SELF-ABSORBING GAS-BARRIER RECEPTACLE FOR FOOD PACKAGING AND FOOD PACKAGE OBTAINED THEREFROM

摘要

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.
