Claims
- 1. A bag comprised of at least two superimposed sheets of film material having at least a portion of their superimposed edges being permanently sealed, wherein at least one of the sheets is a composite film material provided with a pressure sensitive adhesive protected from inadvertent adherence, the adhesive-bearing film sheet being releasably sealable to the other film sheet when pressed thereagainst to create a seal perimeter, wherein an interior of the bag is comprised within the seal perimeter.
- 2. The bag according to claim 1 wherein the interior is further comprised within the permanently sealed portion of the superimposed edges.
- 3. The bag according to claim 1 wherein the bag has four pairs of superimposed edges, and at least one pair of the superimposed edges is permanently sealed.
- 4. A bag comprised of a first sheet of film material and a second sheet of film material wherein at least one of the sheets is a composite film material provided with a pressure sensitive adhesive protected from inadvertent adherence, the adhesive-bearing film sheet being releasably sealable to the other film sheet when pressed thereagainst to create a seal perimeter, wherein an interior of the bag is comprised within the seal perimeter.
- 5. A bag comprised of a sheet having a first portion with at least one first portion free edge, a second portion with at least one second portion free edge, and a juncture area between the first portion and the second portion, wherein at least one of the first portion or the second portion is comprised of a composite film material provided with a pressure sensitive adhesive protected from inadvertent adherence, and wherein the first portion is overlaid onto the second portion by folding about the juncture area, the first and second portions being releasably sealable to each other along a seal perimeter created by pressing one of the portions against the other of the portions, wherein an interior of the bag is comprised within the seal perimeter.
- 6. The bag according to claim 5 wherein both of the first portion and the second portion are comprised of a composite film material provided with a pressure sensitive adhesive protected from inadvertent adherence.
- 7. The bag according to claim 6 wherein the juncture area is comprised of a composite film material provided with a pressure sensitive adhesive protected from inadvertent adherence.
- 8. The bag according to claim 7 wherein the sheet is a unitary sheet of composite film material provided with a pressure sensitive adhesive protected from inadvertent adherence.
- 9. The bag according to claim 5 wherein the interior is further comprised within the juncture area.
- 10. The bag according to claim 5 wherein at least a portion of the first portion free edge is permanently sealed to at least a portion of the second portion free edge.
- 11. A bag comprised of a sheet having a first portion with at least one first portion free edge, a second portion with at least one second portion free edge, and a juncture area between the first portion and the second portion, wherein at least one of the first portion or the second portion is comprised of a composite film material provided with a pressure sensitive adhesive protected from inadvertent adherence, at least one of the first or second portion free edges is provided with an opening indication means that visually contrasts with the other first or second portion free edges, and wherein the first portion is overlaid onto the second portion by folding about the juncture area, the first and second portions being releasably sealable to each other along a seal perimeter created by pressing one of the portions against the other of the portions, and the seal perimeter further comprising the juncture area.
- 12. The bag of any of claims 1, 4, 5, or 11 wherein the composite film material is a three-dimensional composite sheet material having a first side and a second side, wherein the first side comprises at least one region having a plurality of spaced three-dimensional protrusions extending outwardly from the first side, the protrusions being separated by an interconnected network of three-dimensional spaces between adjacent protrusions, and the spaces being partially filled with an adhesive.
- 13. The bag according to claim 12 wherein the plurality of protrusions form an amorphous pattern of interlocking convex polygons each having a finite number of substantially linear sides with facing sides of adjacent polygons being substantially parallel.
- 14. The bag according to any of claims 1, 4, 5, or 11 wherein the interior is divided into a plurality of interiors by releasably sealing the adhesive-bearing film sheet to create a plurality of seal perimeters.
- 15. The bag according to any of claims 1, 4, 5, or 11 further comprising an opening indication means.
- 16. The bag according to claim 15 wherein the opening indication means is comprised of a color indication means.
- 17. The bag according to claim 15 wherein the opening indication means is comprised of a printing indication means.
- 18. The bag according to any of claims 1, 4, 5, or 11 wherein the sheet is provided with decorative printing.
- 19. A method of storing an item comprising placing the item in the bag according to any of claims 1, 4, 5, or 11, releasably sealing the bag by creating a seal perimeter, and placing the sealed bag in a storage location.
- 20. The method according to claim 19, wherein the item is a vegetable and the storage location is a refrigerator.
