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.

An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.

A packaging system for film including: a controller; and a seal jaw controlled by the controller, wherein the seal jaw includes: a first sealing bar; a second sealing bar; a servo motor controlling movement of at least one of the first and the second sealing bars between an open position and a closed position, where the sealing bars are in contact; and a pneumatic cylinder, connected with at least one of the first and second sealing bars, and controlling a pressure between the sealing bars when in the closed position. A method of creating a seal in packaging film, the method including: moving, via a servo motor, a first sealing bar and a second sealing bar from an open position to a closed position; and upon reaching the closed position, clamping, via a pneumatic cylinder, the sealing bars to create a seal in the packaging film.

A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a pair of spaced apart heating elements positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating elements is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating elements increase a temperature at the interface to melt the plastic material and form a pair of spaced apart seals between the first and second plastic layers.

A human tissue isolation pouch for use with a sealer machine to indirectly seal human tissue medical pouches while avoiding cross contamination is herein disclosed. The human tissue isolation pouch comprises a rigid frame supporting a high temperature material and having one or more magnets for removably attaching the human tissue isolation pouch to a sealer machine. During use a medical pouch, which may contain a human tissue sample, is inserted within the human tissue isolation pouch. The jaws of the sealer machine clamp down directly on the high temperature material, thus indirectly heating and sealing the medical pouch inside the human tissue isolation pouch. The sealing machine jaws do not physically contact the medical pouch at any time during the sealing process, and in this way contamination of the sealer machine (and cross contamination of medical pouches from distinct donor cases) is avoided. The rigid frame of the human tissue isolation pouch may be sterilized after each donor event. And the containment bag formed of a high temperature material may be disposed of after each donor event.

The present invention relates to a band-like joint tape for covering a butting portion formed by butting an end portion of a one packing film to an end portion of another packing film and connecting the respective end portions of these packing films to each other. The joint tape is comprised of a laminate film formed by adhering a joint layer to a support layer at a peelable state, and covered so as to face the joint portion. to the butting portion and heat-sealed so that the joint layer is fused to the butting portion and the fused portion of the joint layer is peeled off from the support layer.

A method attaches a liquid-repellent filter to an air vent of a resin molded article accommodating a component/electronic part. A thermal processing tip and a thermally welding tip and a molded article are provided. The thermal processing tip (22) forms a filter attachment surface (14) at the inlet or outlet of an air vent (16) in a thermoplastic resin molded article (13). A filter fixing rib (15) is formed around the attachment surface. The porous filter (18) is dropped onto the filter attachment surface, and a thermal welding tip (2) is used to melt the filter fixing rib such that the melted resin flows onto and covers a circumferential edge portion of the filter, penetrating the body of the filter. The melted resin penetrating the filter 18 and covering the circumferential edge portion of the filter are cooled to solid, whereby the filter is fixed to the filter attachment surface.
