As consumers become heavily focused on the importance of biodegradablilty and eco-friendliness, manufacturers need to start thinking "green" in all facets of the manufacturing process.  Today’s consumers, especially the Millennials and younger Gen Z bunch, place high importance on sustainability (Packaging Strategies). They are scouring store shelves for products that are made and packaged sustainably. 

Sustainability, especially in packaging, is a hard subject to ignore. Check out how the packaging experts at L'Oreal are making the switch to sustainable packaging:



 As you focus on sourcing sustainable raw materials, don't forget the glue. Gelatin protein glues are biodegradable, recyclable and repulpable - the perfect match for green packaging. 

Geltain Protein-based Glues for Sustainable Packaging

L.D. Davis protein-based glues are completely hydropulpable 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.

All of the 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.

None of the raw materials are listed by OSHA, RCRA, NTP, SARA Title III or any other hazardous ingredient listing.
