Abstract
The present invention relates to a protective wrapping medium, for particular application to large rolls of metal sheeting by automatic wrapping machines, for example as used within the steel and aluminum sectors, that is designed to provide both protection against physical damage which may occur during transport and/or storage, in addition to protection against chemical corrosion, while permitting printed branding to be incorporated into the wrapping medium if desired, the wrapping medium having a substrate with opposed first and second surfaces, with a first layer of cohesive material (22) applied as a substantially longitudinally extending band on the first surface adjacent a first edge of the substrate, and a second layer of cohesive material (24) applied as a substantially longitudinally extending band on the second surface adjacent a second edge of the substrate.
