A sealing mechanism for a waste storage container includes a waste storage container that has a body, a lid and a cartridge adapted to be positioned in the body. The cartridge has a continuous length of storage film therein. The storage film emanates through a gap between a rim and a core tube of the cartridge and is folded down through a core opening in the core tube into an interior space of the body of the waste storage container. The sealing mechanism includes an actuator accessible from outside the body, a gear assembly operably connected to the actuator, a retaining assembly that holds stationary a dispensed portion of the storage film in the interior space of the body during a twist-closure operation, and a plunger operably connected to the gear assembly

The present invention relates to a device for manufacturing a pouch containing a brewable material accommodated in a wrapping, comprising a pouch manufacturing device adapted to manufacture a water-permeable pouch containing brewable material, and comprising a sealing station with two sealing jaws movable relative to one another for sealing the pouch in the wrapping placed in a U-shape around the pouch, wherein the sealing jaws are configured to form longitudinal seals (L) lying opposite one another and a transverse seal (Q) extending transversely thereto on the wrapping, wherein at least one sealing jaw comprises first and second sealing jaw elements each configured to form one of the longitudinal seals (L) and a segment of the transverse seal (Q).

The present invention relates to a vacuum cleaner filter bag made of a thermally weldable filter material which forms the sealed internal space of the vacuum cleaner filter bag. The internal space is thereby closed at least on one side by means of a weld seam configured according to the invention, in the case of which at least two layers of the filter material are welded together. The weld seam configured according to the present invention is distinguished by a far higher tearing strength, compared with weld seams as are known from the state of the art. The invention relates in addition to a method for the production of the vacuum cleaner filter bag, to a tool for the production of the high-strength weld seam and also to an ultrasonic welding unit in which this tool is integrated.

The present disclosure is directed to dunnage bags formed using polyethylene terephthalate (PET) and processes for manufacturing these PET dunnage bags. Generally, the PET dunnage bags of the present disclosure include a PET outer bag, an inner bladder enclosed within the PET outer bag, and a valve assembly that enables air to be introduced into (or escape out of) the inner bladder to inflate (or deflate) the inner bladder, thereby inflating (or deflating) the PET dunnage bag.

A method and apparatus for sealing a bag made of a polymeric material by applying heat activated layers on different portions of the bag, wherein the first adhesive layer and the second adhesive layer have respective heat activation temperatures below the softening point temperature of the polymeric material; after creasing the bag along a fold line, applying heat at a temperature below the softening point temperature of the polymeric material to activate the first adhesive layer and the second adhesive layer to adhesive states after the bag has been filled with contents; and folding the bag to form an adhesive-to adhesive seal by contact between the heat activated first adhesive layer and the heat activated second adhesive layer.

A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

There is provided a moisture-sensitive vacuum packing machine, and particularly, there is provided a moisture-sensitive vacuum packing machine for sensing moisture within a chamber. The moisture-sensitive vacuum packing machine includes: a device housing having a controller and a vacuum driving unit; a chamber unit positioned above the device housing and having a first chamber and a second chamber whose interiors are vacuumized when the vacuum driving unit operates; and a sensing unit installed in the chamber unit such that it is associated with the controller, and sensing the presence or absence of moisture within the second chamber according to whether the sensing unit comes into contact with the second chamber.

A composite belt assembly for a band sealer is provided. The composite belt assembly comprises a belt comprising a main belt; a first layer; and a second layer; wherein the first layer is arranged in contact with the main belt, preferably between the second layer and the main belt; and the first layer includes an attachment portion, configured to contact the main belt and the second layer. There is also provided a band sealer comprising a composite belt assembly and a packaging line comprising the band sealer. There is further provided a method for heat sealing a package, comprising providing a composite belt assembly, gripping a bag neck of the package using the composite belt assembly, guiding the bag neck of the package along a movement plane using the composite belt assembly providing a sealing element configured for heat sealing a plastic material of the bag neck, and applying heat to at least part of the bag neck through the first layer of the composite belt assembly using the sealing element.
