A system comprises a corrugator single facer configured to receive a first web and a second web, to corrugate the first web and adhere the first web in a corrugated state to the second web in an uncorrugated state to form a single face corrugated web as output. The system also includes a folder gluer operatively connected to receive the single face corrugated web from the corrugated single facer. The folder gluer is configured to fold and adhere the single-face corrugated web into a tube.

The invention relates to a production method of a material, a material and packaging intended mainly for food products. The design of the material used in the packaging machines allows for providing handles in the final packaging without the need for secondary operations. The handles are obtained through either placing a secondary narrower web onto the primary material, wherein the handle constitutes said web, or adjacent holes are cut in the primary material, wherein the handle is formed by the holes separating the primary material. A combination of these two methods or materials is also conceivable. In the area of holes, the primary material is joined with the secondary material, which is either a film or a membrane, wherein the secondary material is larger than the holes and it forms an overlap around them. The materials are joined in the overlap area around the inner circumference of the secondary material.

Apparatus for manufacturing an open-mouth bag of at least one layer of a flexible bag material, and method of manufacturing a bag by such apparatus. The apparatus includes a shaping device with a shaping box in the contour of the bag shape to be formed, with a top end and a bottom end, a conveying device for transporting the bag material along the shaping box, a closing device for joining the bag material along the shaping box to form a tube, and a closing station for generating a bag bottom, which is disposed beneath the bottom end of the shaping box. A partial vacuum device is configured to generate intermittently, a partial vacuum. When manufacturing a bag, the bag material is draped around the shaping box in the contour of the bag shape to be formed as continuous material and is joined to form a tube by the closing device.

A bottom-gusseted package comprising a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is folded and cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Attendant to folding of the flexible web, each gusset-forming sleeve is folded. Optionally, the individual sleeve portions can be configured such that when the flexible web is cut to form individual packages, each individual sleeve is cut to form a bottom gusset in one package, and a top sleeve portion in an adjacent package.

The present invention relates to a method for forming packages of flexible material with a first side gusset and a second side gusset starting from a strip coming from a reel having a sliding direction. The method comprises the following steps: making the first gusset by folding close to a first side edge of the strip coming from the reel, and making the second gusset by folding the strip coming from the reel; in which the step of making the second gusset is performed on a portion of the strip which extends in the sliding direction after the step of making the first gusset was performed on the portion of the strip. Moreover, the present invention relates to a machine configured so as to carry out the method.

This disclosure pertains to a forming device used in the formation of a package with a self-mating reclosure, where a single self-mating closure wraps around the periphery of the forming device, and one end of the zipper segment extends into the lap seal of the forming device. Alternatively, one or two ends of the zipper segment could extend into a fin seal. The self-mating reclosure is mounted transversely on the sheet of web or film and includes at least one crushed end proximate to one edge of the sheet of web or film. The self-mating closure may be pre-crushed, prior to attachment to the sheet of web or film, or may be crushed after the sheet of web or film is wrapped around a forming device or similar structure.

A bag making and packaging machine has pull-down belt mechanisms, a transverse sealing mechanism, a rotatable folding member, and a gas blowing mechanism. The folding member, before the transverse sealing mechanism, seals a cylindrical film, pushes against a side portion of the cylindrical film to thereby fold the cylindrical film inward and form a fold in the cylindrical film. The gas blowing mechanism blows a gas onto the fold to thereby inhibit the cylindrical film from sticking to the rotating folding member.

A forming station for forming pairs of three side seal pouches including a shaped outer top surface and an inner forming slot. The inner forming slot has an upper portion extending from an upper entry edge, and a transition portion. The inner forming slot may further include a lower portion.

A system and method for labeling empty transit bags may include applying labels on bag-forming material in a roll form and then sealing and cutting the bag forming material to form individual bags. The size of the bags can be varied to provide a better fit for goods that are subsequently inserted into the bags. Labeling may be done by pre-printed labels provided in a roll stock, or may be blank labels provided in a roll stock that are printed by a printer of the system. Labeling bags when they are initially formed eliminates the need to manually label bags when they are filled with goods.

A bottom-gusseted package is disclosed which includes a bottom gusset positioned transversely of a longitudinal axis of the package, and a top sleeve portion including a recloseable fastener provided at the top of the package. In the illustrated embodiment, the top sleeve portion includes a peel seal positioned above the recloseable fastener. This seal desirably acts to close the two layers of the top sleeve portion at the top of the package for a neat and aesthetically pleasing appearance. The top sleeve portion can also include a frangible region, and at least one grip strip on the interior of the top sleeve portion. The configuration of the package, and its method of formation, permit use with associated form, fill, and seal equipment.
