  • In this study, in order to investigate the influence of insolubilizer on the double coating structure, we carried out basic research related to the double coating formulation with four insolubilizers having various chemical types such as amino aldehyde, glyoxal and two metallic salts. It was found that although the four insolubilizers showed similar results on optical and surface properties of the coated papers, they gave different results in the printabilities of the coated papers since coating structure was significantly influenced by different reacting mechanism of the insolubilizers. Three of the insolubilizers (glyoxal, two metallic salts) showed better results than amino aldehyde type one when they were applied to top coating formulation. Metallic salts type insolubilizers showed good results in the print gloss when it was applied to top coating formulation. It was believed that amino aldehyde type insolubilizer applied top coating formulation showed good both of dry-pick and wet-pick strength.

  • This study was carried out to develop a new insolubilizer for water resistency enhancement and to evaluate its optimum apply method to corrugated paper. The addition of polyvinyl alcohol(PVA) backbone polymer to conventional starch glue caused a poor dispersibility, but flavonoid resin addition showed a good runnability and water resistency. The double coatings(top & under) of water-proof chemicals to corrugating liner made even better the water resistency of corrugating paper. This study suggested that water-proof chemical treatments be an effective method in water-resistant corrugating paper manufacturing for a cold chain system.

  • Application methods of chemicals were investigated tn minimize strength reduction of corrugated boards under the high humidity environment encountered in the cold chain system. Starch insolubilizers were introduced in the starch solution preparation of the Stain hall method and their insolubilization effect of starch binder were estimated. The performance of water repellent agents(WRA) and moisture proof agents(MPA) were evaluated in terms of water and moisture resistance. And effects of the combination of the chemicals and the coating method were also examined. Addition of the polyamine polyamide insolubilizer to the main part in the Stain hall process improved the binding force and water resistance of starch, which contributed to minimize the strength reduction of paper under the high humidity environment. AZC and Glyoxal type insolubilizers could not be used in the experiment due to an excessively increased viscosity of starch solution and the poor stability. Conventional WRA treatment to the base paper enhanced water and moisture resistance very slightly even though water repellency of the paper reached R10 by the treatment. MPA showed excellent performance than WRA not only in water and moisture resistance but in water repellency. Double coating on paper with MPA was more effective than the single coating at the same coating weight. A newly developed MPA showed excellent performance and runnability only by a single coating instead of a double coating.
