Abstract: A method of making an intermediate bulk container having zones (12) for the attachment of lifting loops (20) from a fabric (10) having eight such zones with lifting loops attached to the zones comprises attaching the opposite selvedges (14, 16) of the fabric together and then attaching the base (26) to complete the bag. The zones (12) are arranged in four pairs with a zone (12a) of one of the pairs being adjacent to one of the fabric selvedges (14). The side seam (24) of the bag so made is thus spaced from its adjacent corner. This means that all four lifting loops can be attached to the fabric while it is still in the flat state since no lifting loop has to cross the seam in the finished IBC>. This form of construction lends itself to automatic stitching processes and radically increases speed of production.

Abstract: A package is provided which is formed of a plastic film such as polyethylene or polypropylene. The package is formed to define an internal chamber to accommodate an article to be packed.

The top end of the bag may be provided with perforations which may be broken to gain access to the bag contents. The bag may be resealed by means of the handle slide closure.

Abstract: Large size packagings of napkins, paper rolls, quilts etc. normally appear as tight plastic sheet packings of a block-like shape. As a carrier handle is used a strong strip of sheet material which extends across a side panel of the packing, what is disadvantageous for the visual impression of the packing. A carrier handle cannot be formed direct in the packing sheet, as the packing will then no longer be dust proof. A handle is formed wherein inside the handle area, a barrier layer is provided in order to make the packing dust proof. Preferably a carrier handle strip portion is prepared between easily breakable weakening lines, whereby the handle panel of the packing may show a high quality stamp regardless of the handle.

Abstract: Bag segments arriving one after the other in a travel direction at an upstream input station are first lifted one by one as they arrive at the input station, are inverted them, and are deposited in a stack at a downstream stacking station atop one of a pair of similar pin-type stacking carriages held at an upper level. The one stacking carriage and the stack carried thereby are periodically displaced downstream from the stacking station to a downstream station at the upper level and the other stacking carriage is raised in the stacking station from a lower level below the one carriage to the upper level with the one carriage such that the segments are subsequently deposited on the other carriage in the stacking station. The one carriage is then lowered in the downstream station from the upper level to the lower level to strip off the stack it carries and thereafter is displaced at the lower level back upstream to the stacking station.
