This article reviews the state-of-the-art regarding the formulation and development of biobased hot melt adhesives. It also analyzes the several driving forces for such development and the barriers that are likely to inhibit quick and large scale commercialization. There seems to be a staggering amount of development activity related to biobased polymers, but they have not, as yet, made a significant commercial impact in the adhesive market. One reason for this is the lower volume of polymers used in adhesives when compared to the plastics used in the packaging, building, and consumer products sectors. Even so, the adhesive industry is taking reasonable, controlled steps to develop adhesive systems based on renewable sources, and nowhere is this more apparent than in the hot melt area. Hot melt adhesives are on the front lines for several reasons. One factor is the wide variety of large commercial applications especially in the environmentally sensitive areas of packaging.
