The invention relates to a sealing body, where heat-producing elements of a heating element are contacted from the rear side thereof. Other aspects relate to a sealing body where the site of the heat production and the site of the heat dissipation (i.e. the point of action) are as close to each other as possible. Other aspects relate to a sealing body comprising a heat element with a built-in temperature sensor. Other aspects relate to a sealing body with a defined sealing contour. Other aspects relate to a sealing body having a three-dimensionally structured contact surface. Other aspects relate to a sealing body with a circular, annular, or strip-type heat element. Other aspects relate to a sealing body with built-in electronic circuits. Other aspects relate to a sealing body that can cool the heating element as required. Other aspects relate to a sealing body that can suck up the material to be welded.

The present invention relates to a sealing band for a sealing jaw arrangement, comprising a contact surface and an opposite bottom surface, a first portion adjacent to the contact surface and a second portion adjacent to the bottom surface. The portions are separated by a waist, and said sealing band is symmetrical along a first axis that extends perpendicularly from a middle of the bottom surface, and the waist between the first portion and the second portion is located closer to the contact surface than to the bottom surface. The invention also relates to a counter jaw for holding the sealing band, and to a sealing jaw arrangement comprising such a counter jaw and a heating jaw.

There is described a unit for applying at least one pre-formed opening device onto a hole of a web of a packaging material, unit comprises an advancing means device for advancing the web along a path; and at least one application station, which is fed, in use, with pre-formed opening device and seals, in use, pre-formed opening device on the hole of web.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. A folded insert disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

A method of manufacturing a heat exchanger array that includes stacking a plurality of heat exchanger units in an aligned configuration with respective first ports of the plurality of heat exchanger units aligned. The method can further include generating heat in the first coupling elements at the same time and at a temperature sufficient to generate a first plurality of respective couplings between adjacent sheets of adjacent heat exchanger units about adjacent first ports and without a coupling being generated between the first and second sheets of a given heat exchanger unit.

A description is given of a method for joining a first and a second film web (2, 2′) of a transfer film or laminating film, wherein the film webs (2, 2′) comprise a thermoplastic carrier film (21) and a decorative layer (23). Formed between the first and second film webs (2, 2′) is a common joining portion (3), in which the first and second film webs (2, 2′) are joined to each other by a welding process. A device for carrying out the method is also described.

A method and apparatus for pleating or otherwise shaping a web are described herein. The method and apparatus may have numerous applications. In some embodiments, the method and apparatus are used in the formation, filling, and sealing of unit dose packages for consumer products. A method and apparatus for forming sealing two moving webs together, which webs have portions that are non-planar are also described herein.

Disclosed embodiments relate to an induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products. In some embodiments, the sealing device includes: an inductor device which interacts with said packaging material by means of at least one active surface; a flux-concentrating insert; and a supporting body made of heat-conducting material and housing said inductor device and said flux-concentrating insert, wherein said flux concentrating insert is made by a magnetic compound of a polymer and soft magnetic particles; and said flux concentrating insert interacts with said packaging material via at least one interactive surface.

A method for the production and filling of an application package for a liquid pharmaceutical product. A thermoforming film made of thermoplastics laminated together is heated in order to plasticize the thermoforming film at least in partial areas. The plasticized areas are thermoformed in a mold in order to form a chamber for the liquid pharmaceutical product and a tube-shaped application duct opening into this chamber, with the chamber and the application duct being enclosed by a non-thermoformed, essentially flat bonding area of the thermoforming film. The liquid pharmaceutical product is filled into the chamber, and the chamber and the application duct are sealed by covering the thermoformed and filled thermoforming film with an essentially flat covering film. The covering film is directly bonded to the bonding area of the thermoforming film by thermal ring sealing, enclosing the chamber and the application duct.

A sealing element for heat sealing packaging material for producing sealed packages comprises a heating element arranged to heat-seal the packaging material so as to form the sealed packages and a groove arranged to be engaged by a cutting element carried by a counter-sealing element interacting with the sealing element during a cutting operation in which a sealed package is separated from a portion of the packaging material, wherein the sealing element further comprises a resilient element received within the groove so as to prevent clogging particles from entering into the groove.
