A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

The present invention relates to a cassette module for controlling fluid flows, in particular for use in blood treatment systems or in infusion systems, wherein the cassette module comprises at least one base body having means for the flow guidance of at least one fluid flow and at least two membranes which are at least sectionally directly or indirectly in contact with the base body, wherein at least one actuation element is arranged between the membranes by means of which the means for the flow guidance can be acted on.

A system for coinjection molding a multi-layer container includes an injection molding apparatus, a camera, and a controller. The injection molding apparatus is configured to coinject a plurality of polymeric materials into a mold cavity to form a multi-layer container including an inner layer, an outer layer, and a barrier layer located between the inner layer and the outer layer. The camera is configured to capture an image indicating a location of the barrier layer within the multi-layer container. The controller is configured to monitor the location of the barrier layer using the image captured by the camera, compare the location of the barrier layer to a threshold location, and provide a control signal to the injection molding apparatus based on the location of the barrier layer relative to the threshold location.

A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

An extensible bearing element of a tool for sealing a bottom or a lid of a cardboard package on a body of said package has a generally polygonal shape and a cross-sectional profile. The bearing element is formed by two parallel extension sections extending along an extension direction, each connected, at one of their ends, to a bearing section. The extension sections and the bearing section define an inflation cavity. The extension sections are configured to extend along the extension direction when the bearing element is inflated. The bearing section comprises a substantially flat, free bearing surface that contacts the package body. The bearing surface extends along a plane substantially normal to the extension direction. The bearing section further comprises, at the junctions with the extension sections, beveled release portions. An inflation device comprising such an extensible bearing element is also described.

A device comprising a first fixing element, a further fixing element, and a folded planar composite is disclosed. The first fixing element comprises a first fixing surface and the further fixing element comprises a further fixing surface. The folded planar composite is at least partially fixed between the first fixing surface and the further fixing surface. The folded planar composite comprises a first composite region and a further composite region.

A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.

There is described a packaging assembly configured to form and seal a plurality of packs for containing a pourable food product starting from a tube of packaging material; the packaging assembly comprises a pair of tracks and at least a pair of moving elements, which are cyclically movable along the tracks, respectively; each moving element comprises one forming unit configured to cooperate with the tube so as to surround a portion of the tube destined to form a main portion of one respective pack; and one sealing unit configured to cooperate with the tube to sequentially seal the tube at predetermined consecutive cross sections, each pair of consecutive cross sections forming opposite sealing bands of one respective pack; each forming unit is mounted onto the respective moving element in a linearly movable manner towards and away from the sealing unit mounted onto the same moving element.

An anvil for transversally sealing a tube having a longitudinal seam portion can include a first elongate contact surface and a second elongate contact surface. In some embodiments, the first elongate contact surface includes a first groove and the second elongate contact surface includes a second groove, each one of the first groove and the second groove being adapted to receive, in use, a respective section of the longitudinal seam portion of the tube. The first elongate contact surface can include a first seam interaction portion positioned within the first groove and having a first surface profile. The second elongate contact surface can include a second seam interaction portion positioned within the second groove and having a second surface profile. In some embodiments, the first surface profile differs from the second surface profile.
