You're right about ORWO packaging. Soviet films however came without cassettes by default. I can't recall seeing any of those films coming with a cassette, although I can't rule out they might have in exceptional cases. Most of the Soviet films were loaded into used ORWO or Foma cassettes. Foma's metal cassettes were especially popular because of their ruggedness. ORWO also had thin aluminium canisters with plastic caps for their transparency films like UT18, those were also re-used in SU.
