In FIGS. 1A and 1B, a gas adsorbent 2 and a superabsorbent polymer material 3 are fixed between two layers of base materials 1 and 1', and a sheet material for shaping 4 is layered on one base material 1'. The base material sheet 5 is formed by applying the same. The food packaging container A is thermoformed into a tray shape or a box shape so that the shaping sheet material 4 of the base sheet 5 constitutes an outer wall. As the thermoforming means, commonly used molding means are used. For example, by a method such as hot pressing or vacuum forming.

になると保温、保冷効果が失われる。 As the base materials 1, 1', nonwoven fabric or synthetic paper mainly composed of synthetic fibers is used. Since the nonwoven fabric and the synthetic paper need to be thermoformed in a subsequent process, they must both be molded from thermoplastic resin. For example, polypropylene, polyethylene, fibrous polypropylene coated with vinyl acetate, and the like are preferably used as materials. In addition, both nonwoven fabric and synthetic paper are porous, and their basis weight is 30 to 100 g/m 2
is preferred. If the basis weight is less than 30 g/m 2 , there will be problems with strength and shape retention, and if it is more than 100 g/m 2 , the heat-retaining and cold-retaining effects will be lost.

These mixtures are fixed and held between the base materials 1 and 1'.As a means of holding the mixture, it is possible to physically fix it by simply passing it between embossing rolls, but it is possible to fix the mixture firmly between the base materials 1 and 1'. When this is done, a vinyl acetate or acrylic adhesive (emulsion type) may be applied by spraying or gravure at a rate of 5 to 20 g/m 2 .
Furthermore, the above-mentioned fixing can also be carried out by partially compressing the base materials 1, 1' as shown in FIG. 3 and heat-sealing them. The total amount of the mixture of gas adsorbent 2 and superabsorbent polymer material 3 is 30 to 100 g/
It is preferable to keep it at around m 2 in order to maintain freshness.
