For both economic and ecological reasons corrugated box manufacturers are seeking to produce acceptably strong boxes while using more recycled paper. This study was to develop hydrophilic coating agents in order to improve overall physical properties of recycled corrugated fiberboard liners. Two coating agents were developed and applied to ``S`` corrugating medium. The results showed that compression strength of new liners, named ``S-A`` and ``S-B``, were increased significantly both standard humidity and high humidity environment and it was as much as ``SK`` liner. New developed liners were also economically advantageous since new liners were estimated about one hundred fifty dollars per ton cheaper than SK liner. The study indicated that further work is needed on the coating technology and machine development.
