<p>A method for manufacturing a packing cushioning material, comprising: (a) preparing a roll (3) of plastic material having a plurality of pre-prepared two-dimensional non-inflated cells (2) by connecting two sheet layers (1) of said plastic material by soldering or welding seams (7) so as to form a double plastic film consisting of said cells (2) and having a passage (5) for inflating the cells (2), each of the cells (2) having an opening (4) into said passage (5) and said cells (2) being separated from each other by these seams (7) and, optionally, by perforation; (b) inflating each of the cells (2) with a blower (9) through the passage (5) while unrolling said roll (3) and thus blowing the cells (2) up into cushions, the air pressure in the cells (2) being about the atmospheric pressure; (c) sealing each cell (2) by welding immediately after inflating it; (d) cutting pieces of the inflated output cushioning material at a required length. The invention further relates to a device for use of this method.</p> |
