## Abstract

A starch-based adhesive composition, having a tan δ at 10 Hz and 20° C. of at least 1.40 is provided. The adhesive composition is in particular useful as labelling adhesive. Also provided is a bottle that has a label whereby the label is attached to the bottle by the aforesaid adhesive composition.
