Claims10
An adhesive label comprising
- (a) a substrate having a first surface and a second surface;
- (b) a layer on the first surface consisting essentially of a hydrophilic composition, wherein the composition comprises:
- (i) a complex of 1-methylcyclopropene and a-cyclodextrin;
- and
- (ii) a polymer binder selected from the group consisting of polyvinylpyrrolidone and copolymers thereof, polyvinyl alcohol and copolymers thereof, polyvinyl acetate copolymers, and combinations thereof;
- (c) at least one additional functional layer covering the layer on the first surface;
- and
- (d) an adhesive provided on the second surface;
- wherein the hydrophilic composition is capable of releasing the 1-methylcyclopropene in the form of a gas when exposed to moisture, and wherein the at least one additional functional layer changes the 1-methylcyclopropene release profile relative to what the 1-methylcyclopropene release profile would be in the absence of the layer.
