LD Davis has been making eco-friendly, non-toxic, re-pulpable, recyclable and biodegradable adhesives long before it was fashionable to be “green".
We use gelatin proteins (a non-consumable grade similar to those that go into food and pharmaceutical products like Jell-O and Gel-tabs), sugars (dry and syrup), Epsom salt, water and glycerin. It’s likely you’ve used these raw materials in your kitchen at home.
We also recycle millions of pounds of waste gelatin from nutritional and pharmaceutical manufacturers—all products designed to be easily dissolved and digested.
More About Gelatin
Gelatin is a protein derived from its parent protein, collagen. It is a hydrophilic colloid in an aqueous solution, nearly tasteless and odorless, vitreous and brittle as a solid and typically faint yellow in color.
Gelatin is graded according to its strength or bloom, with a higher bloom indicating a higher grade. Gelatin is an extremely important part of the manufacturing process for many LD Davis solutions. In the 1970's, we actively worked to replace the primary raw material in our animal glues with recycled pharmaceutical and nutritional gelatin in the form of soft gel netting and ground hard cap.
The gelatin we use today is inspected for quality as part of our 12-point quality control system for all incoming raw materials and outgoing finished products in our on-site Laboratory. During this quality control, we test for color, viscosity and odor before it goes into production.
Why is it important to use recycled gelatin material?
Pharmaceutical and nutritional companies produce a significant amount of excess gelatin that would normally be disposed in landfills. LD Davis takes pride in our effort to reduce waste and help the environment by recycling these materials for use in our glue products. In doing so, we gain a high-quality raw material source and these companies successfully eliminate a waste stream.
From this practice, LD Davis has quickly become the largest purchaser of recycled gelatin in the United States. We pride ourselves on manufacturing eco-friendly, non-toxic and recyclable glues and the use of recycled gelatin lets us continue to produce high-quality products that meet these standards.

Natural Eco-Friendly Adhesives for Sustainable Packaging
Gelatin-based natural glues, also called protein glues, are completely hydro-pulpable by nature of their composition. They are based on gelatin protein which is derived from the hydrolysis of collagen. Collagen is a protein ingredient of animal hide, tissue and bone.
Protein glue is composed of polyamides of alpha-amino acids. The solubility of protein-based glues in water is due in large part to the fact that five of the major constituent amino acids present in glue possess high water solubility. Protein glues are insoluble in oils, waxes, organic solvents and absolute alcohol. They may be emulsified in water-oil or oil-water systems.
The various other raw materials used to compound our glues are from the sugar, starch, polyol and salt families. All ingredients used to modify the adhesives are water soluble and in most cases are non-edible grades intended for industrial use. We also utilize edible-grade raw materials, e.g. corn syrup (glucose), sodium chloride (table salt), glycerin USP grade, etc. when required.
