The global packaging industry is entering a new phase. For decades, packaging was judged mainly on cost, protection and convenience. Today, research shows that the focus is shifting towards verified sustainability, circular design and digital traceability.
The change is being driven by a combination of regulation, consumer expectations and technological innovation.

Packaging manufacturers, brand owners and retailers are facing growing pressure to prove environmental claims, improve recyclability and provide greater transparency across the packaging lifecycle.
Recent studies and industry research suggest that the era of broad sustainability messaging is giving way to a more evidence-based approach. In short, packaging is no longer just a container. It is becoming a measurable part of a company’s environmental and business strategy.
Regulation is raising the bar
One of the biggest forces behind the industry’s transformation is the European Union’s Packaging and Packaging Waste Regulation (PPWR). The regulation entered into force in 2025 and introduces requirements covering the entire packaging lifecycle, from design and material selection to recycling and reuse.
Its goal is to reduce packaging waste, increase circularity and ensure that packaging placed on the EU market can be recovered or reused more effectively.
The impact extends far beyond Europe. Any company selling packaged products into the EU market will need to meet the new requirements, making PPWR a significant influence on global packaging strategies.
Research presented across the packaging sector points to a growing shift towards so-called “fibre-first” solutions, with paper-based and barrier-paper packaging attracting increasing investment. Yet experts caution against assuming that one material is automatically more sustainable than another.
Lifecycle assessment is becoming the preferred method for measuring environmental impact because it evaluates emissions, resource use and end-of-life performance across the entire product lifecycle.
Recent academic research reinforces this point. A study from researchers at Michigan State University found that certain packaging materials can generate substantially lower greenhouse gas emissions than alternatives when assessed across their full lifecycle, highlighting the importance of evidence-based material selection rather than relying on assumptions alone.
At the same time, material innovation continues to accelerate. Researchers are developing biodegradable alternatives using unconventional feedstocks, including agricultural waste, shellfish by-products and fungal materials.
Early research from the University of Maine has demonstrated plastic-free packaging made from fungus-derived materials that could help extend food shelf life while reducing reliance on conventional plastics.
Consumers want proof, not promises
Consumer attitudes towards packaging are also evolving.
According to McKinsey’s 2025 global packaging survey, price and product quality remain the most important purchasing factors worldwide. When consumers evaluate packaging specifically, food safety and shelf life continue to rank above environmental considerations.
That does not mean sustainability has lost importance. Rather, consumers are becoming more selective and informed. McKinsey’s research found that recyclability is now viewed as the most important sustainability attribute in packaging across many markets, while broader environmental claims carry less influence.
Generational differences remain evident. Younger consumers, particularly Millennials and Generation Z, are generally more likely to consider sustainability when making purchasing decisions.
However, rising living costs and economic uncertainty mean value for money continues to dominate purchasing behaviour across most demographic groups.
Research also points to growing scepticism around environmental terminology. Consumers increasingly question vague labels such as “eco-friendly” or “biodegradable” when clear explanations are absent.
Industry studies show that many shoppers struggle to understand disposal instructions and are often uncertain about the environmental benefits of newer packaging materials.
For packaging companies, this creates a new challenge. Success depends not only on improving sustainability performance but also on communicating it clearly. Simple disposal instructions, transparent labelling and easily understood design cues are becoming as important as the material itself.
Smart packaging moves into the mainstream
Digital technology is becoming a central part of the industry’s response to regulatory and consumer demands.
Packaging companies are increasingly using artificial intelligence to accelerate material development, improve packaging performance and identify more sustainable design options.
AI tools are helping researchers evaluate complex combinations of materials and predict environmental outcomes more efficiently than traditional methods.
At the same time, machine-readable technologies such as QR codes and digital product passports are gaining momentum.
These tools allow companies to track packaging throughout its lifecycle, support regulatory reporting and provide consumers with information about recycling, reuse and product origin.
Industry researchers describe this trend as a move towards fully connected packaging systems, where physical packaging is linked to digital data throughout the supply chain. The approach supports circular economy objectives by making it easier to monitor material flows, verify compliance and improve recovery rates.
The result is a packaging sector that is becoming increasingly data-driven. Decisions that were once based primarily on cost and appearance are now being guided by measurable environmental performance, compliance requirements and real-time information.
The latest research suggests that the packaging industry’s future will be defined less by marketing claims and more by demonstrable outcomes.
Companies that can combine verified sustainability, innovative materials and digital traceability will be best positioned to meet evolving regulations and changing consumer expectations.
For packaging businesses worldwide, the message is becoming clear: sustainability alone is no longer enough. The next competitive advantage lies in proving it.
