    摘要: A far infrared ray radiating transparent resin composition is disclosed. The composition is composed of a transparent resin and a far infrared ray radiating ceramic material. The ceramic material which is added to the resin in the amount of 1-30 weight parts, has an SiO.sub.2 purity of over 96.0%, and an average particle diameter of 0.1-15 .mu.m. The resin composition according to the present invention not only radiates far infrared rays, but also maintains transparency at an acceptable level. Therefore it can be applied to various products where the both transparency and extended freshness of food are required.
