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.

摘要： A multi-ply plastic bag from a continuous strip of bags on a roll is supplied to a user with the top of the bag partially opened. A tear line between the bottom of a leading bag and a top of a subsequent bag separates the individual bags. A broad slit centrally located in the tear line passes through all but one ply of the strip of bags. The bag dispenser has an upwardly projecting tongue which engages the slit in the tear line when a user draws a bag from the dispenser. The tongue impedes the subsequent bag from moving forward. The adjacent bags separate along the tear line. The ply which does not have a slit rides over the tongue and pulls apart the plies at the opening of the subsequent bag before the leading bag completely separates from the subsequent bag.

摘要： A coil of an interconnected chain of open bags is provided in which the coil has a center opening having a diameter at least as great as the transverse dimension of the bags. A dispenser is provided on which a coil of bags is mounted. An end of the chain is pulled from the center opening and fed around a tapered mandrel and thence over a feed control mandrel oriented in angular relationship with the tapered mandrel. The web is then fed to a bagging machine for dispensing, loading and closing of the bags. The table on which the coil is mounted is rotatable so that the orientation of a span of bags running from the coil to the tapered mandrel remains substantially constant as the web is fed.

摘要： A method and apparatus for producing continuous bags, each bag having an opening on one side from a length of continuous tubing is disclosed. The bags are produced along a direction of production and each bag produced has a sealed end and line of perforation opposite to the sealed end. Each bag is positioned with its sealed end immediately adjacent to the line of perforation of an adjacent bag. The bags are produced by advancing a length of continuous tubing along the direction of production and sealing the tubing at a first location by a sealing means to form a sealed end of a first bag and substantially simultaneously perforating the tubing at a second location immediately adjacent to the sealed end of the first bag by a perforating means to form a line of perforation of a second bag. The second bag is immediately adjacent to the first bag. One layer of the tubing is then severed at the line of perforation without substantially severing the other layer by moving the upper layer relative to the other layer in a direction opposite to the direction of production. Lastly, the method comprises the step of advancing the tubing along the direction of production to form the plurality of continuous bags.

摘要： The present invention is a method of continuously making thermoplastic film bags having one-side-free for separation from an opposite side. The method includes providing a continuous tube of thermoplastic film for formation of the bag, such tube having a continuous surface which forms opposing sides of the bags. The tube is directed to a bag forming means which continuously flattens the tube into at least the opposing sides of the bag. The tube must intermittently be partially severed on one of the opposing sides at intervals corresponding to single bag lengths, such severance being made at a location for providing detachable separation of the one wall from the opposing wall. Next a sealed seam is formed across the tube at intervals which provide bottoms to each of the bags, and the bags are then collected in a stack where they are substantially aligned followed by fusing the stack of substantially aligned bags adjacent the severance in the one side for separating the bags from stack one side at a time.

摘要： The apparatus for manufacturing bags in plastic material comprises a welding assembly having a pair of fixed jaws and a jaw which is movable therebetween for clamping respective alternately advancing tubular bands made of plastic material. A cutting element, carried by a flexible belt rotatable on the movable jaw, is adapted to cut the bands upon clamping the movable jaw on the fixed jaws. An assembly for extracting and accumulating the bags is provided with a plurality of needles at each fixed jaw and actuated with reciprocating motion in the direction of sliding of the movable jaw so as to penetrate a bag clamped between the jaws. The apparatus also comprises a fork for placing the bag adjacent to the previously produced bags supported on the needles, and a slider for unloading a pack of manufactured bags.

摘要： A collapsible bag and method of making it from blanks of a flexible material which are cut from an elongate web substantially without wasting any material between adjacent blanks. Each blank has a circumferentially continuous central portion and four substantially identical isosceles triangular portions at each end of the blank. Adjacent sides of adjacent triangular portions are connected together to provide, when the bag is expanded or filled, generally square ends which are interconnected by generally rectangular side walls. An access opening is provided in an end of the bag by terminating the connections of its triangular portions short of their apexes. Preferably, a spout is received in the access opening and connected to the triangular portions.
