A lap seal packaging band for wrapping or bundling objects. The band is formed from two overlying strips at least one of which is a non-woven material. The strips may be unequal or equal in length and at least one end of one strip is exposed. One or both of the strips are coated with a water borne pressure sensitive adhesive or both strips are coated with a water borne pressure sensitive cohesive. The exposed end or ends are bonded after coiling to form a band. The band may be readily opened by manually transversely tearing or by manually peeling the sealed end or ends. The strips of substrate may be of different materials and the water borne bonding agents may be different to achieve different properties in the resulting band. The coatings may be curable by air drying, heat drying or chemical content to vary the bonding properties of the coatings.
