Product Features
Robotic L-Bar Precision
The servo-driven L-bar mechanism gently guides products into cases without crushing or misalignment-critical for delicate items like bottles, electronics, and food trays. The robotic motion also ensures consistent case squareness, which improves sealing quality and stackability.
Hot Melt Glue-Superior to Tape
Hot melt adhesive creates a permanent, tamper-evident bond that resists moisture, heat, and rough handling during shipping. Unlike tape:
No peeling or adhesive failure
No tape waste or disposal cost
Clean, professional appearance-no visible tape strips
Quick Changeover for Production Flexibility
Stores up to 99 case size recipes on the touch screen. Changeover between sizes takes under 5 minutes with tool-less adjustments-perfect for co-packers and e-commerce operations with frequent SKU changes.
One Machine-Three Operations-One Operator
Unlike traditional lines that require separate erectors, packers, and sealers-each needing its own operator-our L-bar robotic system integrates all three functions:
Erects flat blanks into open cases
Packs products via robotic L-bar motion
Seals with hot melt glue for permanent closure
Result: 40% less floor space, 60% fewer operators, and dramatically lower capital cost.
