  • Patent number: 8334343
    Abstract: Thermoplastic polymer compositions, films, continues, closures, laminates can comprise a modified vinyl polymer said modified polymer having a moiety comprising a cyclodextrin compound. The cyclodextrin compound, locked into the polymer structure, can absorb impurities, permeants, or other undesirable volatile materials. The cooperation between the cyclodextrin grafted onto the thermoplastic polymer and the polymer structure can provide barrier properties to a film, web or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film or Web preventing the permeant or contaminant from passing into the interior of a container or enclosure.

  • Patent number: 8152902
    Abstract: The invention relates to compositions that can be used to adsorb low concentration, preferably, for example less than 15 ppm, of unwanted or target substances. Typically the absorbance can be from an enclosed vapor phase. Such absorbency is accomplished in a contained substantially enclosed gaseous volume or atmosphere using a composition comprising a cyclodextrin compound and a polyethylenimine that can have an absorbency capability for low concentrations of unwanted or target substances. Such absorbency can be obtained with thermoplastic materials used in the form of bulk polymer or a film, fiber, web, woven fabric, nonwoven fabric, sheet, packaging and other such structures including or surrounding the enclosed volume. The adsorbent of the invention is typically used in the context of an enclosed volume, also known as an enclosed ambient vapor phase that contains the adsorbent of the invention and the unwanted or target substances at a concentration that is not desirable.

  • Patent number: 8148466
    Abstract: Thermoplastic polymer compositions, films, containers, laminates and fibers can comprise a modified polymer. The said modified polymer having a moiety comprising a half-ester reaction product of cyclodextrin and metal and/or organic group covalently bonded to some portion of the half-acid moieties. The cyclodextrin compound, grafted to the polymer structure, can scavenge impurities, permeants, or other undesirable volatile contaminants. The cooperation between the modified polymer's carboxylic acidic groups, basic groups and grafted cyclodextrin can provide active barrier properties to a film, web, fiber or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film, web or fiber preventing the permeant from passing into the interior of a container, or the contaminant can be scavenged from the enclosed headspace or surrounding environment.

  • Patent number: 8129450
    Abstract: Durable and disposable articles are provided which include a thermoplastic polymer composition, which includes a blend of a polymer and a modified polymer. The modified polymer has covalently bonded pendant substituents derived from cyclodextrin. The articles can be a films, coatings, nonwoven webs, or monolithic articles. An article can have the polymer composition as one part of the article, such as in one distinct area of the article, or on the surface of the article, for example as a coating or surface film. The article can be, for example, a multilayer barrier film, a nonwoven sheet or pad, an absorbent article, or a storage container.

  • Publication number: 20110143004
    Abstract: Thermoplastic polyolefin polymer compositions, polymer chips, fibers, woven or nonwoven fabrics, films, closures, and laminates include a polymer and cyclodextrin compound with a volatile maturation inhibitor or an olefinic ethylene receptor antagonist in respiring produce materials. The polymer composition can also include a cyclodextrin-modified polymer or a substituted cyclodextrin. Olefinic ethylene inhibitors can be formed in the cyclodextrin composition, wherein the cyclodextrin releases the olefinic inhibitor composition when used in produce packaging materials. Coating compositions can also be made. The inhibitor is introduced into the materials and is released under controlled conditions of humidity. Upon release, the olefinic inhibitor blocks ethylene receptor sites on proteins that control maturation and can produce an extended period during which the produce does not substantially complete maturation or ripening to a degree leading to spoilage.

  • Patent number: 7931957
    Abstract: Described are fiber materials having improved malodor scavenger properties and a process for the manufacture of said materials. In particular, described are fiber materials usable in the manufacture of disposable or washable diapers, incontinent products, sanitary napkins and other such hygiene and personal care articles with improved malodor scavenger properties, and to methods of manufacturing such materials. It has been found that the incorporation of, especially nanosized, metal particles and/or a cyclodextrin material into fibers creates a “reactive” material having excellent malodor scavenging properties. More specifically, it has been found that the presence of nanosized metal or metal alloy particles and/or a cyclodextrin material in a fiber material, preferably a synthetic polymer material and more preferably a synthetic thermoplastic polymer fiber material leads to fiber materials or nonwovens having odor-controlling properties.
