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. Tape elements are applied in overlapping relationship to opposite ends of each individual sleeve. During package formation, the flexible web is cut to form individual packages, and each individual sleeve can be cut to form a bottom gusset in one package, and a top sleeve portion in an adjacent package. A top sleeve portion of the package body can be configured to include a reclosable fastener. The tape elements facilitate formation such that the packages can be formed and filled on an associated vertical form, fill and seal apparatus have conventionally configured heat-sealing jaws.

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 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.

The provided are a four side seal packaging bag and a preparation device and method thereof. The preparation device includes at least: a film material conveying mechanism, configured to continuously convey a film material of a packaging bag along a length direction of the film material; a folding mechanism, configured to fold the film material conveyed by the film material conveying mechanism; a cutting mechanism, configured to cut the upper film material; punch-and-cut mechanisms, configured to form square punch-and-cut regions and separate the square punch-and-cut regions from the side accordion film materials; a side accordion forming mechanism, configured to perform a forming operation on the side accordion film materials; and a hot-sealing mechanism, configured to hot-seal the upper film material, the formed side accordion film materials, and the lower film material.

A trifold side seamed film produce bag includes a front wall and a back wall, first and second side edges sealed together and a seamless bag bottom. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. An apparatus for forming the side seamed bags includes an extruder, a tubing flattener, a perforator, a sealer, a corona treater, a printer and a slitter. The treated, printed bags may be stored on rolls for later slitting into two bag streams and folding into thirds.

The invention relates to a receptacle (10), in particular a flexible bag (10) made of paper, with a front part (20), a back part (30) and a bottom (50), which is closed by a bottom unit, and with an opening (1) lying opposite the bottom (50), wherein the bottom unit has a bottom portion (120) of the front part (20) and a bottom portion (130) of the back part (30), the bottom portion (130) of the back part (30) is shorter than the bottom portion (120) of the front part (20), such that the bottom portion (120) of the front part (20) is secured directly on the back part (30) by turning the bottom unit (100) back along a fold line (101), and the opening (1) is formed by a peripheral edge (2) which extends at a height of the front part (20) and of the back part (30) and which is at least partially frayed, thereby reducing the danger of injury at the edge (2).

A fixture mounting assembly facilitates efficient and convenient mounting of lighting fixtures and like elements on various types of ceiling mounting components. In one embodiment, the mounting assembly in configured to readily adjustable in length, with the adjustable nature of the assembly facilitating versatile use by permitting convenient adjustment of the assembly to accommodate different, typically standardized spacing of the mounting components. In this embodiment, the assembly includes first and second, inner and outer channel members arranged in sliding, telescopic relationship. The channel members define and arrangement of openings and slots to facilitate fitment to different types of ceiling mounting components. The telescoping nature of the channel members facilitate their fitment to associated ceiling mounting components which may have different, standardized spacing. Efficient and versatile use desirably offers significant savings in time and installation costs for fixture installation. In alternative embodiment, a fixture hanger assembly includes a pair a substantially identical channel members configured for efficient fitment to so-called hard-lid/hat-rack ceiling components.

In order to successively make plastic bags each of which includes panel portions, side gusset portions and a zipper portion, a web of panel material 9 is folded and folded back along longitudinal folded lines 14, 15 and 16 and longitudinal folded back lines 17 and 18 into superposed two layers having opposite side edges at each of which a folded portion is formed. The web of panel material 9 is slit along the longitudinal folded line 16 into two divided parts after being folded and folded back. The divided parts are separated and spaced from each other. In addition, the folded portions are split at positions into sprit portions and removed at the positions partially, a body of zipper material being disposed between the sprit portions.
