摘要:
A method and an apparatus for making pouches is disclosed. The apparatus comprises an infeed section, disposed to receive a laminate film; a sealing section, disposed to receive the laminate film from the infeed section, including a sealing platen, further including at least one servo motor connected to move the sealing platen to intermittently contact the laminate film, wherein the at least one servo motor has a control input and a feedback output, wherein the sealing section further includes at least one driven roll to move the laminate film through the sealing section; an outfeed section, disposed to receive the laminate film from the sealing section; and a controller, connected to receive feedback from the feedback output, and having a control output responsive to the feedback and connected to the control input, wherein the controller includes a calibration module connected to the control output and the feedback output.

A package comprises a heat seal between a first film and a second film. The first film comprises at least 70% of one or more polyamides. The first film also comprises at least one modified layer comprising (1) at least 70% of one or more polyamides and (2) one or more modifiers selected from ethylene/alkyl(meth)acrylate copolymers, ethylene/(meth)acrylic acid copolymers, and ionomers. The second film comprises at least 70%) of one or more polyamides. The package is useful under ovenable conditions.

Pouch machine includes infeed section, sealing section, outfeed section. Sealing section Includes at least one sealer that has a sealing fixture disposed to move in a first direction toward and away from a sealing position. A linear actuator provides a controlled motion in a second direction, not the first direction. A linkage is connected between the linear actuator and the sealing fixture. The linkage translates the motion of the actuator into controlled motion of the sealer. The linkage multiplies force when the sealer is in the sealing position, and multiplies distance/velocity when the sealer is retracted. Sealing fixture includes a die backing having at least one clip mounted on it. The clip includes a hook end, a first relaxed position and second tension position. Sealing die includes a receiver that receives the hook end. When the clip is in the tension position, sealing die is held against die backing member.

A heat sealing method of a zipper tape (3) is for heat sealing the zipper tape (3) in a direction perpendicular to a feeding direction of a film (21). The heat sealing method includes: inserting the zipper tape (3) between the film (21) and a circumference of a roller (4) on which the film (21) is wound; and heat sealing the zipper tape (3) to the film (21) with a seal bar (5) following a rotation of the roller (4) in a continuous manner, while the zipper tape (3) is interposed between the circumference of the roller (4) and the film (21).
摘要:
In a method for closing a tubular sack body made from a woven fabric of monoaxially drawn polymer, in particular polyolefin or polypropylene, ribbons, comprising the production of a bottom fold in such a way that the sack has a substantially rectangular bottom, at least two layers of the bottom which overlap one another at least partially are welded to one another in the region of their overlap by way of at least one welded seam in order to close the bottom, wherein the at least one welded seam extends at least over the length of the broad side and/or the narrow side of the rectangular bottom.
