This study aims to improve the quality and innovation of coffee powder packaging design by applying the Theory of Inventive Problem Solving (TRIZ). TRIZ provides a systematic framework for identifying and resolving design challenges by utilizing inventive principles derived from patent analysis. The research focuses on solving key issues in coffee packaging, including air leakage, degradation of product quality during storage, and difficulties in usability. The methodology involves problem identification, TRIZ analysis, concept development, prototyping, and performance evaluation. The prototype was developed using biodegradable multilayer materials and featured a zip-lock closure system for enhanced usability and product preservation. Key TRIZ principles applied include segmentation, local quality, flexibility, and the use of new materials. Evaluation results show that the new packaging design extended product freshness by up to 30% compared to conventional packaging. This research contributes to the field of sustainable packaging innovation by demonstrating the applicability of TRIZ in small business contexts such as coffee SMEs. It offers both theoretical insights and practical solutions for product packaging that are functional, environmentally friendly, and aligned with consumer expectations. The findings have implications for improving product competitiveness and advancing innovation practices in the food packaging industry.
