A method and apparatus are provided for the automated wrapping of a bundle with a resilient stretchable film. The method comprises the steps of (i) unrolling a desired length of the film from a roll. The film has a first panel overlapping a second panel. The panels are interconnected at a sealed first end. (ii) Sealing a second end of the panels to bond them together by a second seal at the desired length. (iii) Cutting the film along the second seal to form a tube. (iv) Separating the first panel of the tube from the second panel by grasping film edges of each of the panels, whereby the tube may be opened. (v) Loading the tube in an opened position on an expandable frame, whereby at least a portion of the tube is accumulated in a folded condition on the expandable frame. (vi) Stretching the tube by expanding the expandable frame. (vii) Covering the bundle with the tube, by displacing the expandable frame towards the bundle, whereby the stretched tube is gradually released therefrom onto the bundle in a stretched resilient condition.
