LD Davis is one piece of the puzzle in jigsaw puzzle manufacturing; you guessed it, that piece is our adhesive. 

We’re often asked about the shelf life of our glue, as natural adhesives have an expiration date.  

Gelatin glue can last a year, but that depends on proper storage. In fact, storage plays a significant role in your adhesive and your entire production performance. 

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?
