Abstract (en)
[origin: WO03062089A2] A tubular element (1) for forming bags (14) for the vacuum packaging of products (17), particularly perishable products, comprises one or more walls (2) which are impermeable to gases and at least one dividing sheet (3) substantially impermeable to liquids and interposed between the walls (2). The walls (2) and the dividing sheet (3) are connected along longitudinal sides (4) to form a tubular body with two or more chambers (5, 5'), each chamber (5, 5') being at least partially delimited by the dividing sheet (3). The dividing sheet (3) comprises a continuous, liquid-tight, central layer (12) from which projections (8) extend into both adjacent chambers (5, 5'), the projections (8) defining, together with regions (13) of the surfaces of the central layer (12), a system of suction channels (9).
