Coating was carried out on liner components of B flute, single-wall corrugated board(SK180/S120/K200) to examine the effect of liner component coatings by oxidized starch on the properties of corrugated board. Both bursting strength and edgewise compression strength(ECS) of corrugated board were improved by coating of its liner components with oxidized starch. Bursting strength of corrugated board rapidly increased with an initial increase of coating weight, but as the coating weight further increased, there was no increase in bursting strength. The results showed 30.3% improvement for $2.32g/m^2$ coating on outside liner component, 36.8% improvement for $4.84g/m^2$ coating on inside liner component and 39.9% improvement for $7.16g/m^2$ coating on both liner components in bursting strength of corrugated board. Regardless of treated liner components, ECS of corrugated board was improved by coating of oxidized starch, and especially greater improvement was accomplished when corrugated board was coated on inside liner component or both liner components at low level of coating weight - 11.3% improvement for $1.58g/m^2$ coating on Inside liner component and 11.9% improvement for $2.99g/m^2$ coating on both liner components.
