Packaging
Stack Packer
A free-standing, continuous-motion system that bags thermoformed products straight off a vertical trim press, at 20 to 65 stacks per minute.

The Stack Packer provides high-speed packing with the controlled motion of a servo-driven rotary mechanism that positions, opens and closes the seal bars. C-fold film is sealed on both sides to create the bag and advance it for closing, with a special delivery system to the closing head. A Windows 10 embedded controller on the frame holds parameters and recipes.
It is U.S. manufactured and carries the same technical advances and reliability found in other Irwin Research products.
