Have you ever wondered how glue is made? At LD Davis, we produce a wide range of adhesives tailored to meet the needs of various industries. Each type has a unique manufacturing process, from eco-friendly, natural glues to cutting-edge synthetic adhesives. Let’s take an in-depth look at how some of our most popular adhesives are created.

Protein glue, or animal glue, is an adhesive typically made from animal gelatin protein. It is also sometimes called “cake glue” in reference to its appearance in 9-10lb blocks after production To ensure protein glue remains a non-toxic and sustainable product, other raw materials, like water, Epsom salts, corn sugar, and glycerin, are added to the gelatin.

Used most commonly in bookbinding, box making, and lamination applications, protein glue is often applied using a wheel, roller, or application pad. Due to its raw ingredients and the nature of how it is applied when protein glue runs too thick or too thin, it can create a frustrating and often messy issue on your production line. 

Troubleshooting why your glue might be running too thin or too thick is essential to efficiency and product quality. To do that, it’s important to understand protein glue viscosity.

Winter is here, and with it come frigid temperatures that can impact more than just your heating bill—it can also affect your glue. Whether you’re working with liquid water-based adhesives or gelatin glue, cold weather can significantly alter their performance and, in turn, your production efficiency.

Let’s explore how cold weather affects these types of adhesive, why proper handling is essential, and how to mitigate production issues during winter. For additional tips on how to apply glue and transport it during the colder months, check out Glue Application and Storage Tips for Winter.

I was diagnosed with cancer in July 2023, and I honestly did not know what to expect. It is one of those things you never think will happen to you—until it does. And when it does, everything changes. On the day I received my diagnosis of endometrial cancer, I was on my way to my son’s house.
