  • Patent number: 6190758
    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.

  • Patent number: 6156421
    Abstract: A breathable microporous film is prepared by extruding a film comprising about 30 to 70% by weight of a thermoplastic polymer, about 30 to 70% by weight of filler particles having an average particle size less than about 10 microns and about 100 to 1000 PPM of a mono-functional hindered phenol, such as .alpha.-tocopherol, and then sufficiently stretching the filled film in at least one direction thereby creating a fine pore network therein and a water vapor transmission rate in excess of 300 g/m.sup.2 /24 hours.
