How can we assure that consumers understand that it is the packaging that is labelled with the Svanen ecolabel and not the content?

We have a specific Svanen logo that clearly states that it is the packaging that is ecolabelled with Svanen and not the content. We have rules that do not allow this specific Svanen logo to be placed on the front of the packaging. The label also comes with an explanatory text which clarifies this for the consumer.
