What are dyne pens? What is a dyne test? Why is this test important?

We get questions like these often, and to better explain this testing method we went right to the source.

Have you ever heard the old saying "Take the horse to the glue factory"? 

If you're here, you've probably heard that saying and wondered what horses have to do with glue. Here's where that quote originates from, as well as more about what raw materials are really used to manufacture glues. 

It's no secret that at LD Davis, we are a little obsessed with sustainable packaging glues.

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.
