The present invention provides a food packaging machine comprising a packaging material supply module, a food supply module, a filling module. The food packaging machine further comprises a hardware data processor operably connected to the packaging material supply module, operably connected to the food supply module, so operable to create a food data transaction, and operably connected to a network data processing system. The hardware data processor is operable to send the food data transaction to the network data processing system for the data transaction to be appended to a packaged food production data hash tree. The present invention further provides a system for packaging food comprising a plurality of food packaging machines as well as methods for tracking food data transactions in a food packaging machine and in a system for packaging food.

The present invention concerns a device (1) for applying gripping handles (M) on films (P), being supplied on shrinkwrap packers (2) for making bundles of bottles (B), cans and/or similar containers (B). The device (1) comprises: an applying head (10) provided with a roller (11) for applying gripping handles (M); an abutment mechanism (14) for operatively supporting a series of heat-shrinkable packaging films (P), being supplied on a respective shrinkwrap packer (2). The applying roller (11) and the abutment mechanism (14) are mobile with respect to one another between a non-operating condition, in which they are spaced apart, and an operating condition, in which the applying roller (11) is arranged, at the abutment mechanism (14), against at least one of the films (P) being supplied to apply a respective gripping handle (M) on the latter. The abutment mechanism (14) comprises a supporting tape (15) having an advancement surface (16) for advancing the films (P), which, in the operating condition, provides an abutment for the applying roller (11), which applies each handle (M) on a respective packaging film (P), acting against the advancement surface (16) of the supporting tape (15).

The invention relates to shrink packaging for packing a series of containers. The packaging is characterized in that at least one incision line is provided in a first zone, said incision line including a series of perforations forming at least one partially detachable section arranged to allow the extraction of at least one container in a direction extending substantially from the lower part of the container to the upper part thereof, said partially detachable packaging section being larger than the cross-section of the at least one container to be extracted. Moreover, the partially detachable section is located on the periphery of the first zone.

A film wrapping machine has a film leading device having a fixed frame, a shaft, a film-leading component, a torsion spring, a positioning block, and a positioning pin. The shaft is rotatably disposed on the fixed frame; the film-leading component is fixed on the shaft and has a frame body, a film-holding board disposed on the frame body, and a limiting element. The positioning block has a pin groove, and the positioning block and the positioning pin are respectively disposed on the fixed frame and the frame body. When unlocking, the positioning pin is detached from the pin groove, and the torsion spring actuates the film-leading component and the shaft to rotate relative to the fixed frame. When repositioning, the film-leading component is pushed to allow the positioning pin to be reinserted into the pin groove.

Provided is a sheet material end detection mechanism including: a sheet material information part indicating information on a sheet material wound around a core member in which a through hole is formed; a reader configured to optically read the sheet material information part; and a detection unit configured to detect that the sheet material is used up. The sheet material information part extends from a portion corresponding to the through hole at an end of the sheet material wound around the core member to a portion adjacent to the through hole on an inner surface of the core member. The detection unit detects that the sheet material is present when a read signal of the sheet material information part read by the reader is received and that the sheet material is used up when the read signal disappears.
