A stretch film supply roll used in stretch wrapping palletized loads includes a plurality of lengths of stretch film wound into a roll form and joined to one another using a plurality of lap seals that forms a continuous web of stretch film on the roll form. Such a stretch film supply roll may be useful, for example, in reuse applications where stretch film is reused multiple times to wrap different loads. In some instances, the lengths of stretch film may have been used to previously wrap different loads, and in some instances, the lengths of stretch film may have differing characteristics such as materials and/or thicknesses.

The invention relates to a method of winding and packaging wide wallpaper, which is wound around a roll on a winding and rotary device, followed by packaging wallpaper in containers for transportation or storage. In the first embodiment of the invention, in the presented process, winding of the wallpaper (3) is carried out onto a winding and rotation mechanism, made in the form of a finished hollow closed cylindrical tube (1) of flexible material, equipped with a valve (2) for supplying and discharging air from it. At the same time, the valve (2) is fixed on one of the tube bases (4). Along the length of the pumped cylindrical tube (1) is fixed the edge of the wallpaper (3) and wound it on the tube (1) until a roll of the required length is obtained. In the second embodiment of the invention, the tube for wallpaper winding is formed from a part of a whole piece of wallpaper material (6) separated from the edge (7) in the form of a fold along the width of the wallpaper. The selected part of the wallpaper material, corresponding to the diameter of the tube (9) being created, is laid in width in two layers and fastened along the perimeter of the formed sides. The valve (10) is installed on one of the bases of the cylindrical tube (9) formed when air is pumped. The rest of the whole piece of wallpaper is wound on the tube (9) until a roll of the required length is obtained. Further, in both embodiments of the described method, the air is released from the tube through the valve to form a flat rectangular structure in the form of wallpaper layers with a tube placed inside. The resulting structure is laid into several layers for packaging in containers and subsequent storage and transportation. Flexible materials such as paper, vinyl, PVC, polyethylene and others are used as material for the manufacture of the tube.
