Abstract
An exemplary embodiment of the present invention provides starch-based hot melt adhesive comprised of a composition including starch, a thermoplastic polymer, a tackifier, a plasticizer, and an adhesion promoter. The hot melt adhesive according to the exemplary embodiment of the present invention contains about 25 to 55 weight % of the starch which is infinitely renewable biomass, and, thus, it is less harmful and more eco-friendly and has a reduced manufacturing costs and is less sensitive to exhaustion of petroleum-based resources, as compared with the conventional hot melt adhesive mainly containing a petroleum-based material. Further, the hot melt adhesive according to the exemplary embodiment of the present invention imparts excellent adhesion strength and workability at the time of adhesion between different kinds of adherends such as a hydrophobic adherend and a hydrophilic adherend and can be applied to various fields such as packaging, bookbinding, construction, woodworking, and textile fields.
