As a result of the Tylenol Crisis of 1982 the FDA implemented regulations for manufacturers of medicines, food and other products, to use induction sealing and other methods to help provide evidence of tampering.
Some of these methods include break-away components which cannot be reattached, customs seals, tapes, labels, RFID (Radio-frequency identification) tags, blister packs, etc.
Packaging that tears open raggedly or cannot be resealed is sometimes used to assist in identifying that a package has been tampered with. Often multiple layers are used because no single layer or device is 'tamper-proof'. Unique custom indicators need to be changed regularly because they may become subject to counterfeiting.
Consumers and end-users need to be aware that they should watch for signs of tampering both at the primary means of entry and at secondary or 'back door' locations on a package.
