Marking of packaging

For packaging of plastic and composite materials classification codes and marking rules have been introduced to show what plastic type or composite material has been used to make the packaging. The marking is intended to facilitate sorting when packagings are collected as waste in view of being recycled.

Not a requirement

Packaging placed on the market in Denmark may be marked to show the type of packaging material. In other EU-countries the marking of packaging are legally required.
