Study on the Compresion Strength Improvement from Process Diagnosis of Corrugated Cardboard Packaging
In this paper, with the diagnosis of progress, we studied the effect of adhesive amounts and warp conditions for improvement of the compression strength in corrugated packaging case. The result of the study on compression strength according to functional speed and adhesive amounts by adjustment of applicator roll and doctor roll gap in gluer shown the effect that compression strength increased about 2.2% and adhesive strength increased about 1.6% when gap was adjusted to 0.2 which is used to 0.17 in production of double wall corrugated fiberboard container. And study in compression strength by the conditions of warp in corrugated fiberboard shown that downer warp condition was higher than upper warp condition. In the linearboards, it is possible assuming that lower basis weight corrugated midium(S base sheet) is weaker in compression strength by warp but this is because of the difference of shape condition between wire-side and felt-side.
