保冷材及び保冷材の製造方法

Cold-keeping material and method for producing the same

Abstract

<P>PROBLEM TO BE SOLVED: To provide a cold-keeping material and a method for producing the same, wherein the cold-keeping material can be formed into the one with small total weight by using a water-soluble polymer resin as a raw material in an amount as small as possible, and long time temperature keeping can be achieved to products to be kept cold. <P>SOLUTION: A cold-keeping body 2 is obtained by kneading reverse osmosis membrane water, which is produced from common water such as tap water by a reverse osmosis membrane method, and a gelling agent mainly composed of the water-soluble polymer resin. The cold-keeping body 2 is held in a package 1 formed from a film such as plastics and hermetically packaged. <P>COPYRIGHT: (C)2005,JPO&NCIPI
【課題】できるだけ少量の原料となる水溶性高分子樹脂を用いて、保冷材の全体重量を軽量に成形することができ、しかも、被保冷物に対して長時間の温度保持を図ることができる保冷材及び保冷材の製造方法を提供する。 【解決手段】水道水等の一般水を逆浸透膜法により逆浸透膜水を生成して、この逆浸透膜水と、水溶性高分子樹脂を主成分としたゲル化剤とを混練して保冷体2を得て、この保冷体2をプラスチック等のフィルムにより製袋した包装体1内に収容して密封包装させる。 【選択図】 図1
