摘要： An apparatus is configured to make containers from sheet material. The apparatus includes a supply station for supplying a film having at least one folded portion having three or more film flaps folded and superimposed with respect to each other; a welding station configured to receive the film. The welding station comprises a welding head configured for welding the folded portion of the film and forming a container defining a housing compartment; the welding head comprises a heater made of electrically conductive material whose electrical resistivity, at least in a predetermined temperature range, decreases upon the increase of the temperature of the same electrically conductive material.

摘要： The present invention relates to a package for containing a product comprising a support (1) which has: a base (2) configured for receiving one or more products, a perimetral edge (6) which surrounds the base (2), a removable portion (21) extending as a prolongation of the perimetral edge (6) away from the base (2). The package further comprises: a closing film (10) engaged with a portion of the perimetral edge (6) and with the removable portion (21) for defining a housing compartment (22) for the product, a gripping portion (22) emerging from the perimetral edge (6); the removable portion (21) and at least a part of the closing film (10) are configured for being separated from the support (1) during an opening step of the package. The package is configured for defining a closing condition in which: the closing film in cooperation with the support (1) prevents access to the housing compartment (5), and the removable portion (21) is aligned with at least a portion (6a) of the perimetral edge (6) from which it extends as a prolongation. The removable portion (21) has a cavity (21a) the concavity whereof, at least in the closed condition of the package, faces the perimetral edge (6); the gripping portion (22) is disposed, at least in the closed condition of the package, within said cavity (21a). The present invention also relates to a process and an apparatus for making said package.
