<p><P>PROBLEM TO BE SOLVED: To provide a packaging container for a powder detergent which is a powder detergent box using a moistureproof paper of a reusable wastepaper (having water dissociation properties), and has superior moistureproofness and surfactant resistance. <P>SOLUTION: The packaging container for the powder detergent is made of a paper support having a moistureproof layer, and includes a surfactant-resistant layer which is composed of oil absorptive particles and a water-soluble resin and is formed on the inner side to the moistureproof layer. The surfactant-resistant layer contains the oil absorptive particles of 10-150 pts.mass against the water-soluble resin of 100 pts.mass sold content, and the oil absorptive particles are present on the surface of the surfactant-resistant layer. The moistureproof layer is composed of a flat-structured pigment and a synthetic resin. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
