Abstract: A laminate material for a flexible packaging is provided having first and second layers. The first layer has a weakened line therethrough that defines a first flap. The second layer is adhered to the first layer and has a second weakened line formed offset from the first weakened line in the first layer and defines a removable panel in the second layer. An adhesive layer is located between the first and second layers. The adhesive layer comprises pressure-sensitive adhesive located inwardly of the weakened line in the first layer and a vacancy located laterally inward of the pressure-sensitive adhesive and adjacent the removable panel. The removable panel remains connected to the second layer when the first flap is peeled back. The removable panel is separately removable from the first flap. The first flap is resealable to the second layer by means of the pressure-sensitive adhesive exposed upon opening the first flap.
