interpack 2011: Smart Packages for Freshness
When it comes to “Güggeli”, their much-loved grilled chicken, the Swiss are not willing to make any compromises. Unless the chickens are reared in humane conditions, subjected to regular health checks and are absolutely fresh, they don’t make it to the table. The Ernst Kneuss Geflügel poultry company in Switzerland has therefore come up with something original for the fastidious Swiss. On the cardboard boxes of its “Bachofe-Güggeli” grilling chickens, the company prints an OnVu label, a time-temperature indicator, that accompanies the chickens on their journey to the shops. A special pigmented ink in the interior of an apple symbol is irradiated with UV light during packaging and turns blue. From then on, the color gradually fades in relation to time and temperature. The longer a “Güggeli” is stored in a warm place, the faster the color changes. When the color in the apple becomes paler than the surrounding reference color, the consumer knows that it’s better not to eat the chicken.
