Abstract: A packaging machine device includes at least one closure device (10), in particular a sealing device, for producing at least one closure seam (12, 14), in particular a sealing seam, on at least one packaging material (16), and includes a forming device (18) configured to form the packaging material (16), which has been pre-formed into a tubular bag, in a region of the closure seam (12, 14), in particular at least partly before a production of the closure seam (12, 14). The forming device (18) is configured to form the packaging material (16) in the region of the closure seam (12, 14), starting from an inner region (24) of the closure seam (12, 14) in a direction (30, 32) towards at least one outer region (26, 28) of the closure seam (12, 14).

Abstract: The invention is based on a primary packaging, in particular a primary paper packaging, for receiving at least one product (12), in particular a food product, with at least one enveloping unit (14), which in particular comes into contact with the product (12) directly, in particular a tubular bag; the enveloping unit (14), in particular the tubular bag, comprising at least one barrier layer (16) for a protection of the received product (12), in particular from humidity, and comprising at least one carrier layer (18), in particular paper layer, which is connected with the barrier layer (16), in particular by substance-to-substance bond. It is proposed that the primary packaging comprises at least one functional unit (20), which is in particular embodied in a one-part implementation with the enveloping unit (14), for a protection of the enveloping unit (14) and/or of the received product (12) from damages.
