Packaging in a tray is a classic method of food preservation and merchandising. A tray can be sealed with a film, placed in an envelop, wrapped with a stretch film or close with a snap on lid.
In a sealed tray, the food is protected from contamination whereas its shelf life can be extended by means of Modified Atmosphere Packaging. It also promotes the product’s image and assists its consumption, especially in food categories such as ready meals, salads, dry nuts, delicatessen, etc.
