Making Corrugated Boxes Reusable

Using reusable plastic totes to get molded parts from one part of a manufacturing operation to another is expensive; Box Latch makes it possible to use and reuse inexpensive corrugated boxes.

Wisconsin Plastics Inc. does a big business in supplying spring-loaded trays that display various food products in the refrigerated section of a supermarket. Think packs of sliced cheese or luncheon meat, for example—you pull out the front one and the rest slide neatly forward.

The Green Bay, Wis., firm assembles its spring-loaded trays from seven parts. Until recently, the firm relied on reusable plastic totes to get one plastic part called a “wing” from the location in the plant where it is injection molded to an assembly station elsewhere in the plant where two wings become part of the seven-part assembly. When emptied, the crates were then palletized and returned to the place where the injection molding machines operate. But these crates are, as Plant Manager Carl Bartle points out, very expensive. So when a way of using inexpensive single-wall corrugated boxes came to his attention, he was only too happy to switch.
