Tri-Wall Limited, a consolidated subsidiary of Rengo Co., has commenced operations at its newly established plant in Shandong Province, China. The facility, operated by Fengyuan Tri-Wall Packaging (Shandong) Co., was formed in 2024 as a joint venture with state-owned enterprise Shandong Fengyuan Group. The plant manufactures heavy duty and general corrugated board and cases, according to Rengo.

The location marks the first manufacturing site in Shandong Province to operate a corrugator capable of producing heavy duty corrugated board. Through the partnership, the venture secures a stable supply of containerboard and electricity from Shandong Fengyuan Group.

Rengo expects the strategic position to strengthen its market presence and accelerate development in the major economic region.
