Photo film is manufactured in rolls and sheets.
The sizes of film are agreed with a customer.
Thickness of base are ranged 175 ± 5, 190 ± 5 micrometers.
Open and process the photographic films under indirect safe light conditions with using a dark-red light-filter № 107 for VRP, VRP-M, PFG-04 photographic films, and with using a dark-green light-filter № 170 for PFG-01, PFG-03M photographic films, and for PFG-03C photographic film with using light-filter № 107 and № 170.
Climate conditions for photographic films usage: temperature of environment is (20 ± 5)оС, relative humidity of air (65 ± 15)оС.
Guaranteed Shelf Life Of Photo Films:
— in rolls — 18 months.
— in sheets: VRP, VRP-M, PFG-01, PFG-04 — 12 months.
— PFG-03M, PFG- 03C — 6 months.
