The dispenser includes upstream and downstream prestretch rollers for engaging and stretching stretch wrap packaging material. The dispenser also includes an intermediate orienting roller positioned between the upstream and downstream prestretch rollers. The intermediate orienting roller abuts one of the upstream and downstream prestretch rollers, and is spaced from the other of the upstream and downstream prestretch rollers. Relative rotation is provided between the dispenser and the load to wrap the stretch wrap packaging material around the load.
