Non Residue. This security seal replaces the highly popular Type KN, it has a more aggressive adhesive, which makes it suitable for use on all surfaces. Initially developed for use as an Aviation Seal when aircraft 'Remain Over Night' but it can also be used 'In Flight' on doors or hatches that are not opened after each landing. In fact this security seal can be used in any application where no residue is a requirement. All three of the enhanced performance security seals, Types KR, KNR and KL are made from Mylar ®, an extremely strong polyester which is one of the most environmentally friendly polymer materials available. Basic colours are red or blue but there are eight differing colours available.
