Abstract
A tamper-evident food delivery packaging systems, methods of tamper-evident packaging of food for delivery, and apparatus for tamper-evident food packaging operate to form resilient self-fastening perforations through a packaging. A binding apparatus includes an anvil and a flipper plate. A cutter head includes a profile blade and a slot blade. A pusher is pivotably connected between the profile blade and the slot blade. The cutting apparatus moves in a reciprocal motion relative to the anvil while the flipper plate engages a pusher to pivot the pusher during the reciprocal motion.
