A barrier material comprising a thermoplastic and a compatible cyclodextrin derivative

A protective layer, comprising a model the polymer the utility model to the sheet and a comprises one or more of has a cyclodextrin is The Aromatic substituent group and cyclodextrin composition. The thermoplastic/cyclodextrin film substitution of the interaction of cyclodextrin and transudate a film to substantially block performance. The group consisting of cyclodextrin molecule wherein the cyclodextrin member is a dispersion of the film material, and stable, and wherein the thermoplastic according to any one of extrude. The material can be used as the monolayer film material and multi-layer film material, wherein the film is replaced by a process selected from the coating, and can be used the structural material, the thermoplastic with a production structure with thickness. The cyclodextrin and applied function of polymer to provide a heat-cured oxide for sheet, including, the transudate the compound or catches of the cyclodextrin compound and retains in membrane, the prevention transudate to electrodeionization of the film to control the film which the content, or the same. The transudate comprises a wherein the water material, to water, fat hydrocarbon or aromatic hydrocarbon, monomer, and interesting which compound and so on.
