Positive ID labelling has developed a new multi-purpose label that can both carry printed data and indicate when pre-packed foods have achieved the correct temperature. The label is printed with a special ink strip that remains invisible until it changes to black at the specified temperature, ensuring the food has been properly heated. The change is permanent and irreversible.
The rest of the label can be used to show essential information, such as batch number, date and other variable data, which is printed and applied with a simple one or two-line hand-held labeller. The special ink has been developed in the US, where it is already widely used in food processing.
The whole label - material, adhesive, standard and temperature-sensitive inks - is specified, so that it remains secure and legible after the food has been heated.
Positive ID Labelling makes its own labels and supplies a choice of hand-held labelling machines. All systems are supplied with full technical back-up and on-site support.
