a hot melt adhesive composition can be made using a polyester derived from 2 - propanoic 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 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 .
