A flexible gusset package containing a plurality of items is described. The package has a front surface having no seam; a rear surface opposite the front surface; a first surface adjacent the front and rear surfaces; a second surface having a closing seam and being opposite the first surface; an opposing pair of third and fourth surfaces respectively adjacent the first and second surfaces, the third and fourth surfaces having a first and second side seams, respectively; a pair of side gussets located in the third and fourth surfaces, respectively; and a pair of closing gussets located in the second surface, wherein the surfaces cooperatively define an interior compartment of the package, wherein the package is a laminate having a film layer facing the interior compartment and a paper layer, and wherein the second surface includes an area of the film layer where the closing seam is formed.

A packaging machine has at least one carriage including a carriage body defining an internal passage dimensioned to receive a packaging sleeve, the internal passage extending along a passage axis with a passage sidewall extending therearound. A retention mechanism is configured to retain the packaging sleeve against the passage sidewall, one or more packaging subsystems are configured to perform an operation on the packaging sleeve, and a drive mechanism is configured to move the carriage to and from the packaging subsystem. Opposite ends of the internal passage along the passage axis can both be completely open from the passage axis to the passage sidewall. The retention mechanism can be configured to retain the packaging sleeve with vacuum. The packaging subsystem can include one or more of a sleeve infeed device, a sleeve spreader device, an indexing device, and a sealing device.

A bag includes a body with a closed and stepped end, and an opening in the closed end as a handle. A tube having a first panel, a second panel and two side gussets is provided. The tube is foldable inward along a longitudinal fold line on each of the two side gussets. A stepped end is formed. The first panel has a first longitudinal length, the two side gussets have at least one portion having a second longitudinal length, which is longer than the first longitudinal length and shorter than a length of the second panel. The second panel of the tube is folded along a latitudinal fold line between the top line of the first panel and the top line of the tube so as to form the closed end. The opening is cut in the closed end.

A bag making apparatus includes an intermittent feed device for feeding sheet panels, an adjustment device for detecting upper and lower thresholds for a length of the sheet panels included in a section from a first drive roller pair to a second drive roller pair, a movement device for moving a processing device and a sensor together as a movable group in the longitudinal direction of the sheet panels. The movement device moves the movable group upstream in response to the adjustment device detecting the upper threshold and moves the movable group downstream in response to the adjustment device detecting the lower threshold. If the movable group is moved, the intermittent feed device determines an intermittent feed distance based on a moving distance of the movable group in addition to output from the sensor and feeds the sheet panels by the determined distance using the first drive roller pair.

A machine for producing bags includes a station for forming a tube, which forms a band of transversely perforated flexible material into a tube, a holding station for retaining the tube, a folding station for forming a bottom at the end of the tube, a folding roller having a folding blade for folding a flap at the end of the tube and a tear-off bar for pinching the tube against the drum, the folding station and the holding station being configured to jointly exert a traction on the tube and detach a portion of the tube. The tear-off bar is disposed behind the folding blade, the machine controlling the rotation of the folding station to synchronize the drum with the front of the tube.

The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape has at least one stretched elastomeric strip attached to the draw tape in an extended condition. The draw tape may be smaller in size than the bag sidewalls. The draw tape may include an elastic characteristic, such as patterned ribs. In one embodiment, the roll of bag is kept under tension to maintain the elastomeric strips in a stretched condition.

Peelable seals including porous inserts are described. An example peelable seal includes a porous insert positioned between a first sheet and a second sheet. The porous insert includes a plurality of interwoven strands and a plurality of pores adjacent the interwoven strands through which a bond is formed between the first sheet and the second sheet when heat is applied to at least one of the first sheet, the second sheet or the porous insert.

A package made of fibre material has at least a first wall and a second wall, as well as an adhesive stripe between the first wall and the second wall. The adhesive stripe constitutes a seam closing the package on that side of the package where the package is arranged to be opened. The paper package further has at least one fibre rip stopper at the edge of the adhesive stripe or at a distance from it in the direction of the interior of the package, the stopper being arranged to delimit the point separating the first wall and the second wall to the edge of the adhesive stripe or to a distance from it in the direction of the interior of the package when the package is opened. The disclosed embodiments also relates to a method for making a package of fibre material.
