Abstract
Stronger thermoplastic elastomeric films having improved tensile strength and elastic properties are disclosed herein. The thermoplastic elastomeric films include a combination of polyolefin-based thermoplastic elastomers, styrenic block copolymers, and strength-enhancing agents. The films are suitably free of filler particles such as calcium carbonate.
Claims20
A personal care product comprising a thermoplastic elastomeric film comprising greater than 65% by weight of a polyolefin-based thermoplastic elastomer, a styrenic block copolymer, and from about 3% to about 8% by weight of a strength-enhancing agent.
A personal care product comprising a thermoplastic elastomeric film comprising greater than 65% by weight polyolefin-based thermoplastic elastomers, from about 15% by weight to about 30% by weight styrenic block copolymer, and from about 3% by weight to about 8% by weight strength-enhancing agent.
A method of strengthening a thermoplastic elastomeric film of a personal care product, the method comprising blending greater than 65% by weight of a polyolefin-based thermoplastic elastomer, a styrenic block copolymer, and from about 3% to about 8% by weight of an inorganic clay.
