What Ice To Clear Ink does on pack
This thermochromic ink is formulated for packaging applications where the print must change appearance at low temperature. At room temperature it shows a visible colour, then moves to near-clear once the product or pack surface cools to the set activation point, allowing text, artwork or warning marks underneath to show through.
That makes it useful for cold-chain packs, premium retail packaging and tamper aware labels, especially where staff or shoppers need a simple visual cue. The effect is direct and practical, not decorative only, and it can be combined with security artwork for added protection against copying.
- Colour to near-clear transition at a defined activation temperature
- Works on paperboard, laminated cartons and selected film structures
- Suitable for overprint or stand-alone indicator use
- Can be matched to your pack design and print process
Sizes, formats and print options
ThermoInk supplies Ice To Clear Ink in production-ready formats for packaging converters and printers. The usual starting point is trial batches, then we move into plant suitable volumes once the target temperature and print result have been signed off.
Options depend on the substrate, press setup and the level of concealment needed. In most cases we work with ink ready for flexo, screen or select coating lines, with drawdown samples used first to confirm the shift point and final appearance.
- Trial batch packs for testing on your own substrates
- Production drums or pails in agreed quantities
- Custom colour matching for the visible state
- Activation tuning for different chilled storage ranges
- Retain samples kept for repeat production checks
Where this ink suits best in South African packing lines
Ice To Clear Ink suits chilled and temperature sensitive products that move through Durban, Johannesburg, Cape Town and other inland or coastal routes. It is often requested for food and beverage packs, personal care items, pharmaceuticals, promotional packs and security labels where cold storage forms part of the use case.
Because humidity on the coast and dry winter conditions inland can affect print behaviour, we check coating compatibility and drying response before release. That matters in places like Jacobs, Prospecton, Pinetown and Port Elizabeth where converters may run different board stocks and press speeds in the same week.
- Chilled retail cartons and promotional sleeves
- Cold chain labels and indicator panels
- Security overlays for authenticity checks
- Packaging that must show a hidden graphic at low temperature
Installation on press and line requirements
This product is installed through standard printing or coating equipment, depending on the finished pack spec. No special gas supply is normally needed. Power demand stays within normal plant requirements for mixing, drying and line handling, but the substrate and drying method must be checked before you commit to a full run.
We support press startup and trial batch making so the first run does not waste material. On some lines the coating weight, drying temperature and line speed must be adjusted to keep the colour shift stable and avoid blocking, especially where the pack will be stacked soon after print.
- Standard print and coating equipment only in most cases
- No gas supply required for the ink itself
- Drying and cure settings must suit your substrate
- Line speed may need adjustment during the first run
- Trial drawdowns recommended before full production
Care, storage and servicing between runs
Thermochromic inks need sensible storage and careful handling to keep the activation point consistent. Keep containers sealed, store away from direct sun and avoid heat build-up near loading bays or steel roofs, which is a real issue during Durban summers and load-shedding recovery periods.
If a batch is left standing too long, or if equipment settings drift, the colour response can change slightly. We help with production troubleshooting, rub resistance checks, adhesion tests and threshold tuning so the pack still performs after transport, stacking and handling.
- Store in a cool, dry place away from heat sources
- Mix thoroughly before use and keep lids closed
- Check adhesion after varnish, lamination or overprint
- Run rub tests before dispatching a large order
- Keep retain samples from each batch for repeat work
What to check before you place an order
Before ordering Ice To Clear Ink, confirm the substrate, target temperature and the exact visual effect you need. If the hidden message is too faint or the trigger point is too low, the pack will not give the clarity your customer expects.
It also helps to know where the pack will be used, because refrigeration, ambient heat and municipal storage conditions can all affect the final result. If you are supplying across South Africa, tell us whether the product will move through coastal warehouses, inland depots or export packing areas so the testing is set up properly.
- Substrate type and any coatings already on the pack
- Desired activation temperature range
- Visible colour before cooling and what should show underneath
- Print method and line speed
- Whether the pack must also carry security features
