Application: A scratched or damaged original can spell disaster. In addition, oils from hands will do films and negatives no good. It is, therefore, standard practice to always keep originals and even dupes in protective sleeves both for handling and long-term storage. Crystal clear polyester or polypropylene sleeves allow viewing or inspection without removal and protect the image from dirt and scratches during handling and in storage Features: Film sleeves are available in archivally safe, clear 3 mil. Polypropylene or Polyester (Melinex 516 (Dupont’s replacement for Mylar D)), as shown. A self-locking side fold holds film in place. Sleeves “unlock” to open completely for safer film removal without sliding image inside the sleeve. Both materials, polypropylene and polyester, will not interact with film and prevent interaction between adjacent items in long-term storage. Choose Polypropylene for economy, or Polyester (“Mylar D”) if the very highest optical clarity is required)
