| 摘要 |
<p>The present invention relates to 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 a-cyclodextrin, a ß-cyclodextrin, a gamma-cyclodextrin or mixtures thereof, having pendant moieties or substituents that render the cyclodextrin compatible with the matrix material. It has been found that it is 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.</p> |
