An unpacking system having a folding-out device for folding outwards an initially folded-in packaging portion of an item of packaging for an object, and having a stretching device for stretching an item of packaging for an object. The item of packaging herein is in particular a pouch, and the object is in particular a pharmaceutical or cosmetic object. The unpacking system furthermore has a transportation installation for transporting the object in a transportation direction. The packaging portion in the stretching device is stretched parallel with the transportation direction. A filling system is disclosed having such an unpacking system, and methods are disclosed for folding outwards, for stretching, and for unpacking.

A system for controlling the temperature of a film before and/or during application, the system including: a heat source for heating a film; and stretch rollers; wherein the heat source heats the film from an ambient temperature to a temperature from about 2° C. to about 40° C. above the ambient temperature, wherein the film is heated prior to or simultaneous to being stretched by the stretch rollers, and wherein the ambient temperature is below 15° C. The preheating system may be used to enhance binding and sealing properties of stretch films used for wrapping palletized products in a reduced temperature environment. Other embodiments of the preheating film system, and methods for its use, are described herein.

A method, apparatus and program product perform automatic load profiling to optimize a wrapping operation performed with a stretch wrapping machine. Automatic load profiling may be performed, for example, to determine a density parameter for a load that is indicative of load stability such that one or more control parameters may be configured for a wrapping operation based upon the density parameter. Automatic load profiling may also be performed, for example, to detect a load with a nonstandard top layer, e.g., a load with a top or slip sheet, a load with an easily deformable top layer, a load with a ragged top surface topography and/or a load with an inboard portion, such that a top layer containment operation may be activated during wrapping to optimize containment for the load.

An unpacking system having a folding-out device for folding outwards an initially folded-in packaging portion of an item of packaging for an object, and having a stretching device for stretching an item of packaging for an object. The item of packaging herein is in particular a pouch, and the object is in particular a pharmaceutical or cosmetic object. The unpacking system furthermore has a transportation installation for transporting the object in a transportation direction. The packaging portion in the stretching device is stretched parallel with the transportation direction. A filling system is disclosed having such an unpacking system, and methods are disclosed for folding outwards, for stretching, and for unpacking.

A pallet wrapping system with a pre-stretch carriage and at least two encoders. The pre-stretch carriage is configured to pre-stretch stretch film and has at least two stretch rollers and a hinged door. The at least two stretch rollers includes a first stretch roller with an outer surface that moves at a first speed and a second stretch roller with an outer surface that moves at a second speed higher than the first speed. The door provides access to the stretch rollers when in an open position and entraps the stretch film between the stretch rollers and the door when in a closed position. The encoders are mounted on the door. Each of the encoders is configured to contact the stretch film on the outer surface of one of the stretch rollers and measure a length of stretch film passing over that stretch roller.

A pallet wrapping system with at least two guides sets configured to narrow the width of stretch film to form a banded edge on the stretch film. A plurality of rollers is positioned adjacent to the plurality of guides to facilitate passing the stretch film through the plurality of guides. A first roll of stretch film positioned to pass stretch film to the first set of guides, and a second roll of stretch film positioned to receive banded stretch film from the first set of guides, layer the banded stretch film onto unhanded stretch film to form an unbanded composite stretch film, and then pass the unhanded composite stretch film to the second set of guides to form a banded composite stretch film having a banded first ply with a width equal to the first width and a banded second ply with a width equal to the second width.

An unwinding apparatus associable with a wrapping machine for delivering films comprises a supporting frame to rotatably support a first reel of a first film; adjustment elements to rotatably support a second reel of a second film and to arrange it in one of a plurality of operative positions, in which the second reel is staggered with respect to the first reel; guiding rollers to guide and partially overlap the first film and the second film at a longitudinal partial overlapping band; joining assembly for joining the first film and the second film along a longitudinal joining band made inside a width of the longitudinal partial overlapping band so as to obtain a single-body composite film; the joining assembly comprises a welding device or a gluing device.

A method determines a wrapping configuration of a film wrapped around products to form a palletized load to be moved along a path. The method includes using a defined wrapping configuration, measuring physical quantities acting on the load as a result of movements and/or stresses when the load is moved along different test paths, obtaining a path as a suitable composition of base elementary path stretches, obtaining physical quantities acting on the load along the path as physical quantities associated to the base elementary path stretches, positioning the load on a motion platform, operating the motion platform based on the physical quantities to simulate movements and/or stresses acting on the load moved along the path, checking if the load has remained stable and/or compact, modifying the wrapping configuration if the load did not remain stable and/or compact, and repeating the steps.

A method of wrapping a palletized load includes providing an apparatus with a first wrapping system and a second wrapping system, banding a top edge and bottom edge of stretch film from each of the first wrapping system and the second wrapping system, overlapping the stretch film from the first wrapping system with the stretch film from the second wrapping system to create a composite stretch film, and wrapping the composite stretch film around the palletized load. The edges of the stretch film may be banded by passing the stretch film through a set of adjustment arms. The composite stretch film may have a plurality of sections, where each section is separated from adjacent section by a banded border, a first section, third section, and fifth section each has one layer of stretch film, and a second section and a fourth section each has two layers of stretch film.
