A bright yellow made for flexo packaging lines
Waterbased Flexo Yellow is formulated for printed packaging where colour strength has to hold up on press and still look clean on shelf. It is used on cartons, coated paper, paper labels and selected absorbent packaging substrates, with the aim of giving a strong yellow shade that transfers well through typical flexographic print conditions.
For Durban and other coastal plants, the waterbased format helps with day to day handling in warmer conditions. It is suited to converters that need dependable ink flow, consistent shade control and a practical option for packaging runs that change from one SKU to another. The finish is designed for clear, bright yellow output rather than dull, muddy tones.
- Bright yellow colour for packaging print work
- Waterbased system for flexo applications
- Suitable for short runs and repeat production
- Works well where clean press transfer is needed
Where this yellow works best on packaging
This product suits food and non-food packaging where yellow is used for branding, warnings, flavour cues or product identification. It is commonly checked on folding cartons, sleeves, inserts, paper-based packs and other packaging where the print surface can take a waterbased ink without excessive soak-in.
In humid areas such as Jacobs, Prospecton and parts of Cape Town, substrate condition matters. If the board has been stored near open docks or in a loading bay during load-shedding, moisture can shift and affect laydown. That is why we recommend testing the exact board, film or coated stock before full production. A good fit on one pack type does not always mean a good fit on another.

- Paper labels and sleeves
- Promotional packaging inserts
- Absorbent paper-based packs
Sizes, supply options and batch control
Waterbased Flexo Yellow is supplied for packaging converters in sizes that suit both trial work and regular production. Typical supply options include 1 kg sample packs, 5 kg pails and 20 kg drums, with batch identification for repeat ordering and retain matching. Where needed, we can help with drawdown panels and trial batch making before a full run goes ahead.
For plants running multiple jobs, batch retain records are useful when a customer wants the same yellow again a month later. Keeping the same target shade, press setting and substrate reference reduces surprises on re-order. If a conversion line is spreading jobs across Durban South, Pinetown, Johannesburg or Pretoria, having the correct batch notes on hand saves time on the next setup.
- 1 kg, 5 kg and 20 kg supply options
- Batch retain library support
- Trial batch and drawdown testing available
- Useful for repeat packaging runs
Press setup, drying and power needs
This ink is meant for standard flexo press use and does not need special gas equipment. Normal drying on press should be matched to the line speed, substrate and ambient conditions. Many packaging lines rely on heated air or controlled drying sections rather than any gas-fed process, so the practical checks are around airflow, drying balance and press stability, not extra site installations.
Power needs sit with the press and dryer setup already in place at the converter. On sites affected by load-shedding, operators should confirm that the press restart sequence, dryers and circulation systems come back cleanly after a power interruption. If the ink film starts to build up or dry too slowly, check the first reels or sheets before running a full batch.
- No special gas installation required
- Works with standard flexo drying systems
- Check restart performance after outages
- Match drying to substrate and line speed
Care, servicing and production support
Like most waterbased packaging inks, this product performs best when containers are kept closed, stored out of direct sun and protected from extreme temperature swings. In coastal storage areas, keep lids sealed to reduce skinning and contamination. If a pail has been open during a hot shift, stir before use and check whether the viscosity still sits in the expected range.
ThermoInk supports converters with adhesion tests, rub resistance checks, UV verification setups, coating compatibility and production troubleshooting. Where the job is sensitive, we can also help with threshold tuning and press startup support. A neat pressroom routine, clean anilox handling and proper cleaning after each run all help keep the yellow shade steady.
- Keep containers sealed between uses
- Stir before application if stored open
- Check viscosity after hot or humid storage
- Use cleaning routines that suit waterbased ink
What to confirm before placing an order
Before ordering Waterbased Flexo Yellow, confirm the substrate, print side, target shade and the line speed you are running. It also helps to know whether the pack will face heat, rub contact, stacking pressure or any secondary coating. If the packaging needs a visual cue, check the exact yellow tone against the final artwork and not only against a swatch on paper.
Please also share the production location, expected delivery town and any storage limits on site. Our teams in Jacobs, Durban South, Pinetown, Prospecton, Cape Town, Gqeberha, Johannesburg and Pretoria can then match supply to the job and avoid delays. For security printing requirements or special pattern work, Pieter van Wyk and the production team can advise on the best setup. Small details matter here, because a pack that looks fine on the bench may still fail when it goes through a wet line or a tight stacking schedule.
