Tamper Evident Packaging (TEP) is a broad category of packaging practices and technology that alerts the consumer of foul play or damage to the product during the B2C route. This is usually useful for international shipments or high-value local shipments that are delivered to the consumer through a third party. As opposed to Tamper Resistant Packaging, which is designed to be very hard to open, Tamper Evident Packaging provides a visual indication of tampering.
