The technology combines a print matrix – which is barely visible to the human eye but acutely sensitive to the in-pack atmosphere – with a bespoke vision system that measures the optical output of the sensor, even at the highest line speeds. The print is sandwiched behind a permeable layer in the flexible laminate.
Due for commercial launch
The system is due for commercial launch later this year by Senoptica Technologies, its chief executive Brendan Rice (pictured) told Food Manufacture.
“One estimate puts the proportion of defective modified atmosphere packs in UK fresh meat at 3% of the total.” This alone equates to some 150 million packs a year, he added.
The technology was co-developed by Advanced Materials and BioEngineering Research, and the School of Chemistry, both located at Trinity College.
