What does the flustix trustmark on a package mean?

A flustix trustmark means that a particular property of that product has been independently tested and confirmed under a defined certification programme. Which property that is appears on the trustmark itself: LESS PLASTICS with the assessed figure as MIN. X % PLASTIC-FREE, PRODUCT CONTENT MICROPLASTIC-FREE, RECYCLED with the recycled share in per cent, RECYCLABLE for the recyclability of packaging, or PFAS-FREE.

Every trustmark carries a licence number that lets you verify the certificate in the public database. A trustmark is not a general sustainability statement about the company, but evidence for exactly the property named on it.
