The food field is perhaps where the use of trays is most evident.
Very important is the traceability of the food contained in the trays and it is an obligation that involves all operators in the food sector who must indicate on the packages and containers the dates of preparation, expiry date and the description of the contents. All this information is reported on the labels with the purpose of conveying promotional nutritional messages, protecting quality and freshness, protecting against attempts to open the product.
Food trays can carry labels of different types, such as: primary decoration labels, multilayer labels, “open and close save freshness”, “anti-breakage seals”, “multipack”.
