PPWR & Paper Cup Converters: Aqueous Coatings, PFAS-Free Hot Cups & the Article 25 HORECA Ban

PPWR & Paper Cup Converters: Aqueous Coatings, PFAS-Free Hot Cups, Mono-Material Cold Cups and the Article 25 HORECA Ban

Paper cup forming is one of the most exposed sub-segments of the European packaging print industry under Regulation (EU) 2025/40. A hot cup for coffee, a cold cup for soft drinks, an ice-cream tub, a soup container, a vending cup — every one of them lives at the collision point of Article 6 (recyclability grading), Article 5 and Annex V (PFAS and heavy-metal restrictions), Article 7 (recycled content of any plastic component), Article 10 (minimisation), Article 25 and Annex V (single-use plastic format bans), Article 29 (reuse targets) and Article 39 (Declaration of Conformity). A paperboard cup is fibre on the outside, but a PE-extruded or PLA-laminated interior coating drags the whole construction below the deinkable / repulpable threshold — and that is the single technical lever that converters have to pull before August 12, 2026.

This guide is written for the cup-forming converter: the company running the Michael Hörauf, PMC, Marbach or Korean Paper Cup Machinery lines, ordering polyethylene-extruded cup-stock from Stora Enso, Metsä Board, BillerudKorsnäs, Sappi or WestRock, decorating in flexo or offset, and shipping finished hot and cold cups to coffee chains, QSR brands, vending operators and institutional caterers. PPWR will reshape the cup-stock specification, the coating chemistry, the lid bill of materials and the customer-facing data file at the same time.

What PPWR Actually Says About Paper Cups

Paper cups are packaging within the meaning of Article 3(1) and fall fully in scope. The regulation does not exempt them on the grounds of being fibre-based: the cup body is classified as “paper packaging” only when its non-fibre content stays below 5% by weight (Annex II, definition of paper-based composite packaging). A standard 12 oz hot cup with a 28 g/m² PE extrusion on a 250 g/m² SBS board sits at roughly 10% non-fibre content. Today it is therefore not graded against the CEPI / 4evergreen paper recyclability protocol — it is graded as a composite, and almost every PE-coated construction lands at grade C or below.

The implication is brutal. Under Article 6(4) and the 1 January 2030 horizon, packaging below grade C is banned from placement on the EU market. Under the higher floor that applies from 2038, only grades A and B can be placed at all. A polyethylene-coated hot cup is, on paper, a stranded asset. Either the coating chemistry migrates to a fibre-friendly aqueous dispersion (and the unit re-grades as paper, with non-fibre content under 5%) or the construction must be a mono-plastic cup graded as plastic under RecyClass REP-PP-01 or REP-PET. Cup converters that do not commit to a coating-migration path now will not have a sellable book of business in 2030.

The PE / PLA Grade-Killer and the Aqueous Dispersion Migration

The cup industry has spent the last decade pushing PLA bioplastic as the “green” alternative to PE. Under PPWR that position has collapsed. PLA is classified as plastic under the Single-Use Plastics Directive 2019/904 and remains plastic in the eyes of the recyclability protocol — it does not repulp cleanly in a CEPI v3 (February 2025) or 4evergreen REP v2.0 (January 2025) test and routes to the same reject stream as PE. Bio- sourcing does not move the grade. The only chemistry that gets a paper cup back into the fibre stream is a water-based aqueous dispersion barrier coating thin enough to keep non-fibre content under 5% and engineered to release cleanly during repulping.

Suppliers are now public with credible offerings: Michelman's VaporCoat 2200R and 2300R for hot cups, Solenis TopScreen barrier dispersions, BASF Joncryl HPB, Kotkamills ISLA AEGLE board, Stora Enso Cupforma Natura Solo, Metsä Board MetsäBoard Pro FBB Aqua-coated and Sappi Parade Recyclable Coffee Cup. Each requires re-qualification of the cup-forming line because the sealing curve, the rim-curl behaviour and the cup-sealing induction profile are all different from a PE extrusion. The grease and water-vapour transmission performance is generally adequate for hot beverages up to 90 °C and for chilled formats up to four hours; ice-cream and frozen formats remain the hardest case.

Operators should target three pieces of evidence per cup SKU before submitting the Declaration of Conformity under Article 39: a CEPI Recyclability Laboratory Test (v3) report showing > 80% fibre yield, a 4evergreen REP v2.0 evaluation placing the unit in Category A or B, and an INGEDE Method 11 deinkability and Method 12 stickies / repulpability report. Without all three, a brand-owner procurement team will not accept the cup for the 2026 launch window.

PFAS Elimination on Hot-Cup Interior Coatings

Article 5 read with Annex V prohibits intentionally added PFAS in food-contact packaging from August 12, 2026, with thresholds of 25 ppb for any individual PFAS, 250 ppb for the sum of measured PFAS and a 50 ppm ceiling on total fluorine. Fluorinated greaseproof treatments have already been wound down from most European cup-stock by major mills, but residual fluorine may still appear in older inventory, in release agents on hot-cup forming dies and in some imported cup-stock from outside the EU. Cup converters must run total-fluorine testing (ASTM D7359 or EPA Method 1633) on incoming board and on the finished cup to clear the 50 ppm threshold. The Article 39 DoC must declare the cup as PFAS-free at the molecule level, with mill declarations covering every layer of the construction.

Cold Cup Variants: PET-Lined, Mono-PP and PLA

Cold cups split the converter base. The dominant European cold-cup constructions are paperboard with PE coating (now the same grade-C problem as hot cups), mono-PET cups formed from thermoformed sheet (RecyClass REP-PET v6 — graded as plastic, food-grade rPET supply is the constraint), mono-PP cups (RecyClass REP-PP-01 v6.1.0 — graded as plastic, the carbon-black NIR detection rule applies to dark pigments) and PLA cups (Article 9(2) compostability carve-out remains in scope but does not include this format because PLA cups do not appear in the closed list of compostable formats permitted under the delegated act). PLA cold cups must therefore migrate to mono-PET or mono-PP rPET / rPP and be graded as plastic, or migrate to paper with an aqueous dispersion barrier and be graded as paper. There is no third route under PPWR.

Article 25 HORECA Ban: What Dies, What Survives

Article 25 read with Annex V Table 1 bans single-use plastic packaging for food and beverages filled and consumed within the premises of the HORECA sector from January 1, 2030. A coffee bar that serves espresso in a single-use cup to a customer drinking on the premises has only three legal options: dishwasher-washable porcelain or glass, a deposit-and-return reusable polypropylene cup system, or a single-use paper cup graded as fibre packaging (i.e. non-fibre under 5% via aqueous dispersion). PE-coated paper cups are not exempt — they are plastic-coated under Annex V's reading. Takeaway and delivery formats stay legal but feed into the reuse trajectory below.

For the converter, that creates two parallel order books. Single-use takeaway and vending cups remain a high-volume segment, but the in-premises HORECA pool migrates either to reusables (a closed-loop business won by injection-moulded PP cup suppliers such as Berry, Klean Kanteen and Vytal) or to aqueous-dispersion fibre cups. Cup-forming plants that hold only PE-extruded cup-stock will lose share to converters that have qualified an aqueous cup-stock by Q4 2026.

The Reuse Trajectory

Article 29 sets the reuse trajectory across the takeaway and delivery channel that remains legal for single-use beyond 2030. From February 11, 2027 (twenty-four months after entry into force), HORECA operators must allow consumers to bring their own reusable container for hot and cold drinks at no extra cost. From February 11, 2028, operators must offer a reusable packaging option for hot and cold beverages and ready-made food. From January 1, 2030, large food-service providers must hit a 10% reusable-packaging share for beverages; this rises through the 2030s under delegated acts still pending. Converters that can supply both the surviving single-use line (aqueous fibre cup) and a reusable mono-PP cup with a brand-owner deposit ID printed on the sidewall capture both pools.

The Lid, Sleeve, Straw and Secondary Stack

Every paper cup ships with at least one ancillary component, and each must be graded independently in the Annex II + Annex VIII multi-component logic. The hot-cup lid is almost always PS or PP — PS is not banned outright but is functionally non-recyclable in most Member State streams and is being phased out by chain operators. PP lids graded under RecyClass REP-PP-01 v6.1.0 are the dominant migration target; ABMC, Solo and Huhtamaki all publish mono-PP sip-lid SKUs. The lid must also retain a tethered closure under Article 6(4) and the Single-Use Plastic Directive 2019/904, which for paper cups means a hinged drink-aperture seal staying attached to the lid body. Cup sleeves (corrugated E-flute) grade independently as paper. Straws are PPWR-out-of-scope insofar as they are not packaging, but their plastic-ban status under the SUP Directive still constrains the bundled SKU. Carry-out carriers (paperboard cup trays) are themselves Annex II Category 1 fibre packaging.

Article 7 Recycled Content and Article 10 Minimisation

For the fibre portion of the cup, Article 7 recycled-content targets do not bite directly (fibre is excluded from the 2030 plastic recycled-content targets), but for the lid, the cup-base ring or any plastic ancillary, the 2030 thresholds apply: 30% rPP for non- contact-sensitive PP packaging, 10% rPP for contact-sensitive PP. The lid is contact- sensitive because the consumer's mouth touches it during drinking. ISCC PLUS mass- balance certificates from SABIC TruCircle, LyondellBasell CirculenRevive and Borealis Bornewables are the operational route to clear the threshold without compromising food- contact qualification under Regulation (EU) 10/2011 and the EFSA opinion on mechanical rPP for food contact.

Article 10 minimisation forces the converter to document why the chosen grammage, sidewall thickness and cuff design are at the minimum needed for function. Cups that carry decorative cuffs, double-walled insulating air pockets or oversized rims face a burden of proof: the design rationale must be recorded in the Annex IV minimisation dossier and presented on inspection. Single-walled cups with corrugated paper sleeves sold separately tend to clear minimisation cleanly; double-walled or air-pocket cups need a documented thermal performance justification.

Action Plan for Paper Cup Converters

1. Qualify an aqueous-dispersion cup-stock on at least one cup-forming line before Q4 2026. Run a side-by-side trial against the incumbent PE-extruded board, with rim-curl, sidewall-seal, bottom-seal and leak-test data on file. Pick one supplier from Kotkamills, Stora Enso, Metsä Board, Sappi or BillerudKorsnäs and commit volume.
2. Book CEPI v3, 4evergreen REP v2.0 and INGEDE Method 11 + 12 tests on each new cup reference. Archive the reports in a per-SKU compliance folder, indexed for export to the Annex VIII Declaration of Conformity.
3. Eliminate PFAS at the molecule level. Run ASTM D7359 total-fluorine screening on every incoming cup-stock lot and on the finished cup. Demand mill-level PFAS-free declarations covering coatings, sizing agents and release papers.
4. Migrate the lid to mono-PP RecyClass REP-PP-01 v6.1.0. Eliminate PS, EVA slip masterbatches and any carbon-black colourant; specify NIR-detectable dark pigments (Ampacet REC-NIR-BLACK, Cabot Plasblak NIR, Tosaf NIR-Black). Verify the tethered drink- aperture seal under Article 6(4).
5. Lock ISCC PLUS mass-balance rPP supply for the lid and any plastic components ahead of January 1, 2030; the 30% threshold for non-contact-sensitive PP and 10% for contact-sensitive PP applies to every PP component in the cup stack.
6. Build a reusable mono-PP cup variant with a brand-owner deposit ID printed on the sidewall. The Article 29 HORECA reuse mandate from January 1, 2030 is a new revenue line, not a threat — converters that can supply both single-use aqueous fibre and reusable mono-PP capture both pools.
7. Stand up a structured DoC / DPP data pipeline per SKU: board grade, grammage, fibre origin, FSC / PEFC certificate, coating chemistry, coat weight, deinkability rating, ink chemistry, lid material, recycled-content mass-balance certificate, PFAS test report, CEPI / 4evergreen grade. PDFs will not scale beyond a few hundred references; brand-owner procurement now wants machine-readable spec sheets.

How PPWR Connect Helps Paper Cup Converters

Cup forming is one of the few packaging segments where a single chemistry decision — PE extrusion versus aqueous dispersion — flips the unit from grade C (banned 2030) to grade A or B (fully compliant through 2040). PPWR Connect gives hot-cup, cold- cup, ice-cream-tub and vending-cup converters a single platform to inventory every active construction, run automated Annex II grading on the full board + coating + lid + sleeve stack, intake CEPI v3, 4evergreen REP v2.0 and INGEDE test reports, track PFAS-elimination evidence at the molecule level, log ISCC PLUS rPP volumes against the Article 7 trajectory, model the Article 25 in-premises HORECA ban impact per customer account, and produce per-SKU Declarations of Conformity ready for Member State enforcement. Converters use the same platform to publish machine-readable component specifications back to their coffee-chain, QSR and vending-operator customers — turning PPWR compliance from a reporting burden into a tender-winning differentiator. With August 12, 2026 less than three months away, the cup-forming plants that lock down aqueous cup-stock qualification and mono-PP lid migration today are the ones that will hold their job book through 2030 and beyond.
