MICROPOROUS STRETCH-THINNED FILM/NONWOVEN LAMINATES AND LIMITED USE OR DISPOSABLE PRODUCT APPLICATIONS |
摘要 |
<p>Breathable laminates of a film and nonwoven with increased toughness and the ability to undergo strain without splitting for applications as components of personal care products and other uses. The film is formed using a carrier/letdown resin approach where the filled carrier resin is an ethylene polymer or copolymer having a density at least 0.003 g/cc higher than the letdown resin which is also an ethylene copolymer but has a density in the range of less than about 0.915 g/cc and a melt index less than about 6. The resin phases may be dry blended, formed into a film, stretched and bonded to a nonwoven support layer.</p> |
