Abstract
Described herein is an actinically curable adhesive composition, suitable for sealing flexible packaging, that includes an inert urethane polymer and an ethylenically unsaturated monomer component selected from at least one monofunctional ethylenically unsaturated monomer, at least one multifunctional ethylenically unsaturated monomer, and a combination thereof, wherein the ethylenically unsaturated monomer component disperses the inert urethane polymer. The compositions are suitable for forming flexible packaging materials for foods and other materials, particularly sensitive materials. Also described are flexible packaging materials and a method for preparing an actinically curable adhesive composition.
