Royal Bank of Scotland chooses Safeguard
The Royal Bank of Scotland has announced that the new 5- and 10-pound notes will be printed on the polymer substrate Durasafe Safeguard produced by De la Rue. [Edit: that's what you get when you first read a story about Durasafe and then write a post. To be clear: it's Safeguard, NOT Durasafe. Comment below is of course absolutely right].
Clydesdale Bank and Bank of Scotland are already making the transition and the Bank of England is to introduce the plastic notes from next year. The Royal Bank of Scotland said it was to re-design its notes with new subjects for portraits. The £5 note should be in circulation from the second half of 2016. The £10 note will be in use a year later. The polymer notes will be 15% smaller than the cotton paper variety circulating right now.
Durasafe is a product of Landqart Switzerland, not of De La Rue. Durasafe was already used on the Morocco 25 Dirham note. Durasafe is also a material making the note Hybrid, not Polymer.
