The premium food retailer will now use SIG Combibloc’s flexible filling technology and the retortable combisafe carton pack for its own-label Passata with Basil and Passata with Garlic and Onion products, moving from 680-g glass jar to a 500-mL combisafe carton pack.

The passatas will be filled by La Doria in Italy on food filling machines from SIG Combibloc. Through the use of three modular filling units a hugely diverse range of products can be filled in combisafe – the size and quantity of the chunky product ingredients can vary in virtually any respect and can be measured out precisely. After the products have been filled into the carton pack, which is open at the top, the carton top is sealed ultrasonically. The carton packs are then automatically conveyed into an autoclave. Package and product are sterilized together. In the area of carton packs for long-life food, the use of a rotary autoclave is said to be a world first, delivering optimum temperature distribution inside the carton pack.
