1. Mega Twister seals are etched with permanent laser marking. Laser marking offers the highest level of security as it cannot be removed and replaced.
2. The flap area is marked with sequential numbers, barcodes and/or text for security and easy identification.
3. Colour coding is possible via the combination of the white ABS flap and acetal twisters that come in a selection of colours.
4. Heat staking is used to permanently affix the twister to the seal body. Heat staked parts will leave clear evidence of tampering if the seal is cut or forced open.
