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 (e.g. 1-methylcyclopropene), 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, whereby the packaging materials have an enclosed volume and may have a means for controlling the amount of water in the enclosed volume, or a modified atmosphere with control of the permeability to oxygen and carbon dioxide, etc.
