An apparatus for packaging a product comprises a packaging assembly to fix a film sheet to a support. The packaging assembly includes a lower tool having seats for receiving the support and an upper tool facing the lower tool and comprising a film holding plate for holding the film sheet. The film holding plate has an active surface for receiving the film sheet, where the upper and lower tools cooperating to define a packaging chamber. The packaging assembly is open to receive the film sheet in a first operating condition and is hermetically closed in a second operating condition. The film holding plate has a lateral surface extending substantially perpendicular to a plane defined by the active surface, the film holding plate comprising ejectors arranged in the lateral surface for ejecting a stream of gas substantially parallel to said plane and substantially away from a center of the active surface.

The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanurate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.

A shaker top for dispensing products in a container, including a top unit having a peelable protective cover affixed by heat staking upon a dispensing liner having at least one perforation, the top unit affixed to a mouth of a container. A method of manufacturing a shaker top with a peelable protective cover, including the steps of affixing a peelable protective cover upon a dispensing liner by heat staking, assembling a top unit including the peelable protective cover and the dispensing liner, affixing the top unit to a mouth of a container, and covering the container with a cap. A shaker top with a peelable protective cover attached to a container, manufactured by the method of manufacture. A method of using a container having a shaker top with a freshness seal.

A device for liquid-tight sealing of two partially overlapping packaging components. One of these is a tubular basic body. A further packaging component forms the packaging head or bottom, having at least one mandrel and one die. For the tubular basic body to be easily slid on to the mandrel and removed the expansion elements have sealing jaws which, in their working position, form a closed, encircling outer contour.

A vertical form fill and seal system supports a sheet of material having material segments and a tube sized for drawing edges of the elongated sheet of material together in an overlapping configuration to form the sheet into a substantially tube shape. The VFFS also includes a sealer that seals the edges of the material to one another and a gusseting mechanism sized for forming a gusseted tuck in each of a left panel portion of the material and a right panel portion of the material. A cutting mechanism removes a first portion and a second portion of a first segment of the material segments in order to form a first cut and a second cut in the first segment and a sealing mechanism folds and seals the first segment at the first cut and at the second cut to provide an end wall with a substantially flat, rectangular-shaped footprint.

An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.

The present invention relates to an induction sealing device for heat sealing of packaging material. The sealing device comprises a conductor partly encapsulated in a supporting body for cooperation with the packaging material during sealing. The coil conductor has a reduced cross sectional area at at least one position along the coil conductor so as to concentrate the magnetic flux induced by the coil conductor at the at least one position. The invention also relates to a method of heat sealing a packaging material using the induction sealing device.

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 and apparatus for making pouches is disclosed. It includes using one or more of the following features: using two servo motors to drive a platen, providing a calibration routine is run at start-up and/or after the machine has been operating; controlling in response to feed back from the servo motor(s) such as feedback indicative of the distance the platen travels; the feedback is not of force exerted by the platen; and/or the platen is controlled to prevent unacceptable fracturing of the film laminate.

An ultrasonic sealing apparatus for paper packages achieves more stable ultrasonic sealing by cooling the horn during ultrasonic sealing which would otherwise be unstable due to heat imparted to a horn by continuous sealing. An end portion of a horn of a casing that includes the horn and a converter, or the horn, a booster and the converter is cooled by supplying air to a frame portion exposed toward an anvil side.
