摘要

A method for manufacturing an article for packaging to contain and store food products, the article of which comprises one or more chambers defined by walls, lower parts and covers where the walls, lower parts and covers have insulating means to limit the permeability of oxygen through of the article and towards one or more chambers, wherein the article for packaging is provided with integrated oxygen purification means (30) and is finished in an injection molding cycle comprising the following three process steps: - a film ( 1) Insulator with or without decoration is placed in a mold; - Material (2) plastic suitable for contact with food products is injected into the closed mold where the insulating film (1) is placed and a cavity in the plastic material (2) is achieved by cooling the outer part of the material (2) plastic when in contact with the inner surfaces of the mold and the part of the plastic material that points the direction away from the inner surfaces. The mold is partially filled at this stage; - plastic material containing an oxygen scrubber (3) is injected into the mold until the mold is filled, so that the oxygen scrubber (3) is surrounded by the plastic material (2) suitable for contact with food products .
