    In recent years, numerous studies have been carried out to find out the possible substitution of PE-coated paperboards used in packaging of watery of oily foods. Accordingly, this study was carried out to obtain the basic data for producing higher functional coating agents for pulp mold by evaluating various kinds of mixed coating agents. At that time, two kinds of synthetic coating agents(AKD, PVA) and three kinds of natural coating agent(CMC, corn starch, oxidized starch) were used for making the mixed coating agents respecitively. Physical properties of coated paperboards were tested. Conclusions obtained from this study were as follows.
    Based on concentrations, the proper mixture ratios were 10:99(AKD:CMC), 10:90(AKD:corn starch), 10:90(AKD:oxidized starch), 40:60(PVA:CMC), 20:80(PVA:corn starch) and 20:80(PVA:oxidized starch). The mixed coating agent of PVA:corn starch(20:80) was the most efficient coating agnet. Consequently, water and oil resistance were improved even with much addition of natural coating agents. We consider that they can be suitable for the packaging used in the storge of higher moisture vegetables and other food, and also cal be suitable for oily fried food.
