The goal was to create a new ketchup container that could withstand a hot fill process that would be a cost-effective alternative to aseptic filling.
Big names in the industry like Heinz have packed their ketchup in PET with oxygen scavengers filling the containers aseptically. The aseptic process is notoriously expensive due to the strict CIP (Clear in Place) procedures because the growth of microorganisms at room temperature is very high and the risk of contamination is also high. The bottling line must be free of dead spots and must be made of stainless steel (eg AISI 316) and the surface must be smooth. All these precautions greatly increase the cost of the plant and its maintenance compared to the almost standard hot fill process.
