Abstract: The present invention is a laminate and resultant package expressing an aroma burst. The laminate or package is comprised of a polyolefin sealing layer; a pressure sensitive adhesive layer and microcapsules containing an active core material, the microcapsules dispersed in a resealably tacky pressure sensitive adhesive layer; the pressure sensitive adhesive sandwiched between at least two layers by being disposed along substantially an entire surface of the polyolefin sealing layer and in continuous and direct contact with a second polyolefin layer opposing and coextensive with the polyolefin sealing layer; and the microcapsules in the pressure sensitive adhesive layer having less tensile strength than the adhesive such that a fraction of the microcapsules rupture releasing core material such as an aroma or fragrance when the pressure sensitive adhesive layer is separated when the polyethylene and first polyolefin layers sandwiching the pressure sensitive adhesive are pulled apart.

Abstract: A lap sealable laminate is provided comprised of an oriented polypropylene film layer on one side of the laminate, and a polyolefin elastomer-modified polyethylene sealant film forming an opposing side of the laminate, as well as a flexible pouch formed from the lap sealable laminate.
