We present a holistic and comprehensive approach to achieving fluid package compatibility of liquid products. In general, liquid products follow a sequential design process where the fluid formulation is established first, followed by the design of the package. We propose the formulation and package be designed in parallel to achieve a comprehensive understanding of component interdependencies. To demonstrate this approach, we have developed a holistic design framework that incorporates both formulation and package components. Two interrelated models are proposed to describe the formula-pack system. A micro-structure based model describes the formulation rheology and a first principle fluid dynamic model describes the fluid-pack interaction. Modifying formula ingredient levels impacts the rheological model while modifying geometric package parameters impacts the fluid dynamic model. Together, the two models describe the entire liquid product system and map the impact of parameters from both product components. Ultimately, an integrated methodology for holistic liquid product design enables accelerated learning cycles and greater exploration of possible designs, providing the consumer with a superior experience.
