Abstract

A specific mixture of polyols, at least one of which contains the transesterification product of the polymer polylactic acid with natural oils. The mixture of polyols can be used as one component of a two-component adhesive for laminating flexible packaging. The other component comprises an isocyanate-functionalized compound. The two components are combined before use and the resulting adhesive can be used to bond films to form a flexible packaging material.
