1. An anti-tamper mailing bag comprising:
an electrical shield comprising a conductive pattern design on a substrate of the mailing bag, the conductive pattern design varying in at least one of form or density, wherein the conductive pattern design provides a unique electronically measurable signature based at least in part on the conductive pattern design of the electrical shield; and
monitoring electronics in communication with the electrical shield and configured to:
electronically measure the signature of the electrical shield;
store the signature of the electrical shield; and
detect a tampering status of the mailing bag based on a subsequent measurement of the signature of the electrical shield.
