A method for forming a package for creamy products comprising the following steps: - forming a tray starting from a first piece of wrapping material folding the first piece in such a way as to form a base and a continuous perimeter edge extending substantially perpendicular to the base ; - dosing a predetermined quantity of creamy product (P) inside the tray formed; - forming a lid for closing the top opening of the tray starting from a second piece of wrapping material folding the second piece in such a way as to define a covering surface and a raised perimeter edge which extends substantially perpendicular from the covering surface; - inserting the closing lid into the tray placing the covering surface in contact with the creamy product (P) positioned in the tray and the raised perimeter edge of the lid facing the perimeter edge of the tray; - sealing by sealing the lid to the tray; characterised in that the sealing step comprises the following sub-steps: - a partial sealing of the perimeter edges facing each other of the tray and of the lid in such a way as to define at least a first perimeter zone (Z1) of the edges sealed to each other and at least a second perimeter zone (Z2) of the edges not sealed and communicating with the creamy product contained in the tray; after the partial sealing steps: - a folding the facing perimeter edges of the tray and the lid on the covering surface of the lid ; and lastly - a step of pressing the creamy product (P) contained in the partly sealed tray for expelling any air present in the tray; and - a final sealing of the perimeter edges folded on the covering surface of the lid in such a way as to obtain a complete sealing of the package obtained. - forming a tray starting from a first piece of wrapping material folding the first piece in such a way as to form a base and a continuous perimeter edge extending substantially perpendicular to the base ; - dosing a predetermined quantity of creamy product (P) inside the tray formed; - forming a lid for closing the top opening of the tray starting from a second piece of wrapping material folding the second piece in such a way as to define a covering surface and a raised perimeter edge which extends substantially perpendicular from the covering surface; - inserting the closing lid into the tray placing the covering surface in contact with the creamy product (P) positioned in the tray and the raised perimeter edge of the lid facing the perimeter edge of the tray; - sealing by sealing the lid to the tray; - a partial sealing of the perimeter edges facing each other of the tray and of the lid in such a way as to define at least a first perimeter zone (Z1) of the edges sealed to each other and at least a second perimeter zone (Z2) of the edges not sealed and communicating with the creamy product contained in the tray; after the partial sealing steps: - a folding the facing perimeter edges of the tray and the lid on the covering surface of the lid ; and lastly - a step of pressing the creamy product (P) contained in the partly sealed tray for expelling any air present in the tray; and - a final sealing of the perimeter edges folded on the covering surface of the lid in such a way as to obtain a complete sealing of the package obtained. - a folding the facing perimeter edges of the tray and the lid on the covering surface of the lid ; and lastly - a step of pressing the creamy product (P) contained in the partly sealed tray for expelling any air present in the tray; and - a final sealing of the perimeter edges folded on the covering surface of the lid in such a way as to obtain a complete sealing of the package obtained. <EOS>
