A controlled atmosphere packaging system (CAPS) ostensibly was the what's-new element in the Ecolean Group booth at Cologne, Germany's Anuga FoodTec show in April, though for many West European liquid food and beverage processors, the company's entire line is new. Ecolean entered the commercial packaging market seven years ago, beginning in Russia and China and expanding westward into eastern and central Europe. Food companies in Spain, the UK and elsewhere are beginning to use the packaging system.
