Efficient, Flexible Semi-Automatic Carton Sealing
Part of the EconoCore line, the Econocorp Twinseal is an economical, semi-automatic carton sealer designed to glue and seal two outer flaps of a corrugate or paperboard carton simultaneously.

Whether you’re sealing cartons in cannabis, food, industrial, or craft beverage markets, the Twinseal delivers dependable performance with simplicity and speed.

Compact Footprint, Space-Saving Design with Fast, Flexible Changeovers
Designed for entry-level automation and low-to-moderate production lines, the Econocorp Twinseal delivers dependable performance with speeds of up to 30 cartons per minute. It’s an ideal solution for small-to-medium operations looking to increase packaging efficiency, reduce manual labor, and streamline sealing processes without investing in large, complex systems.
With its compact footprint, the Twinseal fits easily into tight or space-constrained environments, making it perfect for facilities with limited floor space or those looking to add automation without reconfiguring their current layout. It’s also designed for seamless integration into current production lines, helping minimize set up time and avoid disruptions to ongoing production.
One of the standout features of the Twinseal is its hand crank for lateral adjustments, which allows for fast and easy changeovers. Combined with minimal change parts, switching between different carton sizes takes just minutes, minimizing downtime and maximizing productivity. This level of flexibility makes Twinseal ideal for multi-SKU operations, varying carton sizes, short product runs, or seasonal product lines where quick adjustments are essential.
