What Body Touch Pink does on pack
Body Touch Pink is a thermochromic ink designed for packaging where a brief touch triggers a visible colour shift. In normal room conditions it holds a pink tone, then changes when a hand, warm product or other heat source is applied. That makes it useful for packs that need a quick visual cue, a sample reveal, or a consumer interaction at shelf level.
It is supplied for print applications on suitable coated and primed substrates, with the exact response tuned to the pack structure and the press conditions. The effect is best when the printed area is kept clean, evenly laid down and protected from harsh overprinting that can dull the colour change. For Durban humidity and coastal storage, this matters because moisture and poor drying can affect the finish more than the ink itself.
Sizes, supply options and how we run trials
ThermoInk supplies Body Touch Pink in production-friendly pack sizes for converters and brand owners testing a new pack line. Typical options are 1 kg samples for development, 5 kg trial pails for press approvals, and 20 kg production packs for repeat work. If a project needs a smaller starting point, we can also set up drawdown panels and trial batch making before full release.
- Sample kit for lab checks and proofing
- Trial batch for short-run promotional packaging
- Production supply for scheduled runs
- Retain samples kept on file for repeat matching
For packaging converters in Jacobs, Pinetown, Prospecton and further afield, we can align the first run with the actual substrate, coating and line speed so there are fewer surprises at press startup.
Where Body Touch Pink suits best
This ink suits promotional packs, cosmetic cartons, point-of-sale sleeves, beverage cartons, gift packaging and short-run retail campaigns that need a touch point. It is often specified where the customer must see a change at the shelf, at an activation table, or after picking up the pack. It also works well on educational or seasonal packaging where the message is linked to warmth, handling or product freshness cues.
It is not meant for every pack type. High-abrasion carrier packs, rough uncoated board, and wet or greasy surfaces can reduce the effect. If the pack needs heavy handling in transit or retail, we usually suggest rub resistance checks and coating compatibility tests before the final spec is signed off.
- Interactive promotional packaging
- Temperature cue graphics for retail packs
- Limited-edition campaigns and launches
- Consumer engagement packs with a hands-on reveal
Press setup, drying and power needs
Body Touch Pink is applied through normal packaging print processes, with the setup depending on whether the line uses flexo, screen or another compatible method. The key points are even film build, clean registration and the correct drying or curing profile. If the substrate is too cold, too damp or too tightly stacked after print, the finish can pick up marking before it fully settles.
There is no gas requirement from the product itself. Power needs depend on the existing press and drying equipment, whether that is air movement, infrared or another system already on site. For plants in Cape Town, Gqeberha and Durban, local power stability and load-shedding planning should be considered when scheduling trial runs because dwell time and stack handling can change from one shift to the next.
- Check substrate temperature before starting
- Confirm the drying or curing window on your line
- Keep the printed area free from dust and oil
- Use test strips during startup to confirm the colour shift
Care, storage and repeat-run servicing
Keep Body Touch Pink in a cool, dry store away from direct sun and heat sources. Once opened, containers should be sealed properly after use to keep the ink at spec. For plant stores in coastal areas, condensation can be a problem if the pail is moved from a cold store to a warm press room too quickly, so allow it to settle before opening.
On repeat runs, it helps to keep the retained sample, the substrate details and the press settings together. That way the next batch can be compared against the same reference. Our batch retain library supports this, and we can assist with production troubleshooting if the tone shifts, the response slows, or the ink starts to lose body on press. A small press note here saves a lot of scrap later, especially on shorter promotional jobs.
What to check before you order Body Touch Pink
Before ordering, confirm the board or film type, whether the pack will be varnished, and whether the touch effect must work after folding or overprinting. Also confirm how visible the colour change must be under retail lighting, because some displays need a stronger shift than others. If the pack will be handled by chilled goods, check the surface temperature range so the ink is not asked to perform outside its working window.
- Substrate and coating type
- Desired pink tone and change point
- Print method and drying setup
- Pack storage and transport conditions
- Need for security marking or extra verification
For converters supplying nationwide from Jacobs, the best results usually come from a short technical review first. That lets us confirm whether you need colour matching, threshold tuning, adhesion tests, UV verification setups or a trial batch before production. It keeps the job practical and cuts down on back-and-forth later on.
