Due to FDA regulations , many manufacturers of food and medicine ( as well as other products ) now use induction sealing and other special means to help provide evidence of tampering . Break-away components which can not be reattached are useful . Custom seals , security tapes , labels , RFID tags , etc. are sometimes added
