Packaging manufacturers facing PFAS restrictions and Net Zero mandates are rethinking material construction rather than waiting for drop-in chemical substitutes, according to Jack Eaton, Chief Commercial Officer at UK-based materials developer NIRI.

Writing on 25 June, Eaton framed the commercial problem in supply-chain terms: PFAS embedded in consumer goods survive recycling loops and contaminate secondary materials. PFAS in food packaging, for example, is not removed during repulping when consumers place the packaging in paper recycling bins. The contamination degrades recycled feedstock and complicates composting streams — a direct liability for any supplier selling into recycled-content packaging programs.

The regulatory drivers are specific. Eaton cited the UK's legally binding 2050 Net Zero target and international PFAS regulations as the forces shaping material roadmaps. He did not name individual jurisdictions' PFAS statutes, but the compliance logic holds across markets: any packaging supplier exporting into regulated regions must evidence PFAS-free constructions or face exclusion from recycling-compatible product lines.

Redesign, not replacement chemistry

NIRI's response to the PFAS problem is a shift from 2D to 3D material thinking — combining different layers and materials to build PFAS-free products through strategic material selection, construction design, and surface functionalisation research. Eaton's framing is notable for sourcing teams: the company is pursuing a design-led route rather than relying entirely on replacement chemistry, which remains the slower and more uncertain path for many PFAS applications such as grease barriers in food packaging.

The company is also working to reduce dependency on fossil- and petroleum-based inputs. Eaton said NIRI has focused on polymerisation capabilities, including renewable intermediates and fermentation-derived monomers, to produce bio-based nonwovens that address resource depletion and plastic pollution. He stressed that where recyclability and reusability are inherent in these materials, collaboration between nonwovens specialists and packaging manufacturers determines whether the sustainability gains carry through to the finished pack.

Energy as a procurement criterion

Eaton's most actionable points for buyers concern resource efficiency in manufacturing. Lightweight and mono-component materials cut material consumption while maintaining or enhancing performance, he wrote. The savings compound upstream and on the line: lighter materials require less thermal and mechanical energy to process, while fewer material types mean fewer process steps, fewer energy-intensive bonding operations, and fewer chemical inputs.

Mono-component systems also simplify end-of-life handling. Because recycling processes deal with a single polymer family rather than multi-material laminates, they reduce the energy cost of separation and reprocessing — the point at which many packaging formats currently fail recyclability assessments.

Eaton set out what packaging manufacturers should expect from a materials partner: in-depth energy audits, smart controls and sensors to optimise heating and cooling cycles in production, and AI tools for data-driven manufacturing optimisation. Strategic analysis of process capabilities and manufacturing workflows can pinpoint bottlenecks and energy hotspots, with layout, process sequence and resource scheduling adjustments reducing peak loads.

Scope 3 pressure reaches the converters

The harder commercial force is Scope 3. Eaton identified indirect emissions across the value chain — raw materials, logistics, and end-of-life impacts — as notoriously hard to track and evidence, and now the defining challenge for many packaging manufacturers and their clients. Customers, investors and regulators are all scrutinising energy strategies, he noted.

His proposed levers are concrete: material optimisation, lightweighting, and mono-component design to reduce raw material intensity and upstream emissions. These are measurable inputs a buyer can build into supplier scorecards, unlike broader circularity claims that lack a traceable standard.

Eaton closed by arguing the circular transition is no longer simply a compliance exercise but an opportunity to redesign materials, improve manufacturing efficiency and build resilient supply chains — combining nonwovens technologies with energy-conscious production and collaborative development from R&D through to market-ready product.

For sourcing teams, the decision this forces is straightforward: PFAS-exposed packaging specs and multi-material constructions now carry regulatory and Scope 3 risk that PFAS-free, mono-component nonwovens alternatives can retire — provided suppliers can evidence the energy audits and lifecycle data behind their claims.
