Fluid activatable adhesive labels, label systems, and methods of making and using thereof are described herein. These labels are particularly useful with facesheets with low MVTR due to the inclusion and placement of sequestration components within the labels. The sequestration components are either embedded in an adhesive layer, in a separate tie-layer between the adhesive layer and the substrate, incorporated in the substrate, or incorporated into the adherend. Preferably the labels are clear. Following application of an activation fluid and, preferably following activation of the activatable adhesive layer, the sequestration materials adsorb the fluid from the polymer adhesive components over time, such as for about 0 to 72 hours This dries the label and wets the sequestration components. Optionally, the container with the label is also subjected to a drying step to dry the sequestration components. |
