Linerboard & Corrugating Medium

It’s often what’s inside that counts: trust your containers and displays to our high-quality linerboard and corrugating medium, uniquely engineered for strength and flexibility.

We serve a variety of customers, but our dedication to providing an outstanding customer experience and our low integration levels, which keep us nimble and flexible, make us particularly ideal for independent corrugators.

Sonoco is committed to responsible use of natural resources through responsible sourcing, recycling and use of recycled fiber in our paper-based packaging.  Sonoco’s U.S., Canadian, U.K., Brazilian and one of our Mexican mills are certified to one or more fiber certification programs.  These are:  the Forest Stewardship Council® (FSC®), Sustainable Forestry Initiative® (SFI®) and the Program for the Endorsement of Forest Certification® (PEFC®) Chain of Custody and Due Diligence System Standards.  Additionally, we have plants in our paper container packaging, industrial tubes & cores, and primary packaging carton operations that are certified to these programs and can produce certified packaging.  Overall sales (certified and not) by these mills and fiber certified plants is equal to 15% of Sonoco’s revenue.

All but three of our 19 global paperboard mills use 100% recycled fiber in their production.  Some amount of responsibly-sourced virgin fiber is needed for select grades of paperboard.  The amount of recycled fiber in our paper containers range from 60 to 80+ percent, depending on the product specifications for the package.  On average, the amount of recycled fiber used in our industrial tubes and cores exceeds 95 percent.
