A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sleds stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.

A primary package (10; 110; 210; 310;510; 610; 810) for being lockably received in an outer sleeve (700), the primary package comprising a main body panel (12; 112; 212; 312; 512; 612; 812) and a retention tab (14; 114; 214; 314; 512; 612; 812) hingedly connected together along a fold line (17; 117; 217; 317; 517; 617; 817), the retention tab having at least one embossment (18; 118; 218; 318; 518; 618; 818), the fold line having been integrally formed in the primary package.

Punched and incised portions can be formed properly, in which it is not necessary to replace an anvil depending on a type of a sheet material. A punching unit 51 comprises: a punching blade 50 for punching a first panel material 11, a second panel material 12, an open tape and a mounting base portion so as to form a punching portion; a incising portion 51 for incising the second panel material 12 and the mounting base portion disposed on the open tape so as to form a incising portion; and an adjusting portion 54 for adjusting a first gap 56 in a punching direction 5Z between edges 50A and 51A of the punching and incising blades 50 and 51.

A machine comprising: a flexible band (1) unwinding unit (11), a flexible band (1) folding unit (14), a drive unit (31) for moving the flexible band (1) in a forward movement direction (DA), a welding unit (16) and a laser beam cutting unit (53) for separating each individual flexible package from the flexible band (1) and for providing a fill opening in each flexible package by at least one fill opening cut, the laser beam cutting unit (53) having associated therewith a separator device, movable in a vertical direction and including an insertable separator element (41), interposed between the opposite faces of the folded flexible band (1), in an area adjacent to the fill opening (3), for separating the opposite faces of the flexible band (1) during cutting operations to prevent the fusion thereof.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

Methods of making a woven laminated plastic bag having an easy open feature are provided. The easy open feature is generally defined by a weakened portion in the bag, such as formed by cutting, punching, or using a laser to provide a plurality of cuts and/or perforations in the bag. In various aspects the bag can be fabricated from a woven polypropylene and/or polyethylene layer, which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also be sealed to be sealed to provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

The present invention provides a disposable bioprocess bag, a manufacturing method therefor and a hot-melt annular welding machine, relating to the technical field of biopharmaceutics. The manufacturing method comprises: preparing a first cropping template to a fourth cropping template according to a top, an upper portion, a lower portion and a bottom of a bioreactor; cropping a raw material film according to the first cropping template to the fourth cropping template to obtain a first membrane material to a fourth membrane material, wherein the fourth membrane material directly serves as a rounded bottom; welding at least two pockets on the first membrane material to obtain a rounded top; welding the second membrane material to obtain a cylindrical upper portion; welding the third membrane material to obtain a lower portion in the shape of an inverted rounded truncated cone; and welding, using a hot-melt annular welding machine, the rounded top, the cylindrical upper part, the lower portion in the shape of an inverted rounded truncated cone and the rounded bottom, to obtain a disposable bioprocess bag. According to the present invention, the physical properties of the welded edge of the disposable bioprocess bag are improved, and the fit of the disposable bioprocess bag to the bioreactor are also enhanced.

A film roll on which a tube film is wound is supported by a lower shelf of a frame. The tube film is fed from a reel mechanism. A table for guiding the fed tube film is provided in the upper part of the apparatus. The tube film held by a clip mechanism on the table is drawn to the front end of the table, and the drawn tube film is cut into a predetermined length while being pressed by a press cutter. The clip mechanism is provided with a clip including a pair of fingers for holding the tube film. The clip mechanism is provided on a slide mechanism for reciprocating the clip.
