smart Packages - With Built-in Freshness Watchdogs

摘要

The latest packages are not only stronger but also require less material and permit efficient handling -integrated time-temperature indicators and microchips constantly indicate the product's state of quality. Active systems are even capable of improving the quality of the contents during storage. For product manufacturers, smart packaging therefore ought to be a big talking point. When it comes to "Giiggeli", their much-loved grilled chicken, the Sw^iss 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 ICneuss Gefliigel poultry company in Switzerland has therefore come up with something original for thefastidious Swiss. On the cardboard boxes of its "Bachofe-Giiggeli" 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.
