Polymers other than those mentioned in Decision 129/97/EC have all been identified with the code “7”. In order to provide more accurate information on the composition of plastic packaging, and given the significant number of existing polymers identified by the single code “7”, we suggest accompanying the number “7” with the abbreviation of the polymer’s name as per technical standard UNI EN 1043-1, where available.
For example, polyamide packaging may be identified as: PA 7.
