摘要： To make blocks of bags having blocked stubs, which are joined by perforation lines substantially only to the lower opening-defining edge of each block, which lower edge is separated by a substantially continuous slit from the upper opening-defining edge, a tubular web of synthetic thermoplastic material is formed in partial regions with perforation lines extending through both plies. Only the upper ply is cut to form separating slits extending substantially throughout the width of that upper ply. The bags are then separated from the tubular web by hot-wire welding and are stacked. To make blocks of bags in which each bag is joined only at its rear wall to the stub, which serves to stack and retain the bag, transverse perforation lines consisting of holes or slits are formed in the upper ply at the opening-defining edges of the bags to be formed, and both plies are subsequently formed with transverse perforation slits, which are so offset that over the width of the initially formed perforation holes the upper ply is entirely separated from the stub and the lower ply is joined to the stub by lands adjacent to the initially formed overlying perforation line.

摘要： In an apparatus for making plastics carrier bags from a web of tubular film of thermoplastic material, a feeding mechanism intermittently conveys the webs by one bag width and a severing mechanism cuts the web into half tubes along an undulating curve. A carriage displaceable in the machine frame transversely to the feeding direction of the web is reciprocated by a drive derived from a first rotating control cam through gearing. A cutting knife pivotable in the carriage about its longitudinal axis passes through the plane of the tube about an axis perpendicular thereto and is so controlled by an oscillating drive derived from a second rotating control cam that its edge is substantially tangential to the undulating curve at the cutting point. A detour assembly retards one of the half tubes to bring the bag side edge zones into phase and each half tube is formed into bags by a transverse sever-sealing device.

摘要： A continuous film sheet having a width in a horizontal direction is unwound from a film roll with its axis being substantially horizontally kept. The direction of extension of the film sheet is changed so as to have its width in a vertical direction before the film sheet is slit along its center line into two continuous strips. The two continuous strips are superposed on each other and heat-sealed in lengthwise and transverse directions to form a plurality of rectangular sections defined by heat-sealed sides. The heat-sealed sheet is then slit and cut into separated envelopes having their respective three heat-sealed edges.

摘要： A trifold side seamed plastic produce bag includes a front wall and a taller back wall, first and second side edges sealed together and a seamless bag bottom. The taller back wall provides means for finding the bag opening. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method and apparatus for producing the bags includes a slitter that removes a strip of plastic from only the top layer of the bag stream to form an extended flap on each bag. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls.

摘要： A thermoplastic bag structure and method for making and packaging thermoplastic bags such that their tops are easily identified and the bags are easily opened. The method for producing these bags begins with cutting a flattened thermoplastic tube into two portions. At least one of the two portions is then collapsed to form a sheet of material having a pair of thermoplastic layers, a straight folded bottom edge and a pair of top edges, at least one of which has a skewed-cut. Bag side structures are formed in the sheet of material at about bag-width distances apart. The bags are then folded a predetermined number of times, in a direction transverse to the bag side structures, so that the skewed-cut top edge(s) of each of the bags remains exposed.
