    摘要: A gussetted plastic bag and liner, wherein the bag is maintained open by an attached elastic band. The elastic is placed on either side of at least one gusset fold(s) in an untensioned state, so as to bridge the gusset. When the bag top is folded over a container rim, the elastic is stretched on the outside of the container. This placement permits the bag to be folded flat while providing a means to keep the bag open during use. The elastic is useful as a closure after use.

    摘要: Fluid filtration articles, including composite nonwoven fibrous webs, and methods of making and using such articles as gas or liquid filtration elements. The articles include a population of coarse microfibers having a population median diameter of at least 1 micrometer (μm) formed as a first layer, and a population of fine fibers having a population median diameter less than 10 μm formed as a second layer adjoining the first layer. At least one of the fiber populations may be oriented. In one implementation, the coarse microfibers and fine fibers are polymeric, the coarse microfibers have a population median diameter of at least 10 μm, and the fine fibers have a population median diameter less than 10 μm. In another implementation, the population of fine fibers has a population median diameter less than 1 μm. Optionally, one or both of the first and second layers may include particulates.

    摘要: A filter media is disclosed comprising a carrier and a web collected on the carrier. The web comprises hydrophilic polymeric meltblown fibers and a plurality of sorbent particles enmeshed in the hydrophilic polymeric meltblown fibers. The carrier comprises a porous sheet and has a carrier basis weight. The web has a web basis weight. The hydrophilic polymeric melt-blown fibers comprise at least 3% of the web basis weight and the plurality of sorbent particles comprise at most 97% of the web basis weight.
