Abstract

Described is a method for making openable packages for a food product in liquid or pasty form comprising the steps of: feeding a continuous film (1); cutting the continuous film (1) to form a plurality of single sheets (2) and forming on each single sheet (2) crease lines designed to define fold lines for forming a container; preparing an element (3) rotating about an axis (3X) of rotation and equipped with a plurality of forming mandrels along its circumference; coupling the single sheet (2) to a forming mandrel (4) in a first predetermined angular position of rotation of the forming mandrel (4); folding the single sheet (2) around the forming mandrel (4) using folding devices (5-8) configured to wrap the single sheet (2) on the forming mandrel (4), folding it along the crease lines, in such a way as to create a bottom (2f) and front walls (2a, 2B) and side walls (2c, 2d) when the sheet is coupled with the forming mandrel (4); performing a partial sealing of the single sheet (2) folded on the forming mandrel (4), in such a way as to obtain a container open only on an end side, positioned opposite the closed bottom (2f), with an opening (2e) for access to an inner cavity; transferring the open and partly sealed container from the forming mandrel (4) to a conveyor device (9); filling with the food product the cavity of the open container through the access opening (2e), and, upon completion the filling, completely closing the container by final sealing of the access opening (2e), in such a way as to make a sealed openable container.
