The present invention can combine fabrics in a seamless manner by forming at least one bonding pattern line by a process comprising: printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, and/or an outer fabric or an optional mesh material in a predetermined pattern, laminating said inner fabric, optional reinforced material and outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, and outer fabric.

Since the present invention combines fabrics by employing a high-frequency bonding manner in which a heat-reactive adhesive is used, it is possible to combine fabrics in a seamless manner with a bonding pattern line which is composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with a good clearness and finishing quality.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

The invention relates to a cross seam joining device for a flexible packaging having at least one ultrasonic applicator (13a-13c), which is rotatably mounted on a shaft (13d) and can be rotated about an axis (13e) of the shaft (13d) arranged longitudinally to the cross seam (110, 111). The ultrasonic applicator (13a-13c) is designed to produce and bundle ultrasounds in a frequency range of 0.1 MHz-0.5 MHz, preferably from 0.5 MHz-2 MHz.

The invention relates to a method for joining a sealing seam of a tubular bag packaging by means of an ultrasonic applicator (10), characterized in that said ultrasonic applicator (10) generates ultrasonic waves at a frequency of between 0.1 MHz and 5 MHz, preferably between 0.5 MHz and 2 MHz. The invention also relates to a longitudinal seal joining device of a tubular bag machine for use with said claimed method.

The present disclosure relates to an oral pouched snuff product and a method for its production. The oral pouched snuff product comprises a filling material and a saliva-permeable pouch enclosing the filling material, the saliva-permeable pouch comprising at least one elongated seal and the saliva-permeable pouch comprising a mesh material being elastic in at least one direction and comprising fibres of thermoplastic polyamide, wherein the at least one elongated seal has a seal strength of at least 0.10 N/mm as measured in dry state as well as in wet state. The at least one elongated seal may be an ultrasonically provided weld.

A multi-layer thermoplastic film include a first film of thermoplastic material, a second film of thermoplastic material bonded to the first film, and an odor control component disposed between the first film and the second film. A method of manufacturing a multi-layer thermoplastic film coextruding a plurality of layers to form a first film, coextruding a plurality of layers to form a second film, disposing at least one odor control component on at least one of the first film and the second film, and bonding the first and second films together such that the at least one substance is disposed between the first film and the second film.

A packaging assembly (10) that includes a weighing machine (11) that delivers batches of product to a packaging machine (18). A film drive assembly (17) pulls strip bag material pass a former shoulder (41), to form tubular bag material into which batches of product are to be delivered, with the tubular bag material being longitudinally sealed, transversely sealed and transversely cut by the packaging machine (18).
