Gluing — Sticking With Direct Mail

There are primarily two ways of applying remoist glue. The older technology—cold application of water-soluble remoist glue—works by transferring glue to paper by either a wheel or a blanket. This process has two main advantages.

First, heat by itself doesn't activate it, which means it's downstream laser compatible. Second, glue application "pads" can be different sizes and run in different directions, which allows the efficient manufacturing of products such as three-sided "U" bar reply devices and stamps.
