In recent years, the FIBC (Flexible Intermediate Bulk Container) industry has increasingly turned to lean manufacturing principles to enhance operational efficiency. FIBC manufacturing, like garment production, is a well-established system that involves a complex array of essential processes. Key performance indicators in the FIBC industry include lead times, production output, waste reduction, and labor efficiency. To stay competitive globally, FIBC manufacturers prioritize reducing lead times and minimizing waste, both of which are crucial for boosting productivity and achieving sustainable development. This drive towards lean and responsive manufacturing has intensified the need for advanced tools and techniques to identify and address inefficiencies within production. This study explores the application of lean manufacturing tools in the Flexible Intermediate Bulk Container (FIBC) industry to improve productivity and reduce waste. As the industry faces increased global competition, FIBC manufacturers are under pressure to optimize lead times and eliminate inefficiencies to stay competitive. In particular, manufacturers are implementing lean methodologies such as Value Stream Mapping, Root Cause Analysis (RCA) to reduce rework rates, Kanban, standard minute value (SMV) and efficient methodologies to meet the expectations of a competitive market. This paper shows a case study of an FIBC company where lean tools are used systematically to identify and mitigate sources of waste throughout its production process. Initial results show that lean tools can lead to significant improvements in production rate, lower lead times, and enhanced operational stability.
