<p><P>PROBLEM TO BE SOLVED: To provide an innovative functional material eliminating anxiety about safety of food on migration of cyclodextrin, reducing material cost, coexisting in-plant scrap recycle and recycling after supplying to market without any discrepancies. <P>SOLUTION: Thermoplastic polymer compositions, films, containers, closures, laminates can comprise a modified vinyl polymer having a moiety comprising a cyclodextrin compound. The cyclodextrin compound, fixed 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 packaging. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
