FOOD FRESHNESS RETAINING MATERIAL CONSISTING OF NATURAL STONE INGREDIENT AND HAVING COOLING RADIATION FUNCTION OF FAR INFRARED RAY AND APPLICATION THEREOF

摘要

PURPOSE:To obtain the inexpensive subject material capable to readily producing and retaining freshness of food by exhibiting cooling radiation function of far infrared ray by fusing mixed granules consisting of natural stones of serpentine, etc., with a synthetic resin and chemical raw material. CONSTITUTION:The aimed material obtained by blending (A) 40-50wt.% mixed granules from stones consisting of serpentine, andesite and wheat rice stone and having 100-200 mesh with (B) synthetic resin such as plastics, polyethylene, foamed styrene, vinyl sheet or FRP and (C) chemical raw material and melting the blend at about 130 deg.C. The material is charged into a mold having various shapes to provide a container for retaining and storing perishable food and a plate or sheet for display.
