How Package Design Testing Identified the Winning Pack

Background

A leading FMCG brand wanted to evaluate two new packaging concepts, Premium and Finely Cut, to determine which design would perform better on shelf and drive stronger purchase intent. Instead of relying on internal opinion, the brand commissioned a structured package testing study combining eye tracking research and consumer insight analysis.

The objective was to measure visual attention, brand fit, relevance, and purchase likelihood before finalizing production.

Research Approach

Eye Tracking and Behavioral Metrics

The study used eye tracking metrics such as Time to First Fixation and Earned Attention to measure how quickly and how long consumers looked at key elements including the brand logo, top panel, and warning area . This allowed the team to assess on-shelf visibility and attention capture.

Stated KPI Evaluation

Alongside behavioral data, both pack designs were evaluated on Likeability, Appeal, Relevance, Brand Fit, and Purchase Intention. This ensured packaging decisions were supported by both visual performance and consumer perception data.

Key Findings

Faster Attention Led to Stronger Salience

Across both Red and Blue variants, Finely Cut captured attention faster and sustained gaze longer compared to Premium. Lower time to discovery and higher earned attention indicated stronger visual cut-through in retail environments.

Higher Purchase Intent Across Segments

Finely Cut outperformed Premium across core KPIs. For Red Label, Purchase Intention reached 70 percent versus 53 percent for Premium . For Blue Label, Purchase Intention was 70 percent compared to 50 percent for Premium. Likeability and Brand Fit also showed consistent uplift for Finely Cut.

Stick Design Reinforced the Pack Advantage

Stick design testing revealed that specific stick variants under Finely Cut strengthened perceptions of modernity and improved willingness to purchase. This demonstrated that package design testing should assess the full product bundle, not just the outer pack.

Business Impact

The study provided a clear design direction backed by behavioral data. By identifying the stronger packaging concept before launch, the brand reduced risk, improved internal alignment, and increased confidence in go-to-market decisions.

Even a double-digit lift in purchase intent at scale can translate into meaningful commercial impact, particularly in competitive categories where packaging drives first moment influence.

Conclusion

This case demonstrates how structured package testing and eye tracking research can transform packaging decisions from subjective debate into measurable strategy . By combining visual attention analysis with purchase intent evaluation, the brand identified a clear winning pack and strengthened its shelf performance outlook.

For brands planning redesigns or product launches, data-driven package design testing provides clarity, reduces uncertainty, and supports scalable growth decisions.
