The present invention relates to a method for making airtight packages (100) made of flexible material that are configured to seal an environment inside the package with respect to an external environment, said packages (100) comprising a front panel (1), a back panel (2) and two side gussets (3, 4) provided at opposite ends of the front panel (1) and of the back panel (2) so as to connect the front panel (1) to the back panel (2). The method comprises a first step of folding a sheet (60) made of flexible material along two first fold lines (L1) which are mutually parallel so as to form a tubular element (61). Moreover, the method comprises a second step that consists in folding an end portion of the tubular element (61) along two second fold lines (L2) that are oblique with respect to the direction of the first fold lines (L1) so as to form an end portion of the tubular element (61) that has two triangular portions (6, 7) having two mutually parallel sides (8, 9) and having a distance between each other equal to twice a first predetermined distance (D1). In addition, the present invention also comprises a machine (200) which allows using such method and a package that can be made by means of such method and such machine.

A system for manufacturing a flexible bulk container. The system includes workstations circumferentially spaced apart from each other. Each of the workstations is operable to perform an operation on a preform of the container. The workstations sequentially modify the preform from an initial version to a final version, the final version of the preform being the manufactured flexible bulk container. A preform manipulation apparatus includes a carrousel disposed centrally and being rotatable about a vertical central axis. Manipulation arms are mounted to the carrousel for common rotation therewith. The manipulation arms each have a proximal end fixed to the carrousel and a distal end having a manipulation tool mounted thereto for seizing and manipulating the preform at each of the workstations. Each of the manipulation arms in operation displaces the manipulation tool and the preform between successive workstations. A method for forming a flexible bulk container is also disclosed.

A full recycling environmental protection packaging structure applied to express deliveries, postal services and logistics and made of a planar structure of paper. The packaging structure includes a first surface and a protecting layer overlapped on the surface. The protecting layer includes at least one layer of liner which is a three-dimensional network structure. The packaging structure of the present disclosure can overcome problems that kraft paper bubble bags or envelopes, and paper and plastics can't be separated and recycled to pollute environment in the prior art. At the same time, it can solve technical problems of dust pollution and poor air quality caused by using powdery and granular soft structures used as buffers.

A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sleds stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.

Provided is a bag making and packaging machine having superior workability in film joining work. A bag making and packaging machine is a bag making and packaging machine that uses film having at least one character or a figure printed on its front side, and is equipped with a film roll support unit, a conveyance unit, a bag making unit, and a light emitting component. The film roll support unit supports a film roll in which the film is wound in a roll. The bag making unit processes the film to make bags. The conveyance unit is positioned between the film roll support unit and the bag making unit. The conveyance unit feeds the film to the bag making unit. The light emitting component illuminates, from the direction of the front side of the film, the film positioned between the film roll support unit and the conveyance unit.

An incision station for making a plurality of weaknesses respectively on a plurality of portions of a web, for producing a plurality of packages each of which including a supporting sheet corresponding to a respective portion of the portions and an opening system corresponding to the weakness made on the respective portion, which makes it possible to increase the precision in obtaining the opening system of each package and to increase the productivity of the packaging machine in which the above-mentioned station operates. This invention also relates to a packaging machine which includes the incision station and a incision method for making the above-mentioned plurality of weaknesses, in such a way as to achieve the above-mentioned aims.

A full recycling environmental protection packaging structure and a manufacturing method thereof applied to express deliveries, postal services and logistics and made of a planar structure of paper. The packaging structure includes a first surface and a protecting layer overlapped on the first surface. The protecting layer includes at least one layer of liner which is a three-dimensional network structure formed by paper material being stretched after being die-cut. The planar structure is sealed edges thereof and an opening is reserved to form a bag body. The packaging structure of the present disclosure can overcome problems that kraft paper bubble bags or envelopes, and paper and plastics can't be separated and recycled to pollute environment in the prior art. At the same time, it can solve technical problems of dust pollution and poor air quality caused by using powdery and granular soft structures used as buffers.

A method for producing a bag from a tube including transverse lines of perforations delimiting tabs of the future bag, a rear tab of a first bag being opposite a front tab of the second bag following the first. A first step involves separating the first and second bags; a second step involves separating a piece of waste remaining on one of the bags between the two tabs. The first and second steps are carried out between a first pair of separation cylinders and a second pair of cylinders, the piece of waste being clamped between the cylinders of the first pair during the first step in order to be held on the second bag, then clamped and torn off by the second pair during the second step.
