Method for Preparing a Ready-to-Eat Food Tray

A method for preparing a sterilised ready-meal package, comprising the steps of:

• providing a main container defining a main volume intended to accommodate a main food product, and having a first opening at the upper part surrounded by a first planar edge;
• providing at least one secondary container defining a secondary volume and having a second opening at the upper part surrounded by a second planar edge;
• introducing said secondary container inside the main container, so that said first edge and said second edge are flush;
• introducing at least one secondary food product inside the secondary volume;
• introducing at least one main food product inside the main volume;
• making, by means of a first sealing head facing the first edge, a perimetric seal between a covering film (4;
• 4′), arranged to cover said first and second opening, and said first edge;
• making, by means of a second sealing head facing the second edge and physically distinct from the first sealing head, an inner seal between the covering film and the second edge.
