Abstract
The present invention provides a thermoplastic olefin composition that is particularly suitable for use in extruding tapes or films that can be further processed to form the hook portion of hook-and-loop fasteners for use on disposable absorbent products. The thermoplastic olefin compositions according to the invention provide the opacity, tear strength and flexural modulus considered optimal for such applications. Thermoplastic olefin compositions according to the invention include an olefin component including a highly crystalline homopolymer of polypropylene, an inorganic particulate filler component, and a colorant package including titanium dioxide and iron oxide pigments.
