Definitions

  • FIG 6 is a perspective view of a bag having a non-reusable closure partially installed therein.
  • FIGS 7a-c are perspective views of the non-reusable closure of one embodiment of the present invention illustrating the targeted openable region.
  • membrane 28 can also comprise instructional indicia 42 on user-facing surface 30 of membrane 28.
  • instructional indicia 42 can comprise printing including words, pictures, symbols, illustrations, and the like, to indicate to the user where and how to open the non-reusable closure 26.
  • Bags containing at least about 15 pounds of a particulate, flowable composition can be difficult to pick up and carry because of the weight of material contained therein, especially when the materials used for construction of the bag are slippery or difficult to grip. Thus, bags containing such materials should ideally not be slippery or difficult to grip.
  • the material of the inner surface of the laminate can have a relatively low melting point such that it melts to enable heat sealing, whereas the outer surface can have a higher melting point such that it does not melt during heat sealing.
  • an outer layer can be Nylon 6,6, and an inner layer can be a co-extruded blend of linear low density polyethylene, medium density polyethylene, and linear low density polyethylene.
  • densities of polyethylene, "low”, “medium”, “high”, “ultra low/very low” have meanings as used and understood in the art for such materials.
  • Air pressure equalization described the escape of and entrance of air into and out bag 10. It can be important to allow air to escape from bag 10 during shipping and handling of the bags. When bags are stacked on pallets for shipping, the weight of the bags on top of each other can cause the bags to burst if there is no way for air to escape from the bags. However, once air is squeezed out of the bags, the bags can have an unappealing, 'vacuum packed', lumpy appearance. Thus, it can be desirable to allow air back into the bags once the bags are unloaded for display and sale.
  • a seal bar having one or more gaps thereon wherein the gapped part of the seal bar would not touch the material being sealed, thus leaving an unsealed portion or "gap.”
  • a “skip gap seal” can be formed on the seal formed at the bottom of the bag, at the seal formed when attaching a first portion of the membrane to the front surface of the bag, or when attaching the second portion of the membrane to the rear surface of the bag.
  • a “skip gap seal” can be formed, for example in the final seal sealing the bag closed once it has been filled. Each gap can be of from about 70 ⁇ to about 10mm in length. If no non-reusable closure is used, gap(s) can be formed in any of the seals used to form the bag, as required for appropriate desired air equalization.
  • the gap(s) can be straight sided and can have a cylindrical or tubular shape or can be shaped and/or curved and of a length that would still allow air to pass there through, but which would provide a barrier to infestation (i.e. provide a longer, more complicated path for potentially infesting organisms). Any shaped gap can be incorporated or formed into the seal bar of the heat sealing apparatus, as would be understood by those skilled in the art.
  • Embodiments of the present invention also can include methods of enhancing palatability of an oxidizable particulate, flowable composition after storage comprising the steps of:
  • a bag of one embodiment of the present invention can be constructed as follows.
  • a plastic laminate film comprising a 19 micron thick layer of Nylon 6,6 bonded by adhesive lamination to a 155 micron thick co-extruded layer of metallocene linear low density polyethylene, medium density polyethylene, and metallocene linear low density polyethylene, (available for example from Exopack, Spartanburg, SC, USA), is used for forming the bag.
  • metallocene linear low density polyethylene e.g., polyethylene
  • medium density polyethylene e-extruded low density polyethylene
  • metallocene linear low density polyethylene available for example from Exopack, Spartanburg, SC, USA
  • a non-reusable closure membrane formed from a blend of low density polyethylene and ultra low density polyethylene is attached, by co-extrusion therewith, to a track of a slider and track zipper, for example a Slide-Rite ® zipper from Pactive Corp., Lake Forest, II, USA.
  • a track of a slider track zipper device is formed high density polyethylene.
  • the track and the membrane are co-extruded.
  • the membrane has a width w of about 3 inches as measured from inner edge to inner edge of the track.
  • the membrane has a targeted opening region of 1.5 inches in length, disposed along the length of the membrane, and formed form a plurality of perforations.
