Definitions

  • the invention relates to pouches formed of flexible materials. More specifically, the present invention relates to a gusseted pouch adapted to resist cracking due to flexing.
  • Laminates used for flexible packaging applications such as gusseted pouches, often contain a barrier layer designed to prevent or control the flow of oxygen and moisture therethrough.
  • barrier materials are used for this purpose.
  • the barrier material may be compromised cracks or pinholes due to flexing or bending of the laminate.
  • a common area for the compromise is the gusset. It would be beneficial to provide a pouch, constructed of a laminate having a barrier material therein, that has a gusseted insert adapted to resist flex-cracking or pinholes.
  • a pouch is defined by a first and second panel of a flexible laminate.
  • the panels each have an outside face, an inside face and a barrier layer disposed between the outside and inside faces.
  • the edge portions of the inside faces of the two panels are bonded to one another to form the pouch reservoir.

It is preferable that the sealing layer 22 of the first panel 20 be sealable to the sealing layer 32 of the second panel 30 in forming the pouch 10.
  • a second layer 104 is preferably a webbing material, such as nylon, polyester or polypropylene. The second layer 104 preferably provides strength to the panels 20, 30. The second layer 104 is preferably coated with a barrier material 106 that provides resistance against oxygen permeability.
  • the barrier layer is typically a metal foil and may be made from aluminum oxide, silicone oxide or other similar material.
  • Exemplary second layer and barrier combinations may be aluminum oxide coated polyester, silicone oxide coated polyester, metallized polyester, metallized oriented polypropylene or polyvinyl-dichloride coated polyester or some other suitable combination.
  • a third layer 108 defines the outer face 24, 34 of the respective first and second panels 20, 30. The third layer may be printable as desired.
  • the first and second gusset panels 40, 50 preferably have an identical three layer construction.
  • a first gusset layer 202 is a sealing layer and may be constructed of polyethylene, polypropylene or some other desirable material.
  • the first gusset layer 202 makes up an outer face 42, 52 of the first and second gusset panels 40, 50. Regardless of the material used for construction, it is preferable that the material first gusset layer 202 be sealable to other surfaces made of the same material.
  • a second gusset layer 204 is preferably a strength layer and may be made of nylon or a polyester webbing material.
  • the second gusset layer 204 is preferably coated with a barrier material 206, which may be aluminum oxide, silicone oxide or similar material.
  • the barrier material 206 preferably resists the permeation of oxygen through the gusset panels 40, 50.
  • a third gusset layer 208 is a sealing layer, similar to the first gusset layer 202.
  • the third gusset layer 208 may be made from polypropylene, polyethylene or other sealing material.
  • the third gusset layer 208 makes up an inner face 44, 54 of the first and second gusset panels. It is preferable that the third gusset layer 208 be sealable to the first layer 102 of the first and second panels 20, 30. [0017] Illustrated in Fig.
  • a fourth layer 310 is disposed between second layer 204 and third gusset layers 208.
  • the fourth layer 310 is preferably a strength layer, and is generally the same material, nylon or a polyester webbing, used for the third layer 208.
  • the fourth layer 310 may also be coated with a barrier material 312 in a fashion similar to the coating 206 of the second layer 204.
  • the fourth layer 310 is intended to increase the strength and permeability resistance of the gusset panels 40, 50.
  • a first layer 202 is preferably of the same construction as the first layer 202 of the gusset panel of Fig. 4.
  • the panels 20, 30, 40 and 50 are preferably heat sealed together, although other forms of attachment may be utilized.
  • a top edge portion 42a of the outer face 42 of the first gusset panel 40 is sealed to a top edge portion 52a of the outer face 52 of the second gusset panel 50.
  • a gusset seal 14 is formed between the gusset panels 40, 50.
