Magnetic tear tape or sealing strip for packaging.

摘要

A novel tear strip (16) or sealing strip (76) for a package (10) or container (68) is disclosed. The tear strip or sealing strip comprises a plastic film substrate (80) upon which a magnetizable metal oxide coating (82) has been deposited. The coated strip may be adhered (92) to the package or the flexible wrapping material (70, 72) 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.
