Just like with most natural products, glues have an expiration date.  You'll notice, especially with your natural glues (protein/gelatin based) and liquid water-based glues, that after they have hit their expiration date they may become moldy and unusable.

What do you do if your glue is expired?

Potdevin gluing equipment has been around since 1896, so it's no wonder many of our printing and laminating customers use these machines (and have for many years). 

One question we get pretty often is: what is the best way to clean animal glue (hot glue) from the Potdevin glue tray?

You're running animal glue on your production line and all of a sudden, it doesn't seem to be working properly. Your wraps aren't sticking and the glue seems to be drying too quickly. What happened? 

LD Davis protein glues (animal glues) have been used for game board and puzzle manufacturing for nearly 80 years. To learn more about this unique industry and glue application, we sat down with Technical Sales Manager, Kelly Benjamin, to learn more.
