Abstract (en)

[origin: WO9923187A1] An adhesive tie-layer comprising a biodegradable aliphatic-aromatic copolyesters is described. The aliphatic-aromatic copolyesters are useful for a biodegradable and/or a breathable film or extrusion coating. These materials can be used in co-extrusions for bonding polyester and cellulosic plastics to various substrates. Desirably, the substrate has a surface energy of less than about 50 dynes/cm.
