I was not at the meeting but it sounds like you are describing the Bee-o-pac system (rectangular) or the Ross Rounds system (round). Dadant sells both.
The Bee-O-Pac system consists of eight bee-o-pac frames that fit into a standard 6 5/8" honey super. These frames are assembled from two nearly identical frame halves. One half has eight holes die cut on its sides while the other half has rounded buttons in matching locations. These are snapped together to make one complete frame. After the bees fill the sections they are removed from the hive, the individual filled sections are separated and the lid is installed and the completed package is labeled and market ready. Made of recyclable food grade PET plastic, reduce labor up to 75% from hand cut method.
