One machine. Multiple solutions.

Streamline your operations and get to market quicker with Meta® Duo, WestRock’s newest automation technology. Offering true multi-channel, in-house automation, Meta Duo efficiently transitions between 4-sided, 8-sided, half-slotted containers (HSCs), one- and two-piece shelf-ready packaging (SRP) designs and ships-in-own-container (SIOC) units, helping you meet various retailer and e-tailer requirements from a single, small footprint machine.

Meta Duo utilizes our unique Meta® Systems precision forming technology. Cases are formed around a fixed mandrel, minimizing case skew and maximizing structural integrity, resulting in cases that outperform comparable standard regular slotted containers (RSCs) in production efficiency (higher run speeds) and stacking strength.
