Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

This document was prepared by Technical Committee ISO/TC 122, Packaging, Subcommittee SC 4, Packaging and the environment.

Introduction

The purpose of this document is to specify a number of markings used to identify packaging materials, with the aim to support the efficient collection, sorting, recycling and recovery after use. The collection and sorting of used packaging is a prerequisite for a successful recycling and recovery process.

Although several countries and regions have established marking systems for material identification, the absence of such systems in other countries and regions has created difficulties for individuals and organizations to properly identify packaging materials. Waste operators lacking sufficient means of mechanical sorting face problems in properly separating the used packaging materials, when specified identification markings are lacking. Moreover, packaging material markings are not always linked to collection symbols for packaging, which depend on the relevant packaging waste management systems.

The usefulness of markings for packaging materials is limited in countries and regions with established collection and sorting schemes, where the latest technologies are used to separate the packaging materials fractions.

This document contains a number of identification markings with their sorting and recycling systems which are successfully used in some countries and regions.

1 Scope

This document shows some examples of markings (words, numbers or symbols) for the identification of packaging materials. This document is applicable to all types of packaging in order to enable the identification of the materials used.
