Systems, methods, and computer-readable media are disclosed for defect prevention for flexible container sealing systems. In one embodiment, an example flexible container sealing system may include a first camera configured to image an item disposed in a flexible container, a laser system configured to detect presence of items, a cutting assembly configured to cut a material that forms the flexible container, a sealing assembly configured to seal one or more ends of the flexible container, and a computer system configured to determine, using the first camera, a height of the item disposed in the flexible container.

A cyclic packaging process, such as VFFS or HFFS, packages a product with a viscosity of ≥100,000 centipoise without leaving substantial air pockets in the package, by utilizing a means (38) for restricting upstream flow of viscous product in the strand of tubing (24). The result is that packages of uniform weight of the viscous product can be made without substantial air pockets therein, and without having to use metal clips. An apparatus (10) for carrying out the process is disclosed.

A conveyor capable of detecting a cut line of portion packaging bags, and a medicine inspection support system are provided. The conveyor conveys the portion packaging bags to an inspecting machine, the portion packaging bags being divided one by one with use of a heat seal portion and perforations by a portion packaging machine and being continuously discharged in a longitudinal posture from the portion packaging machine. The conveyor includes a posture changing device configured to change the longitudinal posture of the portion packaging bags to a lateral posture; and a detector configured to detect a cut line of the portion packaging bags.

A bag-making and packaging machine includes sealing jaws, a horizontal moving device, a vertical moving device, and a control unit. The sealing jaws perform a transverse sealing operation. The vertical moving device moves the sealing jaws in a vertical direction. The vertical moving device includes a rotating shaft, a motor, and a link mechanism. The link mechanism transmits rotational force of the rotating shaft to the sealing jaws. The control unit performs first control or second control. The first control forwardly rotates and reversely rotates the rotating shaft during a period of time from a start of the transverse sealing operation to a start of a subsequent transverse sealing operation. The second control performs one of the transverse sealing operation and the subsequent transverse sealing operation with a forward rotation of the rotating shaft and the other with a reverse rotation of the rotating shaft.

A packaging apparatus for small piece goods, the use of the packaging apparatus, and a method for producing a blister tube are provided. The packaging apparatus includes a packaging material guiding device for providing a shaped packaging material web suitable for receiving small piece goods, a longitudinal joining device which is arranged downstream of the packaging material guiding device and a transverse joining device which is arranged downstream of the packaging material guiding device. The transverse joining device joins the shaped packaging material web together at predetermined intervals transversely to the direction of travel to form a transverse joining area. The transverse joining device includes two joiners, which have a plurality of embossers that are individually movable transversely to the direction of travel and have an embosser stop area which cooperate such that elevations that are palpable are formed by the embossers in the transverse joining area.

A shippable bundled product including a plurality of paper product rolls each individually packaged by a first package material and arranged relative to one another so as to form a bundle. The bundle is packaged by a second package material. The second package material has a shrinkage factor relative to the bundle of less than zero and the bundle has a size of 18 in. x 14 in. x 8 in.

Vertical flow-wrapper that includes a frame, a web feed, which feeds a web to a form-shoulder, and a form-fill tube, which forms the web into a web tube, a longitudinal sealing-means to seal longitudinal edges of the web tube together, and a cross sealing means to provide a cross-seal to the web tube. The cross sealing means includes seal jaws, a closing motor, and a jaw closing mechanism; the seal jaws and the jaw closing mechanism reciprocate between an upper and lower vertical position; the closing motor is provided at the frame and a torque transfer means is provided between the closing motor and the jaw closing mechanism; the closing motor and the reciprocation motor are operated independently from each other; and the closing motor is connected to the frame by a slide bearing or is pivotably connected to the frame.

A working process of a machine for wrapping products in packages, carried out with a thermoplastic material film from a reel, the process comprising: reducing a transversal section of a hollow mandrel to be smaller than a transversal dimension of a bundle of products, positioning a sealing device in a position for sealing overlapped longitudinal edges of the film while forming a new tubular film casing, arranging two vertically mobile elements of a sealing and transversal cutting assembly in a closure position on the head portion of the new tubular film casing and on the tail portion of the tubular film casing of a finished package, and conveying the new tubular film casing away from the mandrel, and repeating the process so that the product placed inside the tubular casing by the mandrel is wrapped in a tight adherent manner due to the elastic retraction of the film.

The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which delimit a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings, and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall or the cover strip, and/or the parallel fastening strips consist of stretchable material.
