This document covers the design of any rigid packaging with the main body of the packaging unit predominantly made of PS or XPS and the design of separate components predominantly made of rigid PS or XPS with respect to compatibility of the design with state-of-the-art collecting, sorting and recycling processes and useability of the recyclates in an application.
Packaging constituents and packaging components made of other materials than PS and XPS are also covered by this document as they need to be evaluated on compatibility with PS or XPS polymer recycling.
