Zusammenfassung:PURPOSE:To improve slip-resistant properties by forming a resin layer with a glass transition point temperature of 0 deg.C or lower consisting of an emulsification polymer resin between unsaturated carboxylic acid or its ester and colloidal silica, on the surface of a paper fish box. CONSTITUTION:An emulsification polymer resin with a glass transition point temperature of 0 deg.C or lower is prepared by adding each specified amount of unsaturated carboxylic acid or its ester, water dispersion-type colloidal silica, an emulsifier, a polymerization initiator and ion-exchanged water and polymerizing them at a specified temperature and pressure. Next, the front and rear of a kraft paper baord 11 is impregnated with acrylic styrene emulsion and this emulsion is dried. After that, a polyethylene layer 12 is provided on the rear to obtain a kraft paper board 11 which is water-proof. Further, an emulsification polymer resin layer 10 with a glass transition point temperature of 0 deg.C or lower is formed entirely over the front of the kraft paper board of manufacture a slip-resistant paper box 20 for fish. This fish box is highly slip-resistant, and is treatable and disposable comparatively easily.
