ABSTRACT:
Multiple layer structures incorporating at least one polymeric film layer and at least one nonwoven fabric layer and products produced from such structures are provided. The polymeric film layer includes at least one tackifier resin. The at least one tackifier resin may be selected from a variety of resins including synthetic and natural resins. In certain embodiments, the at least one tackifier resin may be present at a concentration of about 0.1 wt. % to about 50 wt. % of the polymeric layer. The polymeric film layer may include one or more polymeric components selected from a variety of polymeric materials. Exemplary polymeric materials include polyethylene and ethylene vinyl acetate although as discussed hereinafter, a wide range of polymeric joined with a nonwoven fabric. The multiple layer structures may include additional layers made from a variety of materials. The structures exhibit beneficial peel strength properties between the polymeric layer and the nonwoven fabric layer.
