Abstract

A non-reactive hot melt adhesive containing a copolymer being substantially composed of a reaction product of lactide (L) and caprolactone (C) in a molar ratio (L/C) of at least 1.5. The adhesive further includes a carbodiimide compound. The presence of a small but effective amount of carbodiimide causes a stabilizing effect on the sealing properties of the adhesive, especially if it is exposed to higher temperatures. A method manufactures the adhesive and a method seals a package with the adhesive.
