ABSTRACT:
A hot melt adhesive composition can be made using a polyester derived from 2-propanoic acid (lactic acid). A thermoplastic resin grade polyester can be formulated into a functional adhesive using adhesive components. A lower molecular weight material can be used as a tackifying resin with a biodegradable/compostable resin in a formulated hot melt adhesive. The adhesive material can be made pressure sensitive and can be made entirely by a degradable by combining the polyester polymer with other biodegradable/compostable ingredients. The resulting adhesive composition that can be used in a variety of applications. The biodegradable/compostable adhesive material can be used as a substitute for non-biodegradable materials made from commercial polymers that resist attack by bacteria, fungi and other microbial populations. The hot melt adhesives can be used in (e.g.) packaging and the manufacture of disposable articles which are made from degradable materials. The entire disposable article can be made from adhesives and structural materials that are fully biodegradable/compostable.
