Abstract

Tamper-evident features for containers. A tamper-evident film is target printed onto a sheet material that is thermoformable. The sheet is thermoformed into a container base or lid having a desired shape, such that the tamper-evident film is positioned in a desired area. A container lid is disposed on the container base, and heat sealed to a rim or edge of the container base. The heat sealing activates an adhesive of the tamper-evident film, and when the container lid is removed or separated from the container base, a first portion of the tamper-evident film remains on the container lid and a second portion remains on the container base. The separation of the tamper-evident film provides an indication of tampering.
