Clearwater Paper Launches Circa™ Recycled Paperboard in Collaboration with Greenpaper for U.S. Market

Clearwater Paper Corporation launched Circa™ paperboard, a new coated recycled board (CRB) line for folding carton & carrier applications in the U.S.
The product line was developed through a strategic collaboration between Clearwater Paper & Greenpaper, a global producer of 100% recycled fiber paperboard.
Circa paperboard consists of two variants: Circa Carton for folding cartons & Circa Carrier, a high-strength board for demanding environments.
The new offering is made from 100% recycled fiber & supports sustainability goals while maintaining strength, printability, durability, & wet-strength performance.
Greenpaper produces the board using a circular manufacturing model on a newly-reinvested state-of-the-art recycled paper machine in Monterrey, Mexico.
The partnership combines Clearwater Paper's market reach & service with Greenpaper's manufacturing capabilities to serve independent converters in the U.S.
Circa paperboard provides a cost-effective, sustainable alternative to premium solid bleached sulfate (SBS) products for everyday packaging applications.
Clearwater Paper is a premier independent supplier of paperboard packaging products headquartered in Spokane, Washington.
Greenpaper is a privately held company with over 80 years of experience & an annual production capacity exceeding 360,000 tons.
