The paper focused on enhancing packaging efficiency in the Fast-Moving Consumer Goods (FMCG) sector, specifically for powder-form products. The primary challenge faced by FMCG companies is the precise filling of product packets during machine-based packaging. This paper explored the factors contributing to underfilling and overfilling and proposed techniques and strategies to improve packaging efficiency. The study employed causality analysis, multivariate regression, and statistical methods to uncover the root causes of packaging variations. The findings also highlighted the importance of reducing overfilling to minimize material wastage and environmental impact. Two key propositions were presented and examined in the paper in order to investigate and support the objective. The first proposition examined the impact of external environmental factors on packaging efficiency, including lump formation, temperature, humidity, and rainfall. The second proposition investigated the effect of time difference on packaging efficiency. The reduction of overfilling not only reduces material wastage but also aligns with sustainability practices, portrays companies as responsible environmental stewards and increases revenue for the company. This paper discussed some actionable recommendations for improving the packaging process, reducing waste, and enhancing industry efficiency. The findings have implications for similar products and contribute to the broader goal of sustainability.
