Bosch said the unique opening machanism in its Pull Pack is designed for manufacturers in the booming convenience food market. The design is suitable for products traditionally packaged using flow-wrapping technology, said Friedbert Klefenz, president of Bosch Packaging Technology. He was demonstrating the design at Bosch's launch of the product at the Total Packaging and Process Exhibition in Birmingham this week. To open, the product is held in one hand by the consumer, who then tugs on the seal fin at the other, shorter end. This pulls off the sleeve, revealing the top end of the product. The other end remains in the rest of the package. Since the product does not have to be touched, hygiene is maintained, Klefenz said. "The controlled opening of the pack, and the clearly defined pull-off section of the packaging opens up a raft of possiblities for marketing," Bosch said in a press release. The company suggests that the pull-off section could be used as a collectable token for promotions and competitions. The Pull Pack is not an entirely new style of packaging. The opening mechanism is a development of an existing, widely-used packaging method, thus manufacturers do not need a new process to make the switch. They do need to buy an additional module from Sigpack Systems to add to their existing flow-wrapping machines. Klefenz told FoodProductionDaily.com that the package was being tested by a number of manufacturers in some markets. He said the company initially was targeting the chocolate and cereal bar sector.
