Abstract

The stress and strain properties of KOCC were modified to improve the performance of KOCC as a packaging raw material. The refining consistency, refining degree, blending conditions and the grammage of handsheet were varied. The stress-strain properties, tensile energy absorption were measured. The refining improved significantly the stress and strain properties of paper, especially at lower refining consistency. The increase of grammage also contributed to the improvement in the stress and strain of paper. It was also found that the refining, blending and grammage contributed to the increase of tensile energy absorption. However, it is strongly recommended to apply the combination of refining consistency, refining degree and mechanical treatment(blending).
