Abstract: A novel tear strip or sealing strip for a package or container is disclosed. The tear strip or sealing strip comprises a plastic film substrate upon which a magnetizable metal oxide coating has been deposited. The coated strip may be adhered to the package or the flexible wrapping material for the package or container. Optionally, the strip may be coated with a pigment or metallized or printed with graphic indicia or any combination of these features. Information may be recorded on the magnetic coating during packaging and handling for subsequent readout.

Abstract: A cigarette is provided which includes a corrugated wrapper. The corrugated wrapper is constructed such that the outer surface and the inner surface are separated by a distance which is less than the minimum transverse dimension of the tobacco rod. The corrugated wrapper, when incorporated in a cigarette, provides a cigarette in which firmness and rigidity can be made independent of the density of the smoking material.
