Abstract
Cyclodextrin compositions including one or more radiation polymerizable monomers and a cyclodextrin inclusion complex, the cyclodextrin inclusion complex including a cyclodextrin compound and an olefinic inhibitor of an ethylene generation in produce, are coated onto packaging materials and cured. Treated containers and treated package inserts having the cured cyclodextrin compositions are useful in packaging of respiring plant materials.
Claims25
A curable composition comprising a mixture of:
- one or more radiation polymerizable monomers,
- a prepolymer, and
- a cyclodextrin inclusion complex comprising α-cyclodextrin and 1-methylcyclopropene.
A method of making a treated packaging material, the method comprising
- a. combining one or more radiation polymerizable monomers with a cyclodextrin inclusion complex comprising α-cyclodextrin and 1-methylcyclopropene to form a first polymerizable mixture;
- b. prepolymerizing the first polymerizable mixture to form a prepolymerized mixture, the prepolymerized mixture having a viscosity of 10 cP to 2000 cP;
- c. adding one or more additional monomers and optionally a crosslinker to the prepolymerized mixture to form a second polymerizable mixture;
- d. coating the second polymerizable mixture onto at least a portion of one surface of a packaging material;
- and
- e. exposing the coating to a source of radiation to form a treated packaging material.
