Multi-Response Optimization of Skewing Carton Using Taguchi Method with Desirability Function Approach

Abstract

Abstract Rapid industrial developments have brought the new challenges for quality improvement in industrial competition. Packaging is an integral part of product presentation to attract consumer. Quality and innovation of the packaging are as important as the product itself. One of the quality characteristics of toothpaste carton packaging is skewing, which is measured by the angle and gap skewness of the cardboard. Skewing process optimization is influenced by several factors i.e. glue temperature, glue pressure, height of guide folding, carton varnish concentration, and carton UV intensity. In this research, the angle and gap skewness of the carton is optimized through various set factors experiment. The optimal experimental design is obtained using Taguchi method with desirability function approach. The results show that height of guide folding, glue temperature, and glue pressure contributed significantly to the effect of skewing. The optimum conditions is obtained by applying the 1500C glue temperature setting, 2 bar glue pressure, 8.3 mm guide folding height, 260 Cps carton varnish concentration, and UV intensity with 3 lamps.
