Water-modifiable flushable polyolefin containing film and article made therefrom

摘要

The invention provides a water-degradable polyolefin-containing film having greater than about 55 weight percent of a polyolefin and less than about 45 weight percent of poly(ethylene oxide) of weight average molecular weight of less than about 100,000. Preferably, the polyolefin is low density polyethylene. The polyolefin-containing film, when immersed in water for about 30 seconds, loses at least 10% in two or more of the tensile properties: percent strain-to-break, peak stress, energy-to-break and modulus when compared to the dry or pre-immersion values. Also provided are flushable personal care articles such as infant diapers, feminine hygiene napkins, and adult incontinence garments having a backing or barrier layer comprising a water degradable polyolefin-containing film of the invention.
