摘要： Plastic bags, rolls of plastic bags, and tubular blown film processes for making rolls of plastic bags. The rolls of plastic bags include a tubular blown film with a plurality of perforation lines along which plastic bags are separated from the roll. The perforation lines are formed so that portions of the lips of the plastic bags are offset from each other. The offset portions of the lips facilitate opening of the bags.

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： An improved method and mechanism for forming a chain of laterally interconnected plastic bags which have confronting releasably interlocking rib and groove profile elements on the inner confronting wall surfaces or at the edge of said surface including advancing a tube or a folded film of plastic bag material having interlocked rib and groove profile elements, forming spaced spot seals at the profile element and alternately at another location to permanently join the layers of material and permanently join the rib and groove elements over the area of the spot, forming lateral seals extending the width of the material at the location of the spot seals to provide side seams for the adjacent bags, and cutting through the material along the center of the seam to partially separate the bags with the cuts extending a predetermined distance partially into the spot seals to control their remaining strength and control the separation force needed to separate adjacent bags.

摘要： A plurality of expandable bags are serially connected lengthwise in roll form. Each bag is of substantially long length and has an expandable gusset near one end thereof and traversely of the length. The gusset end of each bag is respectively connected to the filling or open end of the next bag by perforated or weakened structure. Various modifications of the position of the opening are incorporated. Also, the bags are rolled into serial form in a compact package for distribution and use with the gusset and opening portions of each bag being rolled inwardly to the inside of the roll, or outwardly to the outside of the roll. The method of making these serially connected bags in roll form is also included.

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.
