Abstract
A receptacle () suitable for food packaging which comprises a bottom or base portion () defining a storage compartment or zone and a flange () circumferentially extending all around the receptacle contour providing an area for the closing lid to be sealed, said receptacle being made of a multi-layer thermoplastic structure comprising at least i) an upper liquid absorbent layer () that is devised to be either in direct contact with the food product to be packaged in the receptacle or separated therefrom by one or more liquid pervious layers () allowing passage of liquids from the receptacle inner surface into the absorbent layer, and ii) a non-perforated liquid and gas-barrier thermoplastic film (), and being characterized in that the surface exposed along a closed line in the circumferential flange () is of the lower non-perforated liquid and gas-barrier thermoplastic film (). 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.
