Provided is a film thermoforming device of a blister packaging machine in which molding can be carried out without extreme reduction in a sheet thickness of a top surface portion of a pocket, and without warpage, which allows stacking, and stable molding can be performed at a high rate. This film thermoforming device comprises a compressed air blowing mechanism that is disposed at a forming mold 5A and that has a compressed air blowing pore 53a which is open at an inner bottom portion of a pocket hole 52 of the forming mold 5A, and a compressed air blowing pore 53b which is open around the pocket hole 52 of the forming mold 5A.

A blister packing machine includes: a conveyor that conveys a belt-like container film having a pocket portion forming area and an expected mounting part; a preheating device that preheats the container film conveyed by the conveyor; a pocket portion forming device that forms a pocket portion in the container film softened by the preheating device; and a tension applier that applies a tension along a width direction of the container film to at least the pocket portion forming area. The pocket portion forming device forms the pocket portion while the tension applier applies the tension to the container film, the container film has an edge area between an edge in the width direction and the expected mounting part, and the tension applier includes a projection that applies the tension to the container film by pressing the edge area to form a protruding portion in the container film.

A method for producing filled containers (16) from preforms (13). Each of the preforms is transferred to a circulating molding and filling element (14) of a molding and filling station and is shaped into the respective container in a subsequent molding and filling process in a mold under the effect of pressure from a supplied filler, wherein the mold is designed in multiple parts, including a base mold (21) and mold sides (19, 20), and each container is clamped between the base mold at the bottom and the molding and filling element at the top at least at the end of the molding and filling process. The container is separated from the respective molding and filling element and the respective mold after the molding and filling process. The mold sides are removed from each container before the molding and filling element and the base mold are separated from the container.

A forming station for producing a packaging trough by thermoforming at least an area of a film web positioned between a forming tool upper part and a forming tool lower part of the forming station. A male die part of the forming tool upper part may be moved in a vertical direction and inserted into a forming space of a female die part of the forming tool lower part. The packaging trough is produced by deforming the film web between the male die part and an inner wall of the forming space of the female die part. In an inserted condition of the male die part within the female die art, a push-in unit is extended from the male die part towards the inner wall of the forming space at an angular orientation relative to the vertical direction.

An inflatable web is disclosed. The web includes first and second film plies sealed together via a plurality of generally transverse seals to define a first and second inflatable chambers and an inflation region. The chambers are inflatable with a fluid and operable to contain the fluid. The sealed plies have a first longitudinal edge and a second longitudinal edge. The web defines a separation region extending at least partially transversely across the web between the first and second inflatable chambers and is configured to facilitate separation thereof. The separation region includes a tear propagation line extending transversely across at least a portion of the web with an end of the tear propagation line terminating proximal to the first longitudinal edge of the web. The separation region includes a tear initiation feature including edges spaced apart from one another longitudinally to form a permanent opening in the web.
