Abstract
A composite stretched film having one surface adhesive, while the other nonadhesive is wrapped spirally or helically about an article to be packed to form first and second superposed layers. After forming a first layer, the composite film is inverted so that the first and second layers are bonded together with their adhesive surfaces, while the nonadhesive surface of the first layer is brought to contact with the article and the nonadhesive surface of the second layer is faced outward.
