Development and Evaluation of RFPs for Bamboo Shoot Products Through Drop Testing

Abstract

Packaging functionality not only differentiates food products but also conveys brand identity. With increasing demand for shelf-stable and convenient products like bamboo shoot meals, innovative packaging is crucial. However, limited research evaluates the durability of Retortable Flexible Pouches (RFPs) through drop tests. This study assessed RFPs durability using performance drop tests. Consumer preferences were analyzed through a questionnaire, and the packaging design was developed using Adobe Photoshop. Data analysis was conducted using IBM SPSS Statistics 27, and drop tests were performed according to ASTM standards. A gusset folder box was designed to contain RFPs products, which were Sample A (dry-textured bamboo shoots) and Sample B (wet-textured bamboo shoots). Each sample was cushioned with single-layer bubble wrap, double-layer bubble wrap, or inflatable air bubbles and dropped in six positions: top, bottom, right, left, right, and left corner sides. G values, measuring impact stress, were recorded during the tests. Findings showed 68% of respondents preferred medium-sized packaging (250g–500g), 72% favored freshness designs, 65% prioritized informative labeling, and 58% preferred high-quality imagery. Although medium-sized packaging was preferred, a 100g quantity was developed as suitable, balancing product characteristics, functionality, and effective sterilization. Inflatable air bubbles emerged as the most effective cushioning material, recording the lowest G values (28 G for Sample A and 29.6 G for Sample B). In contrast, the top side recorded the highest G values (364.4 G for Sample A and 358.2 G for Sample B with single-layer bubble wrap). These results highlight inflatable air bubbles’ effectiveness in protecting RFPs of bamboo shoot products.
