A method for manually applying web-like material, such as plastic stretch film in roll form, to packaging units, by winding the web material about the packaging units and controlling the tension and speed of unrolling of the roll of web material while applying the latter to the packaging units, and a simplified tool for accomplishing the method. The tool includes a head and a spindle projecting outwardly therefrom, with the head being adapted to mount a roll of the web material in non-movable relationship with respect to the head. An encircling wrap envelope of the web material is wound about the spindle in relatively rotatable relation therewith, and the tension and speed of unrolling of the web material from the roll while applying the web material to a packaging unit is accomplished by manually squeezing the wrap envelope of material on the spindle, to selectively cause a braking action between the spindle and the envelope.
