    Patent number: 5716695
    Abstract: A laminated multilayer film substrate for use in the production of banknotes. The film substrate includes a first layer comprising at least about 50 weight percent of a high density polyethylene having a density of at least about 0.95, the first layer oriented in at least a first direction to a degree which is at least three times greater than the degree of orientation present in a direction substantially normal to the first direction, and a second layer comprising at least about 50 weight percent of a high density polyethylene having a density of at least about 0.95, the second layer oriented in at least a first direction to a degree which is at least three times greater than the degree of orientation present in a direction substantially normal to the first direction, wherein the second layer is laminated to the film substrate so that the first direction of orientation of the second layer is substantially normal to the first direction of orientation of the first layer.
