An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.

The invention relates to a packaged product or group of products, such as a candy, wherein said product or group of products has an elongated form, wherein the package comprises at least one film which encloses said product or group of products, and wherein part of said film extends from at least one outer end of the product or group of products, and wherein said part of the film is bent away from the direction of the axis of the elongated product or group of products back towards a part of the film that surrounds the product and is bonded therewith. The invention also relates to an easy opening arrangement for packaged products, and to an array or bandoleer of products with reduced packaging material.

An absorbent article includes a novel design printing portion suitable for a stretchable region. An absorbent article has an elastic film stretchable structure, in which an elastic film is stacked between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded together directly or through the elastic film by a large number of sheet bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region. The stretchable region is contracted in a stretchable direction by a contraction force of the elastic film is extensible in the stretchable direction. A design printing portion is provided in a portion located in the stretchable region in the elastic film.

A rotary impulse sealer for forming a series of discrete bonds in a bondable material. The rotary impulse sealer has a roller rotatable about an axis. The roller has a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, the regions being stationary with respect to the rotation of the roller. A method of forming packages containing fluid or fluent material includes continuously providing at least two sheets of bondable material having a fluid or fluent material therebetween, applying pressure to a transverse bond area of the bondable material to force the fluid or fluent material away from the transverse bond area, and heating the transverse bond area to form a seal.

A method and apparatus for making bags from a film that follows a film path through a bag machine includes an input section located on the film path, a sealing section located on the film path downstream of the input section, an output section located on the film path downstream of the sealing section, and a controller, connected to control the sealing section. The sealing section includes a sealer that includes a heater block and a manifold. There is an air flow path from the heater block to the manifold. Air is heated in the heater block in response to a control signal provided by the controller to the heater block. The heated air is provided through the air path to the manifold. A temperature sensor is disposed in at least one of the air path and the manifold.
