The Future of Packaging is Now: An Expert Interview on Sustainability, Smart Packaging, and Market Research in a Disrupted Industry

Introduction: Why Packaging Research Has Never Mattered More

The global packaging industry sits at a remarkable inflection point. Valued at approximately $1.05 trillion in 2023 and projected to grow at a CAGR of 4.5% through 2030, the sector is being simultaneously pressured by tightening environmental regulation, transformed by materials innovation, and reshaped by shifting consumer attitudes toward sustainability. From the EU's Packaging and Packaging Waste Regulation (PPWR) to extended producer responsibility (EPR) schemes proliferating across North America and Asia-Pacific, the policy environment is accelerating change at every level of the value chain.

To explore what these shifts mean for market researchers, we sat down with Dr. Helena Marsh, a fictional composite expert representing the perspectives of senior packaging market research practitioners, who has spent over two decades advising FMCG brands, material suppliers, and packaging converters on strategy and consumer insight. The following is an edited transcript of our conversation.

Setting the Scene: The State of the Packaging Market in 2024

You've been researching the packaging industry for over 20 years. How does today's environment compare to what you've seen before?

Dr. Marsh: Honestly, the pace of change is unlike anything I've experienced before. When I started out, packaging research was largely about consumer preference studies — which pack format do you prefer, what colour communicates freshness, does this label convey premium quality? Those questions still matter, but they've been layered on top of an entirely new stratum of complexity.

Today, every major FMCG brand I work with is dealing with a trilemma: how do you maintain consumer appeal, reduce environmental impact, and manage cost — simultaneously? And the challenge for researchers is that these dimensions often pull in opposite directions. A consumer might say in a focus group that they strongly prefer sustainable packaging, but revealed preference data from retail tracking tells a more nuanced story about what they actually buy when sustainable options carry a price premium.

"The gap between stated and revealed sustainability preference in packaging is one of the most persistent and commercially significant research challenges in the FMCG sector today." — Dr. Helena Marsh

Can you give us a sense of the scale of the sustainability challenge in packaging research terms?

Dr. Marsh: The numbers are stark. Euromonitor estimates that over 80% of consumers in developed markets say packaging sustainability influences their purchase decisions — but when you run conjoint analysis studies isolating willingness to pay for sustainable packaging attributes, the price elasticity is far more conservative. Nielsen's research has consistently shown that while consumers express strong environmental values, only a minority will pay more than a 5–10% premium for sustainable packaging before switching to the conventional alternative.

This disconnect has massive implications. Brands that price sustainable packaging purely on consumer stated preference research risk commercial disaster. The job of good research is to close the gap between what people say and what they do — and that requires mixed-methods approaches that combine qualitative depth with behavioural data and careful experimental design.

Methodological Approaches: What Works in Packaging Research

What methodologies do you find most effective for packaging research specifically?

Dr. Marsh: It depends enormously on the research question. For early-stage concept development — evaluating new materials, formats, or sustainability propositions — I favour a combination of qualitative ethnographic research and co-creation workshops. Watching consumers interact with packaging in naturalistic settings reveals so much that a survey or even a traditional focus group misses. How do they open it? Where do they store it? When do they dispose of it, and how do they feel about that disposal moment? These behavioural nuances are gold for packaging designers.

For later-stage validation and go-to-market decision-making, shelf simulation studies and virtual reality retail environments are increasingly powerful. Platforms like Perceptive and Medallia, as well as dedicated virtual store testing tools like Kantar's Shopperscope, allow us to test packaging performance in a realistic competitive context without the cost and logistical complexity of a physical store test.

And conjoint analysis — how central is that to packaging research today?

Dr. Marsh: Absolutely central for any packaging decision with a significant cost or sustainability trade-off. Adaptive choice-based conjoint (ACBC) is my preferred approach for packaging research because it handles the multi-attribute complexity well. You can simultaneously model consumer preferences across material type, recyclability signposting, format, size, price point, and brand information — and decompose the relative importance of each attribute at the segment level.

I worked on a project for a major European food manufacturer last year where we used conjoint to evaluate five different sustainable packaging formats for a chilled convenience food range. The model showed that clear recyclability labelling had nearly twice the preference impact of the actual material composition — consumers couldn't identify whether a pack was made from recycled content, but they could easily see and respond to a clear recycling symbol. That single insight redirected a significant packaging R&D investment decision.

Smart Packaging and the Research Frontier

Smart packaging — connected, intelligent packaging with embedded sensors or QR functionality — seems to be gaining real commercial momentum. What's the research picture here?

Dr. Marsh: Smart packaging is one of the most exciting and genuinely under-researched areas in the sector right now. The global smart packaging market was valued at around $38 billion in 2023 and is growing at a CAGR of approximately 8.2%. The use cases are compelling: time-temperature indicators for cold chain products, NFC-enabled packaging for brand authentication and consumer engagement, and active packaging that extends shelf life through oxygen scavenging or moisture regulation.

But the research challenges are significant. Consumer awareness of smart packaging functionality is still low — in studies I've conducted, fewer than 30% of consumers can correctly explain what an NFC-enabled pack does, even in tech-savvy demographics. There's a real consumer education challenge embedded in the adoption curve, and research must account for this when modelling market uptake. Companies like Amcor, Sealed Air, and Tetra Pak are investing heavily in this space, but commercialisation timelines depend on consumer uptake as much as technical feasibility.

Research in this area needs to be longitudinal — tracking awareness, understanding, and behavioural adoption over time rather than treating consumer readiness as a static variable.

Regulatory Impact and the Role of Industry Bodies

How significant is regulatory change as a driver of packaging research demand?

Dr. Marsh: It's become the dominant demand driver for research in Europe, without question. The EU's Packaging and Packaging Waste Regulation (PPWR), which is working through the legislative process, will mandate minimum recycled content levels, phase out certain single-use formats, and require all packaging to be reusable or recyclable by 2030. For any brand selling into the European market, understanding consumer response to compliant alternatives — and the competitive implications of compliance strategies — is a board-level priority.

Industry bodies like EUROPEN (the European Organisation for Packaging and the Environment), CEFLEX (the circular economy for flexible packaging), and the Sustainable Packaging Coalition in North America are publishing increasingly sophisticated guidance on research-based approaches to assessing packaging sustainability credentials. Researchers who engage with these bodies' methodological frameworks will produce more credible, industry-accepted outputs.

"Regulatory change is the most reliable demand generator for packaging market research. When legislation forces reformulation, brands need insight to navigate consumer response — and they need it urgently."

Advice for Market Researchers Entering the Packaging Sector

What advice would you give to a market researcher new to the packaging industry?

Dr. Marsh: Three things. First, understand the supply chain before you design your research. Packaging decisions involve material suppliers, converters, brand owners, retailers, and end consumers — and insight from each layer tells a different part of the story. The best packaging researchers I've seen think in systems, not in isolated audience snapshots.

Second, get comfortable with the intersection of sustainability and commercial reality. You'll be asked to quantify consumer valuation of sustainability attributes constantly, and you need methodological rigour — particularly around revealed versus stated preference — to avoid producing findings that set unrealistic expectations.

Third, embrace materials science literacy. You don't need to be an engineer, but understanding the difference between mono-material flexible packaging and multi-layer laminates, or why the recyclability of bioplastics is more complicated than marketing materials suggest, will make your research designs far more credible with technical stakeholders.

The packaging industry rewards researchers who can translate consumer and commercial insight into decisions that account for the physical and regulatory constraints of real-world packaging systems. That's a harder brief than many realise — but it's also what makes it endlessly fascinating.

Conclusion: Research as a Strategic Asset in Packaging's Transformation

As Dr. Marsh's insights illustrate, the packaging industry is navigating a transformation that touches every dimension of research practice — from methodology to stakeholder management to the fundamental questions being asked. With sustainability regulation tightening, smart packaging gaining commercial traction, and consumer attitudes evolving at pace, the demand for high-quality, methodologically rigorous packaging research has never been greater. Researchers who invest in sector-specific knowledge, mixed-methods capability, and a sophisticated understanding of the stated-revealed preference gap will be exceptionally well positioned to add value in this dynamic, high-stakes industry.
