  • Patent number: 5102715
    Abstract: An article for preserving fresh cut flowers placed in water, which is in the form of a label applicable to one or more stalks of the cut flowers. The label has a water insoluble carrier layer, a coat of material applied to the carrier layer containing an active material and a barrier layer to water applied to the coat. The active material comprises at least one active substance which sets free bactericidal and/or bacterial inhibiting agents in the presence of water. The barrier layer in cooperation with the carrier layer regulates the size of the total contact surface of the water with the active material and consequently the release time for the active substance when the label is immersed into the water.
