Abstract
A method and composition of packaging an adhesive composition, especially a thermoplastic or thermosetting hot melt adhesive. The method comprises the steps of providing one substantially uniform separate portion of the adhesive composition; sufficiently solidifying said portion for packaging; and substantially completely surrounding said sufficiently solidified portion with a biodegradable polymeric packaging material. The packaging material being meltable together with the adhesive composition and blendable into said molten adhesive composition, the kind and amount of said biodegradable packaging material being chosen so as not to disadvantageously affect the properties of the adhesive composition when blended into the molten adhesive and applied to a substrate.
