Abstract: A system and a method for closing, in an automated way, at least one package having a reversibly closeable interlocking element comprising a first complementary element and a second complementary element extending between two extremities. The system includes a pressing element, configured to press the first complementary element against the second complementary element by sliding between the two extremities, and a counteracting element, configured to stop the second complementary element when the pressing element presses the first complementary element against the second complementary element, in such a way that the first complementary element and the second complementary element interlock with each other along their entire length.

Abstract: The present invention relates to a method for making airtight packages (100) made of flexible material that are configured to seal an environment inside the package with respect to an external environment, said packages (100) comprising a front panel (1), a back panel (2) and two side gussets (3, 4) provided at opposite ends of the front panel (1) and of the back panel (2) so as to connect the front panel (1) to the back panel (2). The method comprises a first step of folding a sheet (60) made of flexible material along two first fold lines (L1) which are mutually parallel so as to form a tubular element (61).

Abstract: A flexible material package (100, 200) is presented comprising a reinforcing element (3) and a first sealed area (103) positioned close to the upper end of the package (100, 200) and preferably configured so as to close the package (100, 200), wherein the reinforcing element (3) is at least partially positioned within the first sealed area (103), the package (100, 200) further comprising gripping means positioned vertically below the reinforcing element (3) and configured so as to be used to support the package (100, 200). A closing method, a filling method and a formation method of the package (100, 200) are also presented.

Abstract: The present invention relates to a method for making packages (100) made of flexible material. The method comprises a first step which consists in providing a first strip (19) and a second strip (20) made of flexible material, positioned on top of each other along a conveying direction and preferably having the same width. Moreover, the method comprises a second step of securing the first strip (19) to the second strip (20) by means of a welding surface (24) which extends in a direction perpendicular to the conveying direction of the first and the second strip (19, 20) for a first length (h4) which is less than the width (h3) of each of the first and the second strip (19, 20); wherein the welding surface (24) is positioned at a first side edge (39) of the first and the second strip (19, 20). In addition, the present invention also comprises a machine (200) which allows using such method.
