In response to the challenges of lengthy modeling cycles and high trial-and-error costs in traditional fast-moving consumer goods (FMCG) packaging design, a collaborative application model integrating Artificial Intelligence Generated Content (AIGC) and Virtual Reality (VR) technologies was explored to enhance design efficiency and market adaptability. Taking Guangdong herbal cool tea packaging design as a practical case, a three-phase workflow of AIGC-driven creative generation - VR simulation modeling-market prediction validation was developed by integrating technological tools including Deepseek, Midjourney, IC3D, and Package Design AI. The result demonstrates that the new workflow significantly reduces design cycles, with market preference prediction scores for three design proposals (4.1002, 4.0873, 4.0693) surpassing the industry benchmark (4.0602), thereby validating the efficacy of the technological integration. The synergistic application of AIGC and VR technologies enables end-to-end digital reconstruction of FMCG packaging design, spanning from demand insight to solution validation. This framework provides a replicable methodology for high-frequency iterative packaging design in the FMCG sector, while facilitating the transformation of designers’ roles toward strategic and systemic innovation.
