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
flange (113,123) 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 (1) 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 (5,6) allowing passage of liquids from the
receptacle inner surface into the absorbent layer, and ii) a non-perforated liquid
and gas-barrier thermoplastic film (2), and being characterized in that
the surface exposed along a closed line in the circumferential flange (113,123)
is of the lower non-perforated liquid and gas-barrier thermoplastic 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.
