Packaging - Design for recycling of plastic packaging - Part 1: Definitions and principles for design-for-recycling of plastic packaging

This document provides a framework and principles for design for recycling documents for assessing the identification of the level of compatibility of plastic-packaging feature with the applicable collection, sorting and recycling processes, describing the level of compatibility.
This document covers any packaging predominantly made of plastic and separate components predominantly made of plastic. It aims to provide a consistent approach for the guidelines and protocols for each polymer and format.

Design for recycling guidelines are a common way of describing compatibility with plastic packaging
collection, sorting and recycling into high quality recycled plastic into state-of-the-art facilities. They
provide guidance on the level compatibility, defined as:
— green: Packaging constituents with full compatibility with recycling;
— yellow: Packaging constituents with limited compatibility with recycling;
— red: Packaging constituents which are not compatible with recycling.
Recyclability guidelines will require regular review and improvement to reflect innovations in design,
collection, sorting and recycling.
The Design for Recycling Guidelines provided in this series of standards are representative of the state of
the art in Europe and cover all steps from design for recycling, packaging waste collection, sorting,
recycling into recycled plastic and to use in a new application.
oSIST prEN 18120-1:2024
prEN 18120-1:2024 (E)
Packaging recyclability is the combination of five parameters: packaging designed for recycling,
packaging waste collection, sorting when necessary, recycling and use of recycled plastic in a new
application. This series of standards covers one parameter: the design for recycling.

1 Scope
This document provides a process that manages the identification of the level of compatibility of plastic
packaging features with collection, sorting and recycling, describing the level of compatibility as fully,
limited, and not recyclable.
This standard covers any plastic packaging where the main body is made of plastic material. It targets to
harmonize the design for recycling standard approach for each resin.

criteria: proven and commercially available, technology at TRL9, delivering sufficient results in terms of
yield and quality, already in use in the European market, affordable to relevant economic operators in

oSIST prEN 18120-1:2024
prEN 18120-1:2024 (E)
Note 1 to entry: Flexible packaging structures can be single or multi-layered using a variety of materials including
plastic film, paper, aluminium foil or any combination of these. The construction may be plain, printed, coated
and/or laminated.
Note 2 to entry: Flexible packaging structures are generally used to package and protect consumer and other
products. These can include Fast Moving Consumer Goods (FMCG) products such as confectionery, snack foods,
frozen foods, produce, bakery, meat, dairy, pet foods, processed food, cosmetics, personal care, household
detergents, beverage bottle/can wrapping, pharmaceuticals, medical and other technical products such as utensils

3.18
semi-rigid/semi-flexible packaging
all packaging that cannot be clearly categorised by type as either rigid or flexible packaging, such as two-
piece packaging with a thick but flexible bottom film or pouches with dimensionally stable closure
systems. (Supplement: As this packaging behaves diffusely in the separation processes used to separate
the flexibles (air classifying and ballistic separation), it is recommended that the requirements for
flexibles and rigids are both applied to such packaging when assessing recyclability)
3.19

such as enhanced thermal stability, easier processing, slip, antiblock properties, UV protection or simply change in
density. Additives can be added during manufacturing of the polymer (typically antioxidants, polymer processing
aids, antiblock and/or slip) and during downstream converting. Some additives added during further processing
steps have a profound effect on the density of the material such as inorganic fillers or foaming agents.
Note 3 to entry: Foaming (both chemical and physical) can decrease the density of a PE component compared to
the intrinsic density value of the polymer itself.
