摘要:
A process for the preparation of a package containing a compacted particulate composition, comprises wrapping a compacted particulate composition with a first film and treating the wrapped compacted particulate composition at an elevated temperature to shrink the film such that it clings to said composition. The resulting packages maybe made using low compaction pressures and consequently may have low friability and be fast dissolving.

A conveyor system is provided including a conveyor and a plurality of functional trays that are removably attachable to the conveyor. Each tray includes a plate having first and second dimensions that are orthogonal to each other, and the plate includes a coupler configured to be removably attached to the conveyor with the second dimension of the plate being in parallel with a moving direction of the conveyor. The plurality of functional trays include one or more of an envelope-opening mechanism, an item-pushing mechanism, an envelope-closing mechanism, an item-wrapping mechanism, and a tray-height-adjustment mechanism. For example, the item-pushing mechanism includes a pusher slidably coupled to the plate, and a linear actuator configured to move the pusher relative to the plate along the first dimension so as to push an item off the functional tray.

A method and a device (12) are disclosed for handling flat and/or foil materials (26) wound on rolls (14, 15) and used as packaging material for the packaging of piece goods, containers or similar assemblies of articles. In order to maintain a packaging operation, an at least partially unwound and/or depleted roll (15) is removed from at least one mounting position (EB1; EB2) of a packaging machine (10), and respectively exchanged for a new roll (14) comprising flat and/or film material (26), in that after each positioning of a new roll (14), the outermost layer (36) thereof is drawn off near to or in the region of the free end (50) thereof and connected, in particular welded or bonded, to a section of a material web (26) guided into a packaging line, so as to form an uninterrupted material web (26). The material web (26) drawn off from each new roll (14) is grasped by means of a controllable gripping and/or handling device (52) and moved in the direction towards the material web (26) that is already guided in the packaging line and/or to an attaching and/or welding device (32).

A bottle packaging system in a bottling line comprises the following components: a pick-up device (2) having a rotating carousel to pick up the bottles (11) from a labelling or filling machine (1), a rectilinear, multi- lane (4, 4') conveying belt (3), a packaging machine, such as a shrinkwrap machine (6) or a cartoning machine, a transport system (7) to connect the packs exiting from the packaging machine (6) with downstream devices, wherein this system comprises, at a grip circumference (C) of the rotating carousel (2), which corresponds to the point of release of the bottles (11) by gripping means (13), a connecting zone (12) with the conveying belt (3), wherein the connecting zone (12) is constituted by a plurality of adjacent flexible chain belts with a spiral progression, that is to say, with increasing curvature radius, which constitute as many lanes (14), adapted to support and distance, in a centrifugal direction, the bottles (11) released thereon by the gripping means (13), directing them into the corresponding lane (4, 4') of the conveying belt (3), the lanes (14) of the connecting zone (12) underneath the rotating carousel (2) being in a position of intersection (X) with the grip circumference (C).

Heat-shrinkable monolayer and multilayer films are disclosed. The films are formed of a blend of a polyethylene copolymer having a CDBI of at least 70%, a melt index I2.16 of from 0.1 to 15 g/10 min., a density of from 0.910 to 0.940 g/cm3, a melt index ratio I21.6/I2.16 of from 30 to 80, and an Mw/Mn ratio of from 2.5 to 5.5, and a second polymer, such as a low density polyethylene (LDPE). The heat-shrinkable films have a combination of improved optical and mechanical properties.

The invention relates to a method for wrapping a stretch film around a bunch of containers comprising at least three round containers that are positioned and retained by a retainer device while the stretch film is wrapped around the bunch. The inventive method is characterized in that a) the stretch film (3) is coiled up, preferably to a multi-layer tubular section, outside the retainer device of a coiling drum that is separate from the bunch of containers, b) radially widening said tubular section, and c) pushing the film in the widened state across the bunch of containers from the side opposite the retainer device, before d) releasing the tubular section so that it can cling to the container (9) under prestress in such a manner that due to the elastic restoring forces of the stretch film (3) the film and the bunch of containers wrapped into said film give a solid connection.
