A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

Impulse heat sealing of a heat-sealable film material

A spout () having a plastic spout body which comprises an attachment portion () having a vertical first plane of symmetry (M) with a vertical first sealing wall () and an opposed vertical second sealing wall (), and with a transverse wall (), which is integrally connected to an upper edge of the first sealing wall and to an upper edge of the second sealing wall, wherein the first sealing wall and the second sealing wall each depend from said transverse wall and each have a bottom edge () remote from the upper edge. Each sealing wall is, seen in a bottom view of the attachment portion, composed of a first rectilinear portion (), a central curved portion (), and a second rectilinear portion (). The spout body has a tubular neck () having a bore () that adjoins an opening () in the transverse wall. The attachment portion further comprises curved stabilizing ribs () extending between associated connection points to the opposed rectilinear portions of the sealing walls.

Plastic spout and pouch packaging

A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

Continuous motion impulse heat sealing of film material

A production machine for the production of collapsible pouches having a fitment. The machine has a fitment sealing station with an impulse sealing device comprising a first jaw and a second jaw and with an actuator device configured to move the first and second jaws relative to one another between an opened position and a clamped position, as well as a cooling device configured to cool each of the first and second jaws. The fitment sealing station is configured to perform an impulse sealing cycle.

Production of collapsible pouches having a fitment

The present invention relates to a production machine for the production of collapsible pouches, which comprises an impulse sealing device with a first jaw and a second jaw for contacting bottom regions of walls of the pouches. Each jaw comprises a susceptor element comprising electrically conductive material, having a front surface that is at least shaped as an inverted T for sealing side edges and at least a portion of bottom edges of two adjacent interconnected pouches. Each jaw comprises an inductor which is electrically insulated from the respective susceptor element. The machine comprises a high frequency electric current source, which is connected to the inductors. At least one of the jaws comprises a cooling device for cooling down the respective inductor and susceptor element. The machine is configured so that, in an impulse sealing cycle for sealing the bottom regions of the pouch walls, the electric current source is operated to temporarily feed a high frequency electric current to the inductors, thereby generating a high frequency electromagnetic field with the inductors. The high frequency electromagnetic field induces eddy currents in the respective susceptor element generating an impulse of heat that is emitted by the susceptor element, which impulses of heat seal the bottom regions of the pouch walls to each other.
