PPWR Compliance Information

We can provide available product specifications and supporting information to help customers complete their compliance assessments. However, paper construction or potential recyclability alone does not confirm full PPWR compliance.

The responsible economic operator must assess the finished packaging and its intended use against all applicable requirements, including packaging minimisation, substances of concern, recyclability, labelling and technical documentation.

Customers intending to place these products on the EU market should email sales@expresspackaging.co.uk to request the latest available documentation and confirm suitability for their application before making a PPWR compliance claim.
