EN 18120: CEN Design-for-Recycling Standards & PPWR
EN 18120: The New CEN Design-for-Recycling Standards — What Plastic Packaging Converters Must Do Now
On April 15, 2026, the European Committee for Standardisation (CEN) published the EN 18120 series — fourteen design-for-recycling standards covering virtually every plastic packaging format on the EU market, from PET bottles and PP tubs to flexible PE films and EPS boxes. For the first time, Europe has a single, harmonised technical language for deciding whether a plastic pack is designed for recycling — the language the European Commission is expected to write into the Regulation (EU) 2025/40 Article 6 delegated acts due by January 1, 2028.
For printers and converters, this is not an abstract standardisation story. EN 18120 will decide how every film, tray, bottle, sleeve and closure you produce is graded A to C under Annex II — and whether it survives the below-Grade-C market ban on January 1, 2030. The fragmented landscape of RecyClass protocols, Cyclos-HTP assessments and national guidelines that converters have navigated for years is being consolidated into one CEN reference, and national standards bodies must adopt it and withdraw conflicting guidance by October 2026.
What the Regulation Actually Says
PPWR Article 6 requires all packaging placed on the EU market to be recyclable. From August 12, 2026, that means a documented recyclability assessment feeding the Article 39 Declaration of Conformity with the Annex VIII technical file. From January 1, 2030, packaging must achieve at least recyclability grade C under Annex II (design-for-recycling), with below-Grade-C packaging banned from the market; from January 1, 2038, only grades A and B remain. Article 6(4) tasks the Commission with adopting delegated acts establishing the design-for-recycling criteria and the grading methodology per packaging category by January 1, 2028.
The PPWR explicitly requires the Commission to take account of harmonised European standards when defining those criteria. That is where EN 18120 comes in: the series was developed under the Commission's M/584 standardisation request (issued in 2022) precisely to give the delegated acts a ready-made technical foundation. In plain terms: the PPWR defines what converters must achieve; EN 18120 defines how compliance will be measured and verified.
The EN 18120 Series, Part by Part
CEN structured the series by resin and format, with a deliberate split between design guidelines (the proactive design rules engineers apply at the spec stage) and evaluation protocols (the formal test methodologies that verify a finished construction). Converters need both: guidelines to design, protocols to prove.
| Part(s) | Scope | What It Covers for the Converter |
|---|---|---|
| Part 1 | Definitions & principles | Common terminology for design-for-recycling of plastic packaging — the vocabulary the delegated acts will reuse |
| Part 3 | Sortability evaluation | NIR detectability of the whole pack: carbon-black pigments, full-coverage sleeves, incompatible coatings and adhesives that send packs to the reject stream |
| Parts 4, 5, 10, 11 | Rigid PET | Guidelines and protocols for PET bottles and non-bottle rigid PET (trays, punnets, clamshells) |
| Parts 6, 8, 12, 14 | Rigid PE, PP & PS | Guidelines and evaluation protocols for rigid polyolefin containers, tubs, closures and polystyrene formats |
| Parts 7, 13 | Flexible PE & PP | Design guidelines (Part 7) and evaluation protocols (Part 13) for mono-PE and mono-PP films and laminates — project-led by CEFLEX |
| Parts 9, 15 | EPS | Guidelines and protocols for expanded polystyrene packaging, including cold-chain and protective formats |
CEFLEX, which led the flexible packaging parts, fed in evidence from its Phase 2 testing programme — more than 600 representative flexible packaging samples tested across independent European laboratories, generating over 1,700 data points on sortability and mechanical recyclability. The standards are therefore not theoretical: they encode what actually survives Europe's sorting and reprocessing infrastructure.
What Changes for Converters
1. One Reference Replaces a Fragmented Landscape
Until now, a converter qualifying a new film or tray faced a patchwork: RecyClass design-for-recycling guidelines and certification, Cyclos-HTP assessment, national guidance such as the French CEREC or German ZSVR minimum-standard catalogues, and brand-owner-specific scorecards. EN 18120 does not make the industry protocols worthless — RecyClass and Cyclos-HTP assessments remain the practical certification routes today, and both organisations contributed to the CEN work — but the CEN series becomes the formal reference the delegated acts will cite. Converters should expect RecyClass and Cyclos-HTP protocols to converge on EN 18120 terminology and thresholds over the next revision cycles.
2. The October 2026 National Adoption Deadline
CEN rules give national standardisation bodies six months to implement the series: by October 2026, DIN, AFNOR, UNI, AENOR and their counterparts must publish EN 18120 as national standards and withdraw conflicting national guidelines. For converters selling cross-border, this is quietly significant — the national recyclability guidance your customers' technical teams reference in specifications will be superseded by identical EN documents in every Member State.
3. Sortability Becomes a First-Class Test
Part 3 elevates sortability — long the hidden killer of theoretically recyclable packs — to a standardised evaluation. A mono-PP tray with a carbon-black masterbatch, a PET bottle with a full-coverage shrink sleeve, or a PE film with an NIR-opaque metallised layer can be perfectly reprocessable and still fail, because the sorter never routes it to the right bale. Converters should expect Annex II grading to weight NIR detectability heavily, and should re-check every dark or decorated SKU against Part 3 methodology.
4. Guidelines at the Spec Stage, Protocols at Qualification
The guideline/protocol split maps directly onto converter workflow. The guideline parts (6, 7, 8 and related) belong in your structure design and prepress stage — material choices, barrier selection, ink coverage, adhesive chemistry, closure compatibility. The protocol parts (12, 13, 15 and related) belong in your qualification file: they define the laboratory tests whose reports go into the Annex VIII technical documentation behind each Declaration of Conformity. A converter who designs against the guidelines but never books the protocol tests has only half a compliance story.
5. The DoC Evidence Chain Gets a Standard Citation
From August 12, 2026, every Declaration of Conformity needs documented recyclability evidence. Until the delegated acts land, converters and brand owners have been improvising the evidence base — RecyClass certificates, lab reports, supplier declarations. EN 18120 gives that file a citable backbone: a DoC supported by an EN 18120 protocol test report is materially stronger in front of a market-surveillance authority than one supported by an internal assessment alone.
Practical Action Plan
- Buy the relevant parts now. The standards are available through national standards bodies (DIN, AFNOR, UNI, AENOR, etc.). A flexible converter needs Parts 1, 3, 7 and 13; a rigid-container converter needs Parts 1, 3, 6, 8, 12 and 14; a PET tray or bottle converter needs Parts 1, 3, 4, 5, 10 and 11.
- Map your portfolio against the guideline parts. Re-run the design review on every active construction — substrate, barrier, ink coverage, adhesive, closure, decoration — and flag deviations from the EN 18120 design rules alongside your existing RecyClass or Cyclos-HTP status.
- Re-screen sortability per Part 3. Prioritise dark-pigmented SKUs, full-coverage sleeves and metallised constructions. Swap carbon black for NIR-detectable pigments where flagged.
- Book protocol testing for borderline references. Constructions you expect near the grade C threshold need laboratory evidence first — they carry the 2030 ban risk.
- Cite EN 18120 in your DoC technical files. Update Annex VIII documentation templates so recyclability evidence references the relevant EN 18120 part, test date and lab.
- Track the Article 6 delegated acts. The grading methodology lands by January 1, 2028; expect it to lean on EN 18120. Constructions aligned with the standards today face the smallest re-qualification effort tomorrow.
How PPWR Connect Helps
EN 18120 turns design-for-recycling from a patchwork of voluntary protocols into the technical backbone of PPWR Article 6 — and it multiplies the documentation a converter must hold per SKU. PPWR Connect lets converters inventory every active construction, record the EN 18120 parts, test reports and RecyClass or Cyclos-HTP certificates behind each recyclability claim, flag SKUs that fail sortability or sit below the grade C line for 2030, and generate audit-ready Declarations of Conformity with the Annex VIII evidence chain attached. With national adoption due by October 2026 and the August 12, 2026 deadline weeks away, converters who anchor their compliance files to the new standards now will answer brand-owner RFQs that competitors cannot.
