a woven bag material layer;
another laminating polymer or adhesive laminating the second oriented polymer film to the woven bag material layer;
the printed matter being between the first and second oriented polymer films while the oriented second polymer film isolates the printed matter from cross contamination with contents intended for the flexible woven bag;
the woven bag material layer being the final structure inside the bag; and
the first oriented polymer film, the laminating polymer or adhesive, the second oriented polymer film and said another laminating polymer or adhesive providing a flexible composite, and the flexible composite enclosing the woven bag material layer and protecting the woven bag material layer.
2. The flexible woven bag of claim 1 wherein the printed matter comprises water based ink.
3. The flexible woven bag of claim 1 wherein the second oriented polymer film and the first oriented polymer film are laminated together and are joined at a seam and are laminated to the woven bag material layer, providing a tubular structure.
4. The flexible woven bag of claim 1 wherein the second oriented polymer film and the first oriented polymer film are laminated together and are joined together at side margins and are laminated to the woven bag material layer, providing a tubular structure.
5. The flexible woven bag of claim 1 wherein the woven bag material layer is seamless or has a seam, and the woven bag material layer, the second oriented polymer film and the first oriented polymer film are laminated together providing a tubular structure.
6. The flexible woven bag of claim 1 wherein the woven bag material layer comprises two pieces joined together at side margins, and the woven bag material layer, the second oriented polymer film and the first oriented polymer film are laminated together providing a tubular structure.
