A reclosable bag includes: first and second plies extending from a first side to a second side and from atop bottom to a top; a seal joining the first and second plies arranged near the bottom of the bag; a reclosing material disposed on an interior surface of one of the first and second plies; a release material disposed between the reclosing material and the other of the first and second plies; and a bag opening zone extending between the top and the bottom.
First claim
Opening claim text (preview).
What is claimed is: 1. A web of interconnected reclosable bags, wherein each of the reclosable bags in the web comprises: first and second plies extending from a first side to a second side and from a bottom to a top; a seal joining the first and second plies arranged near the bottom of the bag; a reclosing material disposed on an interior surface of one of the first and second plies; a release material disposed between the reclosing material and the other of the first and second plies; and a bag opening zone extending between the top and the bottom; wherein the reclosable bags in the web are separated by lines of weakness; wherein, in each of the reclosable bags, the bag opening zone comprises a first and second opening lines of weakness in the first ply and a third opening line of weakness in the second ply; wherein each of the reclosable bags further comprises a fourth opening line of weakness in the first ply and arranged between the first and second lines of weakness; and wherein each of the reclosable bags further comprises a separating seal extending from the top to the bottom to form a reclosing flap between the separating seal and the first side. 2. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the reclosing and release materials are arranged between the bag opening zone and the first side. 3. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the bag opening zone comprises a first and second opening lines of weakness in the first ply. 4. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the third opening line of weakness is aligned with the second opening line of weakness. 5. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the separating seal is arranged between the first opening line of weakness and the first side. 6. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the separating seal is arranged between the first and the fourth opening lines of weakness. 7. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the reclosing and release materials are arranged between the first and second opening lines of weakness. 8. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the reclosing and release materials are arranged between the fourth and second opening lines of weakness. 9. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the reclosing material is formed in a strip extending from the top to the bottom of the bag proximate the first side. 10. The web of interconnected reclosable bags of claim 1 , wherein, in each of the reclosable bags, the bag opening zone extends entirely from the top to the bottom of the bag.
