Abstract
The invention pertains to a non-reactive hot-melt adhesive comprising 10-90 wt. %, calculated on the weight of the adhesive, of amorphous thermoplastic resin which is compatible with polylactic acid, wherein the amorphous thermoplastic resin is a random copolymer of lactic acid and further reactive monomer, 10-90 wt. %, calculated on the weight of the adhesive, of a polylactic acid polymer unit (PLAU) selected from poly-L-lactic acid (PLLAU) and poly-D-lactic acid (PDLAU), the unit having a number average molecular weight of at least 0.75 kg/mol.
