ABSTRACT:
There is provided herein a multilayer laminate comprised of a layer of a film and a layer of a nonwoven fabric. The film is made from polymers and has as one surface a semi-crystalline/amorphous or "heterophasic" polymer, an optional inner, less expensive, filler type polymer, and as the other surface, a polymer with a lower coefficient of friction. The nonwoven fabric may be a spunbond or meltblown fabric, preferably spunbond and preferably also including a heterophasic polymer. The film and nonwoven components are bonded together using thermal point bonding preferably while the film is stretched at least 5 percent. Such a laminate may be made into a personal care product like a diaper, training pant, absorbent underpants, adult incontinence product, and feminine hygiene product.
