Packaging Claims Are Materials Science Claims
"Recyclable" is a statement about caps, labels, adhesives, inks, coatings, and your customer's local recycling plant — not just the bottle.
Packaging claims look simple because packaging looks simple. It is not. A "recyclable" pouch, a "compostable" wrap, a "PFAS-free" tray — each of these is a claim about a layered material system, and the layers nobody mentions are usually where the claim breaks.
Three familiar examples
The PET bottle. The bottle body is among the most recyclable packages on earth. But the claim covers the whole unit: a PVC shrink sleeve can contaminate the stream, some pigments and barrier additives disrupt sorting, and the label adhesive matters. "100% recyclable" is a claim about every component — US FTC guidance says so explicitly.
The composite film. A crisp packet or coffee pouch that feels like plastic is often plastic-aluminium-plastic. Multi-material laminates are exactly what most recycling systems cannot separate — which is why films carry some of the highest claim risk per square centimetre in packaging.
The paper wrap. Paper reads as virtuous. But grease-proof paper historically achieved its performance with fluorinated coatings — and intentionally added PFAS in food packaging is now restricted by state law in Maine, Minnesota, and California, on differing timelines with differing definitions. A hidden barrier layer can also quietly break a recyclability or compostability claim. The coating may be a few percent of the mass and all of the risk.
The local-reality problem
Even a perfectly designed mono-material pack meets geography: the US FTC position is that an unqualified "recyclable" needs facilities available to a substantial majority of the customers where the product is sold. Public tools like the US EPA's WARM model can inform end-of-life comparisons, but access data for YOUR markets is part of the evidence, not an optional extra.
The rules, briefly
In the US, the FTC Green Guides address recyclable (§260.12), recycled content (§260.13), compostable (§260.7), and free-of claims (§260.9). In the EU, Directive 2024/825 covers the claim language from September 27, 2026, and the new Packaging and Packaging Waste Regulation ((EU) 2025/40, published January 22, 2025) sets design-for-recyclability requirements that phase in from 2030 — a design regulation rather than a claims rule, but it will shape what "recyclable" credibly means on EU shelves. State PFAS laws add a third, chemistry-specific layer in the US.
Reviewing like a challenger
A challenger does not read your marketing; they read your bill of materials. Body, closure, label, ink, adhesive, coating, liner — then the end-of-life route in the real markets. That is the review worth doing before print, because it is the review someone else will eventually do after.
Packaging claims are whole-system claims: every layer — cap, label, adhesive, ink, coating, liner — plus local end-of-life reality must support the words. The smallest layer is often the largest risk.
What this means for brands
- Get the full bill of materials, including coatings and adhesives, before approving any packaging claim.
- For 'recyclable' in the US, hold facility-access evidence for the markets you actually sell in.
- Paper with grease resistance deserves a PFAS question by default — state laws differ on definitions and dates.
- Design decisions made now will meet the EU's design-for-recyclability requirements phasing in from 2030.
Founder’s Vision
Evisentra's packaging review should be layer-level: product, package, closure, label, ink, adhesive, coating, liner, and end-of-life route — each with its own evidence line. A tiny coating may barely change a carbon footprint and completely change whether a public claim is defensible. Materials science is not a complication of packaging claims; it is what packaging claims are made of.
