Opal And The Environment

We are a responsible manufacturer when it comes to the environment. Opal are proud to have been one of the first postal packaging manufacturers to be awarded with the FSC Accreditation.

The FSC certificate is the top award for environmental standards. It means we only purchase paper and board that originally comes from forests that are responsibly managed and support the local communities that work there. By choosing FSC products we can follow the supply chain back to the original forest.
