| (54) | Flexible container to be filled with bulk material and method for its manufacture |
| (57) The present invention relates to flexible containers to be filled with bulk material,
and their manufacture. The container has at least one lifting loop (6) which is gathered
in a lifting loop having a permanent lifting handle (10) comprising the lifting loops
(6) folded or pressed together and joined by means of glue or a seam in a lifting
area (4). The lifting handle (10) may comprise a piece of material (5) which at least
covers the lower part of the lifting area (4) which has a width < 1/6 of the container's
circumference. The container is made from a flat-woven or round-woven base material
(1) which is joined for forming at least one integrated lifting loop (6). Those parts
of the base material (1) which shall form the lifting loop (6) are folded to at least
one lifting area (4). It might possibly be fastened to a piece of material (5) to
at least the lower part of the area (4). By joining of the area (4) and/or fastening
the piece of material (5) there is formed a permanent lifting handle (10). The piece
of material (5) which is fastened around the area (4) can be in form of a sleeve and
have the same width as this area. |
