Plastic matters

Plastic should have more than one life

We are innovating to give plastics a second life. Today, three out of four of our products are made with Next Life Plastics. And of course, no compromise on quality.

Packaging matters

It's not just what's in the box

We prioritize using less plastic in our packaging, and more paper sourced from FSC™-certified forests and other controlled sources. This helps support responsible management of the world's forest.
