With the rapid rise of warehouse automation continuing to accelerate, distribution facilities face operational challenges ranging from the utilization of limited space to continuous system performance improvement. Containers are now a critical element of modern warehouse infrastructure.
Monoflo International recently announced the introduction of two new containers engineered to bring efficiency and durability to automated warehouse operations everyone: the Foldable Stack Only (FSO) container and Dual Base stack-only (SO) container. The new designs are scheduled for Q2 production and are already being specified on select projects.
“Automated storage and retrieval systems are evolving so fast,” says Dennis Williams, Monoflo’s Automation Group Director. “When it comes to packaging, we don’t want to just keep up. We’re setting the pace of innovation.”
Foldable Stack Only

The Foldable Stack Only (FSO) is a collapsible container engineered to meet the demands of automated systems. Traditional collapsible containers have long offered logistical space-saving advantages but were often too weak, bulky, or unreliable to perform efficiently in high-throughput automation environments.
The Monoflo FSO line delivers the strength and reliability of traditional stack-only containers while unlocking space and freight savings. With a 4:1 storage ratio, the FSO offers up to a 75% freight reduction and requires a smaller storage footprint for space-constrained facilities.
Dual Base Stack-Only

Monoflo also introduced its new Dual Base stack-only container, a one-piece injection-molded design engineered for automation-driven warehouse environments. The Dual Base design balances welded-base strength with manufacturing efficiency.
Building on spider-base container designs widely used in European logistics systems, the container features smooth interior and exterior surfaces ideal for fresh food and sanitation-sensitive automation applications. The textured conveyance bottom and angled rib geometry are engineered to improve conveyance and reduce system noise in high-throughput operations.
Monoflo has decades of leadership in reusable transport packaging, including collapsible containers, automation-ready trays, and engineered solutions for high-velocity environments.
