On April 15, 2026, the European Committee for Standardization (CEN) released the highly anticipated EN 18120 standard, a comprehensive suite of 14 distinct parts dedicated to the Design for Recycling (DfR) of plastic packaging. Also discussed in our recent guide on Design for Recycling for Flexible Packaging, these technical principles are now a coordinated technical ecosystem that addresses every major resin and format, from PET bottles to flexible PE films.
TABLE OF CONTENTS
A Structured and Comprehensive Framework
The release of the EN 18120 standard represents a monumental shift in how packaging is assessed. By breaking the standard down into specific parts, CEN has provided targeted guidance for different material streams, eliminating the “one-size-fits-all” ambiguity of the past. While Part 1 establishes the overarching definitions and principles, the subsequent parts provide all the necessary details for industrial R&D.
The series covers the diversity of the market:
- Definitions & Sorting: Part 1 (Definitions) and Part 3 (Sortability evaluation).
- Flexible Packaging: Part 7 (Guidelines) and Part 13 (Protocols) for PE and PP.
- Rigid PET: Parts 4, 5, 10 and 11, covering both bottles and non-bottle rigid formats.
- Rigid PE, PP and PS: Parts 6, 8, 12 and 14 for rigid containers and polystyrene.
- Expanded Synthetics: Parts 9 and 15 for EPS packaging (Expanded Polystyrene).
Navigating Guidelines versus Evaluation Protocols
One of the most innovative aspects of this standard is the distinction between Design Guidelines and Evaluation Protocols. The Guidelines (such as Part 6 for rigid PE/PP or Part 7 for flexibles) act as a proactive roadmap for the initial design phase, helping engineers make informed material and component choices. In contrast, the Protocols (such as Part 12 for rigid recycling or Part 15 for EPS) establish the formal testing methodologies required to verify those designs.
This structure allows companies to not only design with the environment in mind but to verify their results through standardized testing methodologies. It provides a framework that is essential for legal Declarations of Compliance and for justifying recyclability claims under the increasingly strict EU consumer protection laws.
The PPWR Roadmap and the 6-Month Implementation Warning
The timing of this release is strategic, as the EN 18120 series is intended to be the primary technical reference for the implementation of the PPWR. While the regulation sets the legal mandate for all packaging to be recyclable by 2030, these CEN standards provide the actual assessment methods used to determine “Recyclability Performance Grades.”
However, there is an immediate timeline that businesses must note: CEN National Standardization Bodies have a mandatory 6-month window to implement these European Standards from their publishing date. By October 2026, national standardizing bodies (such as ELOT, DIN or AFNOR) must adopt these as national standards and withdraw any conflicting national guidelines. This means that the transition to a harmonized European design language is an immediate requirement for market access.
Complementarity with CEFLEX and Industry Initiatives
The publication of these standards has been met with significant support from industry platforms like the Circular Economy for Flexible Packaging. CEFLEX actively participated in the development of the series, specifically leading projects for flexible packaging (Parts 7 and 13).
Sorting and the Technical Evaluation Process
Beyond material selection, the EN 18120 series places a heavy emphasis on the physical reality of the waste stream. Part 3, specifically dedicated to sortability, acknowledges that a package is only recyclable if it can be successfully identified by Near-Infrared (NIR) sensors. This addresses the hidden disruptors, such as certain carbon black pigments, incompatible adhesives or problematic coatings that have historically caused high rejection rates.
By standardizing the evaluation process for both sortability and mechanical reprocessing, CEN is forcing a shift toward packaging that is operationally circular rather than just theoretically recyclable.
Conclusion
The launch of the EN 18120 standard on April 15th, 2026 marks the transition to the formal enforcement of design-for-recycling principles across the EU. With 15 parts now available to cover the diversity of the plastic packaging market, professionals across the value chain, from designers and converters to regulatory experts, have a robust and data-driven roadmap. These standards provide the clarity needed to manage Extended Producer Responsibility (EPR) costs, substantiate environmental claims and ensure long-term compliance with the PPWR.
In the new circular economy, the EN 18120 series is the definitive guide for bridging the gap between scientific expertise and the increasingly rigorous legal requirements of the European market. The roadmap to 2030 is no longer a matter of opinion; it is a matter of standard.
