Packaging in modified atmosphere is one of the most common options to traditional food packaging technologies. In a modified atmosphere packaging system, the composition of gases inside a package is altered by replacing it with a single gas or a mixture of gases, with the aim of extending shelf life and improving presentation. Generally, MAP aims to eliminate or reduce oxygen content to inhibit bacteria and moulds. A wide variety of products can be packaged using MAP, for example, infant formula, coffee, cake mix and grated cheese. MAP equipments can be easily retrofitted to existing lines, for example, vertical form-fill-seal, horizontal form-fill-seal, capper and seamer.
