Combisafe will be used for Waitrose’s own label Passata with Basil and Passata with Garlic and Onion products, moving from 680g glass jar to a 500ml carton pack.
The passatas will be filled by La Doria in Italy on food filling machines from SIG Combibloc.
John Vine, category manager, Waitrose, told BakeryandSnacks, combisafe offers a lighter long-life alternative.
“The low weight of the carton pack, due to resource-efficient use of raw materials, plus the excellent environmental performance of the unprocessed cardboard, are major factors in why the combisafe carton pack has the best environmental performance,” he said.
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. The package and product are sterilised together.
