to serve pret&rsquos new &lsquomac n cheese&rsquo flavours &ndash &lsquomacaroni cheese prosciutto&rsquo and &lsquomacaroni cheese kale & cauli&rsquo &ndash the manufacturer of disposable packaging solutions has developed the mac n cheese hot food box.cooked within the packaging and then held on the hot shelves, the mac n cheese hot food box transfers sufficient heat into the food to allow the product to cook well without becoming overcooked.the box has been designed with a separate base and lid &ndash rather than as an integrated pack &ndash so protects the macaroni cheese whilst allowing the consumer to eat easily from the box base when required.the lightweight pillopack design has special greaseproof papers on both sides, to provide a grease barrier on the inside and also on the outside to prevent greasy finger marks.
