Smurfit Kappa Bag-in Box developed the Thermo Bag to meet the specifications of hot filling which is a commonly used processing method in the drinks industry. During hot filling, the product is pressed, filtered, pasteurized, heated and filled at a high temperature to facilitate sterilization and then immediately cooled for preservation and taste. This method has the advantage of extending shelf life, removing any harmful microorganisms, reducing costs and simplifying the process.

Hot filling is widely used in the production of fresh (not from concentrate) apple juice which has grown increasingly popular due to its freshness and health benefits. Bag-in-Box packaging is an attractive option for both consumers and producers because in addition to maintaining the product’s quality it is eco-friendly and cost-efficient.

Smurfit Kappa’s innovative new Thermo Bag is a barrier bag made from special coextruded PE film (MDPE for thermo-resistance and LLDPE for flexibility) and EVOH for oxygen barrier. “Thanks to their low carbon footprint and extended shelf life, our Bag-in-Box products offer a more sustainable choice of packaging for many industries and Smurfit Kappa relentlessly continues to develop higher performance materials for the drinks market,” said Thierry Minaud, CEO of Smurfit Kappa Bag-in-Box. “The Thermo Bag is bringing competitive advantage to producers and enhanced quality to consumers.” Smurfit Kappa’s Thermo Bag is a further example of the company’s extensive capabilities in the  drinks industry.
