A COATED FABRIC, A BAG PRODUCED THEREFROM, A PACKAGING MACHINE FOR BAGS AND A METHOD FOR FILLING THE BAGS.

摘要

A coated fabric (11), comprising a fabric (12) from polymer tapes (12a, 12b), wherein the fabric (12) is coated with a sealing layer (13), wherein ⠢ at least a portion of the polymer tapes (12a, 12b) have a breaking tenacity of less than 45 cN/tex, preferably 15 to 40 cN/tex and an elongation at break of more than 30%, preferably of 40 to 90%, and/or ⠢ wherein the sealing layer (13) is formed from a composition A comprising at least one ethylene/α-olefin interpolymer, and wherein the composition has a density from 0.905 to 0.930 g/cc, preferably from 0.910 to 0.930 g/cc (1 cc = 1 cm3), and a melt index (12) from 3 to 20 g/10min and a bag comprising said fabric; a packaging machine (100) for filling gusseted (220) bags (10, 200) wherein the bag walls (202) of the bags (10, 200) consist of a woven fabric (11) of polymer tapes (12a, 12b) at least in part and wherein each of the ends (203, 204) of the bag wall (202) is provided with a filling mouth (211) for filling, wherein a closing device (125) is provided which is structured such that as the filling mouth (211) is closed a welding temperature of at least 50 Kelvin higher in the region of the gussets (220) than in a center region (223) of the bag wall (202) can be generated.
