TAILIEUCHUNG - RETORT FLEXIBLE PACKAGING:The Revolution Has Begun

Already big in Asia and Europe, retort flexible packaging is poised to penetrate deep into lucrative North American markets still dominated by metal cans and glass bottles. by Andrew Mykytiuk, Editor-in-Chief Strength of the pouch has always been an issue. Most people associate metal cans with strength and can’t believe plastic can be as strong as steel—even people in the packaging industry. “I had one client take a #10 pouch and It tastes better throw it across the factory floor to see if Food packaged in a conventional can the seal would hold,” says Hoss. “Another must be cooked approximately twice. | RETORT FLEXIBLE PACKAGING The Revolution Has Begun Already big in Asia and Europe retort flexible packaging is poised to penetrate deep into lucrative North American markets still dominated by metal cans and glass bottles. by Andrew Mykytiuk Editor-in-Chief Cover art courtesy of Rohm and Haas FLEXIBLE PACKAGING OCTOBER 2002 19 COVERSTORY Retort systems use steam or superheated water to cook food in its own package extending shelf life and ensuring food safety. Retort flexible packaging is not new. In fact it has been around since the late 1960s when the US Army began looking to replace its unpopular canned C-rations. That project led directly to Meal Ready to Eat MRE packaging which the Army uses to this day. Since then retort packaging has evolved from a mostly aluminum foil structure to a sophisticated multilayer high barrier laminate package. The military like most entrenched bureaucracies is resistant to change. But there was virtually no resistance to the rapid adoption of the MRE. Why Because food packaged in the retort pouch tastes much better than canned rations. It tastes better Food packaged in a conventional can must be cooked approximately twice as long as food contained in a retort pouch. To sterilize the food contained in either form of packaging it must be brought up to approximately 245 F and kept there for a specified period of time. Retort packages have a thin profile and a high ratio of surface area to volume says Dr. Rani Stern chief technical officer CLP Packaging Solutions. Heat penetrates the food much more quickly when it only has to reach the inside of a half-inch-thick mass rather than a much larger mass in a round can. Dean Hoss president of flexible packaging converter Pyramid Group says the product nearer the can wall is overcooked. Retort time is reduced 30 to 50 and by as much as 57 in a flexible pouch. You don t overcook and soften the food into mush. If it s packaged in retort flexible packaging no matter what it is it tastes better
