종이구조 및 무기충전제가 종이의 단열특성에 미치는 영향

Abstract

The packaging with environment-friendly materials become more important issue since the concern forthe environment and the disposal of waste such as the packaging materials has increased. Although thepaper based packaging such as corrugated box are widely used as a typical environment-friendly packagingstuff, the heat insulation properties of paper packaging did not get many attention. In this study,the heat insulation properties of paper were deeply evaluated to improve the functional properties aspackaging material of the cold storage goods. The simple device for evaluating the heat insulation of paperproduct was developed. Subsequently, the changes in the heat insulation depending on the paperstructure and the addition of the inorganic fillers were investigated by using the instrument. The higherbasis weight and the less beating time resulted in the bulkier structure and the less efficiency of heattransfer. The addition of the perlite powder as a filler resulted in the great increase in the heat insulation,although the addition of the calcium carbonate decreased the heat insulation potential of paper.
