I am looking for a black light tight paper to store individually cut control strips in. Fuji control strips are already sold in packs of 10 wrapped into it. The same (similar?) paper is used for packaging Kodak 4x5 sheets of Ektar or Portra.
Can't find where I can buy some. Maybe I'm using the wrong keywords? An alternative is to find small light tight photo grade plastic bags similar to Ilford 4x5 or 100ft roll packaging.
if you are friendly with a movie lab and only need a few, they often have extras, as they would not normally put processed film into a black bag, preferring a clear bag .....
