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.

A method of activating a surface of a plastics substrate formed from: (a) polyaryletherketone such as polyether ether ketone (PEEK) polyether ketone ketone (PEKK), polyether ketone (PEK); polyether ether ketone ketone (PEEKK); or polyether ketone ether ketone ketone (PEKEKK); (b) a polymer containing a phenyl group directly attached to a carbonyl group, optionally wherein the carbonyl group is part of an amide group, such as polyarylamide (PARA); (c) polyphenylene sulfide (PPS); or (d) polyetherimide (PEI); for subsequent bonding,
the method comprising the step of exposing the surface to actinic radiation wherein the actinic radiation: includes radiation with wavelength in the range from about 10 nm to about 1000 nm; the energy of the actinic radiation to which the surface is exposed is in the range from about 0.5 J/cm.sup.2 to about 300 J/cm.sup.2. Hard to bond substrates are then more easily subsequently bonded for example using acrylic, epoxy or anaerobic adhesive.

Disclosed is a method of preparing polymer film-metal composites and uses of such composites. The metal can be in the form of a nanoparticle or a film. The methods comprise depositing on a surface, a composition comprising: a cationic metal precursor; a polymer film precursor that comprises a plurality of photopolymerizable groups; and a photoreducer-photoinitiator; then irradiating the composition under conditions to simultaneously reduce the cationic metal and polymerize the photopolymerizable groups to obtain the composite on the surface.

A composite film may include a first transparent substrate and a first anti-reflective coating overlying a first surface of the first transparent substrate. The first anti-reflective coating may include a first UV curable acrylate binder, a photo initiator component, and silica nanoparticles dispersed within the first anti-reflective coating. The first anti-reflective coating may further include a ratio AC1.sub.SiO2/AC1.sub.B of at least about 0.01 and not greater than about 1.3. The composite film may further have a VLT of at least about 93.0% and a haze value of not greater than about 3%.
