摘要

A new design of carton compression experiment for the lab course of packaging materials was developed for the undergraduate students to study the influence of dimensions including perimeter, length-width ratio and height of cartons on their compression strengths. The students are divided into groups. Each group designs an experiment to study the influence of one dimension factor. All the testing should be finished in two credit hours and the groups take turns to use the instruments. They are asked to operate the instruments independently with the guide of operation manuals. Determined values were compared with calculated values derived from Kellicutt formula. Detailed analysis of the influence should be made. The students are asked to purchase the desired cartons directly from the carton plant, which makes them to get familiar with real-life carton market. A pretest showed that this design was feasible. By doing this experiment, the students can fully explore their social and academic abilities. Thus this new design is meaningful.
