Abstract: A method and apparatus for sealing a bag made of a polymeric material by applying heat activated layers on different portions of the bag, wherein the first adhesive layer and the second adhesive layer have respective heat activation temperatures below the softening point temperature of the polymeric material; after creasing the bag along a fold line, applying heat at a temperature below the softening point temperature of the polymeric material to activate the first adhesive layer and the second adhesive layer to adhesive states after the bag has been filled with contents; and folding the bag to form an adhesive-to adhesive seal by contact between the heat activated first adhesive layer and the heat activated second adhesive layer.

Abstract: A polymeric woven bag has a first panel and a second panel and an open end of the bag to be pinched closed. A first layer of heat activated adhesive material is on a portion of the bag to form an adhesive-to-adhesive seal by contact with a second layer of heat activated adhesive material on a portion of the bag. second panel, wherein a chemical family of the adhesive layers comprises, distillates, petroleum and ethanamine or naphthene components, and wherein the first adhesive layer and the second adhesive layer have respective heat activation temperatures below the softening point temperature of the polymeric bag material.

Abstract: A method and apparatus for making a stepped end on a tube of flexible material includes a tube slitting station having a slitting tool with double edge slitting to provide respective slits beside a first panel and beside a second panel, respectively; a first trimming station trimming a first panel of the tube to a first shortened length, a second trimming station trimming the side gussets to a second length, wherein the second length is longer than the first shortened length; and an adhesive applying station applying adhesive on the tube above and below a fold line across the tube, wherein the tube is adapted to be folded along the fold line, and the adhesive material is adapted to form an adhesive to adhesive seal above and below the fold line.

Abstract: A package is fabricated with a first polymer film having reverse printed matter thereon, a second polymer film laminated to the first polymer film to provide a composite, wherein the printed matter is between the first and second polymer films, and a woven bag enclosed by the composite, wherein the second polymer film of the composite isolates the printed matter from cross contamination with contents intended for the woven bag.

Abstract: A packaging for reams of cut paper involving tear tapes made of plastic or paper maternal inserted into the ream wrap. The tear tapes may be pulled to tear off and open one end of the wrapped ream, leaving the remaining packaging intact to serve as a storage and dispenser for partial reams of paper.

Abstract: A method of making a bag by engaging an inverted zipper assembly with a first panel of a polymeric tube, bonding the first panel and the zipper assembly to form a seal therebetween, folding over a stepped end of the tube onto the zipper assembly; and bonding the stepped end and the zipper assembly to form a seal therebetween.

Abstract: A bag and zipper assembly includes, side gussets of the bag are at inwardly folded positions between first and second panels. Each side gusset of the bag has a set of one or more gusset openings adjacent an open end of the bag. The first panel has a corresponding set of one or more panel openings, and adhesive extends in each of the openings for the adhesive to adhere the side gussets to the first panel and restrain each side gusset from movement outwardly from between the first and second panels.

Abstract: The present invention relates to a method for applying tear tape to a wrapper by advancing a web by continuous movement in a machine direction. The tear tape is advanced in a cross direction, and cut in order to provide a cut portion of the tear tape. The cut portion of the tear tape is then advanced in the cross direction and into alignment with a width of the web and applied to the web without stopping the web from its continuous movement in the machine direction.

Abstract: A laminated medical examination paper for use in a doctor's office or other medical or health care delivery setting.

Abstract: The present invention relates to a system and method for applying tear tape to a packaging substrate. Features of the system include a tear tape applicator unit comprising a laser/tear tape unwind assembly and a tear tape applicator assembly and a winder comprising an unwind roll and a rewind roll. A packaging substrate is advanced from the unwind roll to the rewind roll. The tear tape applicator unit interfaces the winder such that at least one portion of a tear tape is cut by the laser/tear tape unwind assembly and applied to the web of packaging substrate by the tear tape applicator assembly. Features of the method include advancing a web of a packaging substrate along a rewinding line from an unwind end to a rewind end, cutting at least one portion of a tear tape, advancing said at least one portion of said tear tape toward said rewinding line, and applying said at least one portion of said tear tape to said web.

Abstract: A new high strength poly one-side ream wrapper made by utilizing copolymer and/or terpolymer resins.
