A method of producing packages from a tube of packaging material for a liquid food product, comprises reforming a flat web of packaging material into a cylindrical tube, feeding the tube of packaging material in first direction, filling the tube with a liquid food product, transversally sealing the tube, at regular intervals, into separate package volumes, wherein a longitudinal axis of every second transversal seal being parallel to each other, and a longitudinal axis of each adjacent transversal seal being perpendicular to each other, and wherein a longitudinal axis of each transversal seal is angled in a range between 15-30 in relation to a plane which is orthogonal to the longitudinal axis of the tube of packaging material. Also disclosed is a packaging material for use in the method, a package produced with the method, and a filling machine performing the method.

A bottom and side gusseted package comprises a package body, a pair of inwardly extending side gussets, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the inwardly extending side gussets are formed, and the flexible web is cut to form individual packages, such that each individual sleeve forms a bottom gusset in a respective one of the gusseted packages.

The present invention discloses a flat bottom pillow pouch that can stand upright on its bottom transverse seal. The flat bottom pillow bag can be made from the same film as a standard pillow pouch and requires less film than prior art stand up packages. The flat bottom pillow pouch disclosed herein has no gussets.

An assembly for producing sealed packaging units (14) from a sheet packaging material, comprises: an advancement device (21) for advancing the sheet packaging material along an advancement direction (F), a longitudinal sealing device for sealing opposite borders of the sheet packaging material along a longitudinal sealing band arranged parallelly to the advancement direction (F), thereby forming a continuous tube (15), a transverse sealing device (29) for sealing the continuous tube (15) transversely to the advancement direction (F), so as to define a sealed packaging unit (14). The transverse sealing device (29) comprises a sealing element (30) and an abutment element (31) that are intended to mutually cooperate during sealing while being located on opposite sides of the continuous tube (15). The sealing element (30) is so configured as to act on a side (27) of the continuous tube (15) on which the longitudinal sealing band is provided.

A bag-making and packaging apparatus creates one product per cycle by packaging articles in a bag made from a film. The bag-making and packaging apparatus includes a longitudinal sealing mechanism, a guide, an article sensor, a transverse sealing mechanism, a cutting mechanism, and a prediction unit. The guide guides the articles which fall from above into a film tube. The transverse sealing mechanism forms a transversely sealed part in the film tube with each cycle. The cutting mechanism cuts the film tube in the transversely sealed part with each cycle. The prediction unit predicts whether or not jamming of the articles could occur in the transverse sealing mechanism on the basis of an output of the article sensor with each cycle. When the prediction unit has predicted that the jamming could occur in a certain cycle, the cutting mechanism does not cut the film tube in the certain cycle.
