Abstract: Disclosed are packing material/matrix and methods of making thereof for slow or extended release of at least one active volatile compound(s). Provided are gel matrix polymerized from particular pre-polymer, and optionally initiators are added during polymerization. The active volatile compounds are encapsulated in molecular encapsulating agents into a form of molecular complex, an the molecular complex is further incorporated into the gel matrix. Also provided are methods for preparing the gel matrix and using thereof.

Abstract: The present invention relates to packaging material/matrix and methods of making such packaging material/matrix for slow or extended release of at least one active volatile compound(s). Provided are methods and compositions for a polymer matrix incorporating at least one active volatile compound (for example 1-methylcyclopropene or 1-MCP) and the polymer matrix is synthesized by polycondensation. This polymer matrix can slowly release the active volatile compound after contacting with a solvent (for example moisture). Also provided is the use of such polymer matrix to prolong the shelf-life of fruits and vegetables.
