pHoton Timelock Envelope

pHoton™ Timelocks™ are made from 80gsm pHoton™ high purity 100% cotton un-buffered paper and have been designed to avoid the use of any adhesives to ensure the absolute safety of photographic negative masters that do not require frequent handling. They are meant for the long term storage of the most precious and sensitive of photographic archive material such as microfiche masters, where the utmost caution has to be taken against degradation from contact with potentially harmful elements such as adhesives that may in time react with the enclosed material. Eliminating the gluing process makes pHoton™

Timelocks™ safer and better value than conventional envelopes.
