1. A method of producing a multi-layer article that includes a non-active state and an active state, the method comprising the steps of:
extruding an outer layer having a first side and a second side;
extruding an inner layer adjacent the outer layer, the inner layer being dosed with a volatile material;
bonding the inner layer to the outer layer such that the outer layer and inner layer are bonded in both an active state and a non-active state;
extruding an upper layer including a first side and a second side, the first side of the upper layer being disposed on top of at least a portion of the inner layer and the volatile material therein;
folding the outer layer, inner layer and upper layer such that at least a first portion of the second side of the upper layer is disposed on top of a second portion of the second side of the upper layer; and
applying heat to hermetically seal the first portion of the upper layer to the second portion of the upper layer.
