A receptacle (110, 112) suitable for food packaging which comprises a bottom or base portion (111, 121) defining a storage compartment or zone and a flan ge (113,123) circumferentially extending all around the receptacle contour providing an area for the closing lid to be sealed, said receptacle being ma de of a multi-layer thermoplastic structure comprising at least i) an upper liquid absorbent layer (1) that is devised to be either in direct contact wi th the food product to be packaged in the receptacle or separated therefrom by one or more liquid pervious layers (5,6) allowing passage of liquids from th e receptacle inner surface into the absorbent layer, and ii) a non-perforated liquid and gas-barrier thermoplastic film (2), and being characterized in th at the surface exposed along a closed line in the circumferential flange (113,123) is of the lower non-perforated liquid and gas-barrier thermoplasti c film (2). By sealing a liquid- and gas-barrier lid to the exposed surface of the liquid- and gas-barrier film of the receptacle along said closed line in the circumferential flange, it is then possible to obtain a self-absorbing, gas-barrier, package.
