Abstract: Packaging suitable for food products has at least one wall which is formed in a semi-rigid material such as cardboard and has at least one edge defining an opening for inserting articles, in particular foods, and at least one first flap articulated to that edge along a folding line. The packaging can be conformed into a service configuration in which the flap uncovers the opening and a first storage configuration in which the flap closes the opening. The wall includes reversible deformation arrangements for conforming the packaging into a second storage configuration in which the first flap clamps the wall in a substantially sealed manner along the folding line and in the area of the edge.
