PPWR Countdown: The EU Declaration of Conformity Mandates Sustainable Packaging by August 2026

The New Regulatory Reality for Packaging in Europe

The countdown has officially accelerated for the global packaging industry. Starting August 12, 2026, the European Union Packaging and Packaging Waste Regulation (PPWR) – formally Regulation (EU) 2025/40 – introduces an unprecedented compliance threshold: the EU Declaration of Conformity. Any company manufacturing, importing, or distributing packaging within the EU market will be legally required to prove the sustainability and regulatory compliance of their products through strict technical documentation.

This mandate marks a paradigm shift. Sustainability is no longer just a corporate social responsibility goal or a marketing claim; it is a rigid legal and technical requirement. Without a valid Declaration of Conformity, packaging will simply be banned from the European market, potentially causing massive supply chain disruptions and significant fines.

What is the EU Declaration of Conformity?

The EU Declaration of Conformity (DoC) is a written, legally binding document issued by the manufacturer or importer. It certifies that a specific packaging type complies with the sustainability requirements outlined in Articles 5 through 12 of the PPWR.

One of the most critical aspects of this new rule is its granularity. The declaration is not issued at a company or brand level, but rather per packaging format. If a brand uses 50 different box designs, dimensions, or material combinations, it will need 50 distinct declarations, each backed by comprehensive technical documentation. These technical files must be retained for five years for single-use packaging and up to ten years for reusable formats.

Beyond Recyclability: Strict Limits on PFAS and Heavy Metals

While design for recycling remains a core pillar, the 2026 deadline brings immediate, stringent chemical restrictions that heavily impact food-contact packaging. The regulation sets strict limits on Per- and Polyfluoroalkyl Substances (PFAS), known as forever chemicals:

• A maximum of 25 parts per billion (ppb) for individual non-polymeric PFAS.
• A maximum of 250 ppb for the sum of non-polymeric PFAS.
• A strict limit of 50 parts per million (ppm) for total fluorine.

Additionally, the combined concentration of heavy metals (lead, cadmium, mercury, and hexavalent chromium) must not exceed 100 mg/kg. Market surveillance authorities will rigorously enforce these thresholds from day one.

Impact on the Paper, Corrugated Board, and Printing Industries

For the paper and corrugated board sectors, the PPWR presents both a massive opportunity and a significant technical challenge. As brands move away from single-use plastics, fiber-based packaging has seen a surge in demand throughout 2024 and 2025. However, proving compliance is complex.

Paper manufacturers and converters must heavily scrutinize barrier coatings, adhesives, and printing inks. The traditional use of fluorinated compounds to create grease-resistant paper for food packaging must be entirely phased out to meet the new PFAS limits. Furthermore, the printing industry must ensure that varnishes and inks do not compromise the recyclability of the paperboard or exceed heavy metal limits.

Although raw material suppliers (such as paper mills and ink manufacturers) are not directly responsible for issuing the DoC, they are legally obligated to provide the converter or brand owner with all the necessary technical specifications, testing results, and compliance certificates to build the technical file.

Strategic Roadmap for 2026

The transition period from 2024 to early 2026 has been defined by auditing and supply chain realignment. With less than months to go before the August 12 deadline, companies should immediately execute the following steps:

• Audit Portfolios: Identify every distinct packaging format currently placed on the EU market.
• Supply Chain Transparency: Establish secure, traceable data flows with material suppliers to gather chemical and recyclability data.
• Eliminate Non-Compliant Materials: Phase out any barrier coatings containing PFAS and transition to advanced aqueous or bio-based alternatives.
• Digital Documentation: Implement centralized software systems to manage version-controlled declarations, as market surveillance authorities can demand the technical file at any time.

The PPWR Declaration of Conformity ensures that greenwashing is replaced by verifiable data. For the paper and corrugated industry, mastering this technical documentation will become a major competitive advantage in the European market.
