Meet Model 72

Worry-Free, Secure, and Efficient Mail Opening

Whether you receive hundreds or thousands of envelopes per day or substantially less, the Model 72 is there to streamline mail opening. By reducing mail opening time by up to 78%, the Model 72 helps you stay ahead of your incoming mail and increase the efficiency of your mailroom. 

Automatic Feeder

Model 72 is equipped with an automatic mixed-mail feeder. The feeder has a built-in jogger that moves contents away from the edge to be cut to minimize the risk of damage.


The Model 72 is equipped with OPEX’s unique milling cutting technology, which chips a small amount away from the envelope rather than using a standard blade to prevent damage to the envelope’s contents.

User-Interface & Performance Control Center

A simple user interface and LCD screen provide the user with system controls, envelope counts, printer controls, performance statistics, and diagnostics. Additional software options and the ability to connect the system to an external computer allow the user to connect to the network and view the status of multiple Model 72 systems.

Extract and Empty Envelope Verification Section

After opening the envelope, the Model 72 moves it down its path. Then, it uses two vacuum-powered suction cups to open the cut envelope at an angle for the operator to remove contents easily. After verifying the envelope is empty, the system automatically discards it.


Operators can use the system comfortably with easy access to the contents presented by the system, sort bins, the user interface, system controls, and discard bins. An optional lift system that allows for height adjustment and wheelchair accessibility.

“I can definitely tell you that it will end up paying for itself over the course of several elections. But nonetheless, with the election process, time is money. So if we can save time on the front end, it saves us money in the long run and that’s a true benefit.”
