Best-before, expiry and production dates.
- Batch, lot and shift data.
- Product references and variable text.
- Barcodes, QR codes and DataMatrix codes.
- Traceability, logistics and promotional data.
- Case and pallet identification labels.
The right technology for the real pack
There is no single coding technology that suits every pet food application. The correct choice depends on the packaging material, coating, coding window, line speed, operating conditions and expected code quality.
TTO for flexible packaging
Thermal transfer overprinting remains an effective option for flexible films, bags, pouches and treat packs where ribbon-based coding is the right fit. It can apply variable text, dates, batch codes, barcodes and 2D codes with high print quality.
iLumiFlex for compatible films
For compatible flexible packaging, iLumiFlex offers a UV laser alternative to TTO. It creates permanent, high-contrast codes directly on the marking layer of the film, without ribbons, ink or thermal printheads.
This can help reduce the interventions associated with ribbon changes while maintaining clear coding for dates, batch information and traceability data. Film composition, inks, coatings and barrier layers must always be validated on the final pack.
Laser coding for selected materials
CO₂, fibre and UV laser technologies can be assessed for compatible cartons, printed surfaces, films, cans and rigid packaging. Direct laser coding can create permanent marks without ink or ribbon at the point of coding.
The laser source and configuration must be matched to the material, surface finish, required contrast and production speed.
CIJ and TIJ for flexible production needs
Continuous inkjet is a versatile option for curved, irregular or difficult-to-mark surfaces at production speed. Thermal inkjet can provide high-resolution text and 2D codes on selected packs, labels and outer cases.
Designed for real production conditions
Pet food production environments can involve airborne dust from dry food, moisture around wet food lines, printed or reflective films, limited coding areas and frequent product changes.
Reliable coding depends on more than the printer or laser source. The final result must consider:
- Code contrast against the packaging design.
- A stable and accessible coding position.
- The available message space.
- Production speed and repeatability.
- Packaging handling after coding.
- Resistance through distribution and storage.
- Accurate management of variable data.
By validating these factors before installation, manufacturers can select a coding process that works consistently across the full production cycle.
Traceability and code verification
Clear codes need accurate data behind them. When manufacturers handle multiple product references, flavours, pack sizes and markets, controlling dates, batches and variable information becomes essential.
Macsa ID coding systems can be connected with production data to reduce manual entry and support more reliable message management. Where required, vision systems can check code presence, position and legibility before incorrectly coded packs move further along the line.
This creates a stronger link between coding, quality control and traceability from the primary pack to the final pallet.
Lower-consumable coding where the application allows
Laser coding can reduce the need for inks, ribbons and solvents when the packaging material is compatible with the selected laser source. For flexible packaging, iLumiFlex provides a route to direct UV laser coding on suitable films.
The objective is not to replace every existing technology. It is to identify where a direct coding process can improve code permanence, reduce routine interventions and support a more efficient production line.
Validate the code on your final packaging
Every coding project should start with the real packaging sample: the final material, print design, coating, coding area and required message.
Testing the application helps assess:
- Code contrast and readability.
- Coding position and available space.
- Performance at the required line speed.
- The visual appearance of the pack.
- Resistance to handling and distribution.
- Compatibility with films, seals, barriers and coatings.
