A food storage bag may include a flexible substrate defining first and second opposing sidewalls, a closed bottom and an open top, and first and second wires extending along the first and second sidewalls of the flexible substrate. The first and second wires may each have a shape defining a series of peaks and troughs such that the opposing peaks and troughs may be twisted together to close the flexible substrate at different lengths along the first and second sidewalls.

A reclosable flexible package for storing a food product and a method of manufacture thereof are provided. The package includes a flexible film side wall, a closed first end, a closed second end portion that can be separated from the side wall to provide an access opening, and a collar. The collar can be formed in the side wall or attached to the side wall. The collar is more rigid than adjacent portions of the side wall and is rotatable about the longitudinal axis of the package to twist portions of the side wall and block access to the opening after removal of the second end portion.
