As a member of the American Chemistry Council, we have adopted Responsible Care® Guiding Principles and the Product Safety Code of Management Practices to guide our efforts in material sourcing, development and management of our product portfolio throughout the value chain and life cycle. Sustainable and ethical management of our products protects our employees, customers and communities in which we operate, while maintaining customer confidence in Avient’s materials.

Eco-conscious packaging compositions are preferred by customers, pushing convertors and brand owners to use sustainable materials—perhaps partially based on renewable or bio-derived sources—that also ensure food contact compliance.
