A method and apparatus for making pouches is disclosed. It includes using one or more of the following features: using two servo motors to drive a platen, providing a calibration routine is run at start-up and/or after the machine has been operating; controlling in response to feed back from the servo motor(s) such as feedback indicative of the distance the platen travels; the feedback is not of force exerted by the platen; and/or the platen is controlled to prevent unacceptable fracturing of the film laminate.

The invention relates to a method for producing at least one stack (9) formed of bags (1), comprising the following steps: feeding tubular or semitubular material in order to form a bottom material layer (2) and a top material layer (3), introducing at least one weld seam (4) in order to connect the bottom material layer (2) and the top material layer (3) in order to form individual, but still connected bags (1), introducing a formatting fold (8) into the layer web, formed of still connected bags (1), separating the bags (1) connected in the formatted layer web into individual bags (1), wherein said bags (1) still have the formatting field (8), forming a packet of individual bags (1) into a stack (9) having a defined number of bags (1), and introducing at least one fold into the stack (9). The invention further relates to a bag (1), a stack (9), and a dispensing box (12).

A bottom-gusseted package comprises 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 cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Cooperating heat-sealing jaws, including cooperating U-shaped sealing surfaces, act to integrate and seal each individual sleeve with the flexible web to form the bottom gusset of each package, with the heat-sealing jaws preferably configured to include cooperating top sealing surfaces for simultaneously forming a top seal in an adjacent one of the packages.

A bottom-gusseted package comprises 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 cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Optionally, the individual sleeve portions can be configured such that when the flexible web is cut to form individual packages, and each individual sleeve is be cut to form a bottom gusset in one package, and a top sleeve portion in an adjacent package.

A method for making a film bag with reinforced bag seams includes a film extruder that produces a continuous tube of film. A flattener produces a continuous web of flattened film which has an upper surface and a lower surface. A fold maker has a receiving portion positioned above the web and a displacing portion is positioned below the web that moves cyclically upward to a first position to locate a portion of the web into the receiving portion, thereby forming a fold. A fold retention device prevents the fold from opening. A presser flattens the fold against the web. A sealer seals through the fold, forming a reinforced bag seam. A cutter severs a sealed portion from an unsealed portion of the web. A transport mechanism moves the film from the extruder, through the flattener, into the fold maker, beneath the presser, into the sealer and to the cutter.

A bag including a containment portion having an opening to receive items, a bag seal at an end of the bag opposite the opening, a handle seal at an end of the containment portion opposite the opening, the handle seal located between the bag seal and the opening, and a handle in a handle body formed between the handle seal and the bag seal.

Provided is a film processing device including: a first cutting blade and a first receiver base that are opposed to each other with a film including at least two layers interposed therebetween, and are configured to move toward and away from each other; and a first distance adjuster that adjusts, without being in contact with the film, a minimum distance between the first cutting blade and the first receiver base.

A punching machine includes a punch blade and a support for supporting a spout. The punching machine further includes a drive mechanism. When the punch blade and the spout supported by the support face each other in a direction perpendicular to a web with the web interposed between the punch blade and the spout, the drive mechanism moves one of the punch blade or the support towards the other in the vertical direction to punch a hole in the web using the punch blade and the spout.

A bag includes a peelable portion and first and second panel parts facing each other. The bag is configured to be openable by peeling off the peelable portion. The peelable portion includes at least one joined region in which the first and second panel parts are joined to each other, and release agent application regions in which the first and second panel parts are prevented by a release agent intervening therebetween from being joined to each other, the release agent application regions being present in a pattern.

A system and method of manufacturing reinforced bags having reinforcing elements applied about the bags to support the bags in an opened and/or upstanding configuration. A web of bag material can be fed from a supply and can be folded and secured to form the bags. A series of reinforcing strips can be fed through an adhesive application station for application of an adhesive material thereto in a desired pattern. The reinforcing strips and bags are brought into registration and are adhesively attached to form the reinforced bags.
