About the Automatic Four-Corner Carton Sealing Machine YJ-900A
The yj-900a uses servo-driven side guides to track carton width and height automatically, so mixed sizes can pass in random order with zero changeover time. That is what third-party logistics and multi-SKU warehouses need — the operator never stops to adjust the machine.
Side-drive belts keep the carton square during sealing, and an inline scanner can log every dimension straight to your WMS.
