A laminate comprising first and second laminae. An active is disposed between the first and second laminae. At least one of the laminae is permeable to the active. Holes may be provided to make that lamina permeable. The active is extruded through the holes upon pressure applied generally perpendicular to or in shear relative to the plane of the laminate. The active may be a pressure sensitive adhesive. The laminate is usable as a wrap to temporarily seal or otherwise protect contents, which are typically perishable. The contents may be enclosed by the laminate or placed in a separate container which is covered by the laminate. |
