Pre-packed cold sandwiches in a self-serve display are genuinely vulnerable to casual customer tampering because the display is unsupervised and some customers open containers to inspect contents. Tamper-evident packaging changes this dynamic because it makes any tampering visible to the next customer which creates a social deterrent. The SafePro TE24 24 oz tamper-evident container is sized correctly for sandwiches and wraps and the hinged one-piece design means there is no separate lid to misplace during packing which speeds the packaging operation considerably compared to two-piece containers. The tear strip is clearly visible from the front of the display case which is where the customer looks first when evaluating whether a package is intact. Case pricing and container specs at https://www.mcdonaldpaper.com/p/safepro-te24-24-oz-tamper-evident-clear-plastic-container-with-hinged-lid-200-cs.html and at 200 per case the economics work for an active grab-and-go program.
