Abstract
A recyclable structure and methods of recycling are provided herein. A recyclable structure for use in packaging comprises a paper layer, and a polymeric film layer. An adhesive layer adhesively joins the paper layer and the polymeric layer. The adhesive layer comprises an acrylic or a urethane adhesive. The recyclable structure 85% by subjecting the structure to mechanical stresses and repulping. The adhesive layer has a greater affinity for the polymeric film layer than the paper layer. Upon repulping the adhesive layer is mostly separated from the fibers within the paper layer.
