A tamper evident package includes a closure arrangement having a lockable orientation and an unlockable orientation. The lockable orientation includes a first closure member secured to a first package wall, and a second closure member secured to a second package wall. Preferably, the first closure member is secured to the first wall with a peelable sealing arrangement. The unlockable orientation includes the first closure member being separated or peeled from the first wall. The closure arrangement is transformed from the lockable orientation to the unlockable orientation in response to a pulling force separating the first closure member from the first wall. In some arrangements, the peelable sealing arrangement is pigmented to provide a visual indication that the package has been opened after an initial sealing of the closure arrangement. Methods for constructing and using a flexible package are provided herein.
