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.

Abstract: Described is a closure element for a container. The closure elements has a sealing element which contains a thermoplastic polymer, and an effective absorbing amount of an unmodified cyclodextrin material. The unmodified cyclodextrin material may be an ?-cyclodextrin, ?-cyclodextrin, ?-cyclodextrin, and mixtures thereof. The sealing element can act as a barrier with respect to permeants, such as aromatic substances, trichloroanisole, aldehydes or ketones and/or impurities from the polymer.

Abstract: Described is a closure for a container. The closure element has a sealing element which contains a thermoplastic polymer; an effective absorbing amount of a cyclodextrin material; and at least one amide lubricant. The cyclodextrin material may be ?-cyclodextrin, ?-cyclodextrin, ?-cyclodextrin, derivatives of ?-cyclodextrin, derivatives of ?-cyclodextrin and derivatives of ?-cyclodextrin and mixtures thereof. The sealing element forms an effective barrier against volatile migrant contaminants, such as aromatic substances, trichloroanisole, aldehydes or ketones, and reduces the contamination with oxidative decomposition products resulting from the lubricant.

Abstract: Described is a packaging material which contains a matrix material coated with a thermoplastic polymer and an effective absorbing amount of a cyclodextrin material. The cyclodextrin material is selected from the group consisting of an ?-cyclodextrin, a ?-cyclodextrin, a ?-cyclodextrin or mixtures thereof. The packing material can act as a barrier with respect to permeants, such as water vapor, aromatic and aliphatic hydrocarbons, monomer compositions and residues, off odors, off flavors, perfumes, smoke, pesticides, toxic materials, etc. The barrier properties of the cyclodextrin material may be altered by modifying the moisture content of the cyclodextrin material prior to incorporating into the matrix material.

Abstract: Described is a closure element including a sealing element or polymer liner compound having improved barrier properties. The sealing element or compound includes (a) a thermoplastic polymer; and (b) an effective absorbing amount of a cyclodextrin material. The cyclodextrin material is selected from the group comprising &agr;-cyclodextrin, &bgr;-cyclodextrin, &ggr;-cyclodextrin, derivatives of &agr;-cyclodextrin, &bgr;-cyclodextrin and &ggr;-cyclodextrin and mixtures thereof.

Abstract: Described is a packaging material having improved barrier properties, the material comprising a matrix material and uniformly dispersed in the matrix material, an effective absorbing amount of a cyclodextrin material, wherein the cyclodextrin comprises an &agr;-cyclodextrin, a &bgr;-cyclodextrin, a &ggr;-cyclodextrin or mixtures thereof, having pendant moieties or substituents that render the cyclodextrin compatible with the matrix material. It is believed that it may be possible to regulate or optimize the barrier and trapping properties of a cyclodextrin-containing material by varying the moisture content in the cyclodextrin prior to incorporation into the matrix material.
