<p>PURPOSE:To permit foods to be preserved for a long time by forming a food container body of the symthetic resins mixed with the powder of a far-infrared ray generating substance using metal die. CONSTITUTION:A food keeping container 10 consists of a container body 11 which is made by molding a mixture of the powder of a far-infrared ray generating substances and synthetic resin material using metal die. A food keeping container 13 is made by shaping into the form of a bag the synthetic resin sheet which has previously been mixed with the powder of a far-infrared ray generating substance. Since the synthetic resins are mixed with the aforesaid powder, the far-infrared rays are irradiated in such container, whereby the food inside the container can have a long shelf life. In addition, the food odor is removed and its discoloration is retarded and, in the case of dressed meat, etc., its rapid curing can be attained.</p> |
