A new Insolubilizer Development to Enhance the Water Resistency of Corrugated Paper and its Apply Methods Evaluation

골판지의 내수성 향상을 위한 내수화제 개발과 적용방법 평가

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.
