Bandolier format packaging
A product and method for producing a string of individual sealed, filled packages separated by perforations. A string of separate packages optionally may be enclosed in a cardboard or other container designed to sit in a pantry or other location for dispensing of individual units. Perforations in the packaging film between separate packages provide a tear point to aid in separating one package from the next. There are several advantages to this format including easy placement of the string of packages into a carton for shipping or dispensing, and the ability to hang a string of packages in locations without the need to attach the packages to a backing strip. The perforations between packages facilitate the packaging and transportation of the entire string or bandolier, and facilitate the removal and use of a separate package.
1. A method for forming, packaging, and dispensing a string of sealed food product packages using a vertical form, fill and seal machine, said method comprising the steps of:
(a) guiding a packaging material into a position such that said packaging material is wrapped around a delivery tube of said form, fill and seal machine, wherein said packaging material comprises oriented graphics which appear sideways as the packaging material is fed through a vertical form, fill and seal machine;
(b) sealing adjacent portions of said packaging material to form a tube of packaging material;
(c) for each of said packages:
(1) forming a first transverse seal across said tube of packaging material;
(2) delivering a product into said tube of packaging material above said first transverse seal; and,
(3) forming a second transverse seal across said tube of packaging material using a heat-sealing jaw assembly to create a sealed package filled with said product;
(d) creating a transverse line of perforations along said second transverse seal using a knife positioned within said heat-sealing jaw assembly; and,
(e) placing said string of sealed food product packages in a package dispenser having a closeable opening via said closeable opening, such that said dispenser holds two or more sealed food packages;
(f) dispensing a loose end of said string of sealed food product packages from a dispensing opening, wherein said oriented graphics are properly viewable when said transverse seals are vertically oriented.
2. The method of claim 1 wherein each of said packages is a flexible multi-pack package comprising:
a first bag having a first transverse seal, and a second transverse seal, wherein the first transverse seal and the second transverse seal are on opposite sides of the first bag; and,
a second bag having a third transverse seal, wherein said second bag shares the second transverse seal with the first bag and is flexibly attached to said first bag by the second transverse seal, and further wherein the second transverse seal and the third transverse seal are on opposite sides of the second bag; wherein the first, second and third transverse seals are parallel to each other.
3. The method of claim 1 wherein said packaging material is a packaging film comprising at least one layer selected from the group consisting of polypropylene, polyester, polyethylene, paper, polyolefin extrusions, and adhesive laminates, or any combinations thereof.
