Cyclodextrin compositions, articles, and methods
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.
1. A container comprising a treated packaging material, wherein the container comprises an enclosed volume, the treated packaging material comprising a cured cyclodextrin composition disposed on at least a portion of a surface of a packaging material, the cured cyclodextrin composition comprising a polymer derived from one or more radiation polymerizable monomers, one or more photoinitiators, and a cyclodextrin inclusion complex, the cyclodextrin inclusion complex comprising 1-methylcyclopropene; wherein the cured cyclodextrin composition is formed by the process of:
a. disposing a cyclodextrin composition comprising one or more radiation polymerizable monomers, about 0.1 wt % to 5 wt % of one or more photoinitiators based on the weight of the cyclodextrin composition, and about 0.5 wt % to 10 wt % of the cyclodextrin inclusion complex based on the weight of the cyclodextrin composition onto at least a portion of one surface of a packaging material at a thickness of about 0.01 micron to 1 millimeter to form a coating; and
b. exposing the coating to a source of radiation to form a cured cyclodextrin composition.
2. The container of claim 1 , wherein the source of radiation is ultraviolet radiation.
3. The container of claim 1 , wherein the cyclodextrin composition is exposed to ultraviolet radiation prior to the disposing.
