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

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.
