Opening of Perforated Folding Cartons: From the Field to Testing
Di Wang, Changfeng Ge · Packaging Technology and Science · 2016
This study demonstrates how a human‐hand opening process for a perforated folding carton can be mapped into a path for testing. A field observation was conducted to visually record opening patterns by an observation group. The most representative opening pattern was then repeated by another observation group in the laboratory, and the resulting opening pattern and movements were captured and mapped mathematically via Matlab. The opening speeds were calculated based on opening path that is used to compare the testing machine. A fixture attempting to mirror the opening path was developed for perforated folding cartons to be tested by using tensile testing machine. The study suggested that the process, involving the identifying opening pattern, guided test and fixture equipped testing, can be applied to replication of human‐packaging interaction.
