Abstract: A flexible package that can include first and second sidewalls. The first and second sidewalls being joined by a bottom portion and seams that define first and second sides. The package can have an opening opposite the bottom portion, a first plurality of magnetic regions, and a second plurality of magnetic regions. The first plurality of magnetic regions can be disposed on the first sidewall near the opening and include discrete magnetic regions. A second plurality of magnetic regions can be disposed on the second sidewall near the access opening and include opposed discrete magnetic regions. The second plurality of magnetic regions being opposite the first plurality of magnetic regions. The discrete magnetic regions and the opposed discrete magnetic regions can be magnetically engageable with a magnetic force to close the opening of the package in a configuration having M petals, where M is an integer from 2 to 8.
