ABSTRACT:
Laminated packaging material includes a corrugated inner ply, a paperboard outer ply having a detachable coupon portion outlined with a perforated die cut, an adhesive between facing surfaces of the outer ply and the corrugated inner ply for adhering the facing surfaces to one another, and an adhesion-preventing agent on the detachable coupon portion of the facing surface of the outer ply for preventing adhesion of the detachable coupon portion to the corrugated inner ply. The laminated packaging material may be manufactured according to a first sequence of steps wherein the adhesion preventing agent is applied to the detachable coupon before the detachable coupon is outlined with a perforated die cut, and the adhesive is applied only to the corrugated inner ply. Alternatively, the laminated packaging material may be manufactured in accordance with a second sequence of steps wherein the detachable coupon portion is first outlined with a perforated die cut, the adhesion-preventing agent is subsequently applied to the detachable coupon portion, and the adhesive is subsequently applied to at least one of a facing surface of the corrugated inner ply and a facing surface of the paperboard outer ply which includes the adhesion-preventing agent. A long slot and/or a tab may be provided along one edge of the detachable coupon to facilitate removal of the coupon.
