The machine and the method disclosed use a panel plastic film that is longitudinally folded into top and bottom halves before slitting along the fold. The halves are simultaneously transported ensuring print registration and requiring a single accumulator in the longitudinal direction. Side gusset pieces are inserted between the top and bottom halves through an initial gap enlarged by a pair of timing belts. The top and bottom halves partly sealed with the side gusset pieces are pulled away from each other and a means gives the ends of the side gusset pieces the shape of a rhomboid. Bottom gusset film is vertically sealed along the vertical axis of the rhomboid shaped ends of the side gusset pieces with the seal extending to the folded portions of the top and bottom halves. Longitudinal sealing and transverse sealing before cutting ensure sealing of the bottom gusset and side gussets.

The invention relates to a resealable package (1, 1, 1), comprising a package body (2) having a first side wall (4), a second side wall (6) opposite the first side wall (4), an openable top end (8) and a closed bottom end (10), wherein a portion (12) of the first side wall (4) protrudes beyond the second side wall (6) at the top end (8) in a direction from the bottom end (10) to the top end (8), and a closure element (18) which is releasably adhered to an inner surface (14) of the portion (12) of the first side wall (4) which protrudes beyond the second side wall (6) and the second side wall (6) so as to close the top end (8). Upon removal of the closure element (18) from the package body (2), a resealable adhesive arrangement (20, 22; 23; 25) is exposed so as to allow the inner surface (14) of the portion (12) of the first side wall (4) which protrudes beyond the second side wall (6) and an outer surface (16) of the second side wall (6) to be resealably adhered to one another in a position to close the top end (8). Further, the invention relates to a method and an apparatus (100) for producing the resealable package (1, 1, 1).

A breathable bag (1) especially suitable for packaging horticultural products (2) comprising a mesh casing (3), which is capable of housing the products to be packaged and at least one first band (5) of flexible material applied on the outside of and joined to the casing by affixed areas (6, 7) affixed to said casing, the first band covering a region (8) of the casing that has a hole (9), the practical access to the hole (9) being prevented by the affixed joining areas (6, 7) between the first band (5) and the casing (3), and the first band (5) being equipped with at least one tear line (10) that determines in the first band (5) a removable portion (5c) from the casing (3) that is sufficient to leave uncovered or to open a practical access to said opening (9).

In order to successively make plastic bags each of which includes panel portions, side gusset portions and a zipper portion, a web of panel material 9 is folded and folded back along longitudinal folded lines 14, 15 and 16 and longitudinal folded back lines 17 and 18 into superposed two layers having opposite side edges at each of which a folded portion is formed. The web of panel material 9 is slit along the longitudinal folded line 16 into two divided parts after being folded and folded back. The divided parts are separated and spaced from each other. In addition, the folded portions are split at positions into sprit portions and removed at the positions partially, a body of zipper material being disposed between the sprit portions.

The product efficiency of bags each with an end face part is increased. A panel webs is guided to be divided along a line of weakness of the panel web and to be folded along division edges of the panel web. This guiding of the first panel and temporary sealed sections cause a side gusset to be cut open along a line of weakness of the side gusset such that open surfaces are formed. After the forming of the open surfaces, an end face web is supplied to be superposed on folded parts of the panel web and the open surfaces of the side gusset.

A controller for a pouch-making machine for manufacturing a pouch while feeding a pair of film materials each provided with a reference mark that indicates a reference position for layering the film materials together, includes a driven roller shift unit for independently shifting each shaft of a pair of driven rollers that rotate being driven by the pair of film materials being fed and a control unit for controlling the driven roller shift unit based on a result of an image-shooting unit shooting images of the reference marks, so that positions of the reference marks provided on the pair of film materials coincide.
