Methods of making slide-zippered reclosable packages are provided. In one embodiment, a pair of opposing film extensions are provided on each package between which a zipper and slider are attached. In another embodiment, sliders are inserted on to zippered packages output from a form-fill-seal machine or the like. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and then a slider is inserted on to the zipper. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and a slider is inserted on to each zipper, either before or after zipper sealing.

A vented pouch arrangement is described which comprises: first and second opposed panel sections; a base gusset member; and, a gas filter arrangement oriented in one of the panel sections. The gusset member is preferably oriented between the panel sections; along ends thereof, to form a base by which the arrangement can be stood up during use. Preferably, the arrangement is provided with a rib and trough closure arrangement extending thereacross. In this manner, opening and reclosing the bag construction, for access to material therein, is facilitated. A method for formation of such a pouch arrangement, and methods of use, are also described.

A mechanism and method of attaching to a laminated plastic sheet a fastener profile wherein the preformed sheet is removed from a roll and passed through a heating chamber having controlled humidity and thereafter passing said sheet over a roll which forms a joining zone with an extruded plastic profile strip fed onto the sheet with a jet of air directed thereagainst, and the joined sheet and strip thereafter passing through a chamber where the strip is cooled and the heat in the sheet is maintained.

A bag making apparatus includes a welding device for welding a sheet panel and a strip member in a zone where the sheet panel is intermittently fed by a feed device and a cut device disposed downstream of the welding device to cross-cut the sheet panel and the strip member every intermitted feed cycle. The welding device include a pressure unit for pressurizing the sheet panel and the strip member superposed on each other and a laser unit for irradiating the sheet panel or the strip member with a laser beam at an irradiation position upstream of a pressure position of the pressure unit to melt the sheet panel or the strip member. The pressure unit and the laser unit are configured to be movable together upstream and downstream relative to the sheet panel while maintaining a relative positional relationship between the pressure position and the irradiation position.

The present invention provides a method of making re-closable package (10) and a product made therefrom. The said method comprises providing a first web (46) and a second web (50), folding a predetermined portion (P) of the first web (46) into a V-shape (58) thereby forming an extended portion and cutting the V-shape (58) of the first web (46) to form a pair of extended panels (62). A re-closable zipper (42) sealed with the extended panels (62). The first web (46) sealed with the second web (50) at a first sealing zone (SZ1) and second sealing zone (SZ2). Subsequently, cut the first web (46) and the second web (50) at the first sealing zone (SZ1) thereby obtaining a re-closable package (10). The said re-closable package (10) comprising a first panel (14), a second panel (18) and optionally side gussets (22, 26) and a bottom gusset (30).
