Modified atmosphere packaging (MAP) increases the shelf life of fresh and refrigerated food products, the co. states. For perishable food in particular, shelf-life can have a great influence on value. The growth in markets such as healthy foods and snacks has driven the requirement for both attractive presentation and extended shelf life for products such as organic fruit, vegetables, nuts, dried fruit and cereals. The freshness of these products is largely determined by air-ventilation and the preservation of humidity within the packaging. To achieve this, a series of precise and consistent perforations are produced using a laser. Multi-chamber trays used for multi-component snacks require perforating differently, to optimize the storage life of the ingredients within that particular chamber.
