Abstract
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.
