Abstract: This invention relates to a conditioning method for perishable products (2) with a preservation temperature, using a heat sealable packaging (1) with two transverse edges (11, 12) and two longitudinal edges (9). According to this invention, it comprises the following steps: make a heat sealable packaging comprising a central compartment (5) bonded with at least one lateral compartment (6), the compartments (5, 6) being sealed on three of their sides, place a means (8) in each lateral compartment (6) for keeping the perishable product (2) at its preservation temperature, put the perishable product (2) inside the central compartment (5), and seal the fourth side of the compartments (5, 6) so as to simultaneously close the compartments (5, 6) so as to form a sealed packaging with a central compartment (5) or leak tight with respect to each lateral compartment.

Abstract: The packaging for food products of the invention is intended to comprise two superimposed composite sheets (4, 5), each composite sheet comprising at least one layer made of a heat-sealable plastic material (14) forming the inner surface of the packaging.
