Produced via the ionic liquid process (latest eco‑friendly technology): pulp is dissolved in AmimCl at 60‑80°C within 30‑45 minutes, then cast into a water/ethanol coagulating bath. The regenerated film is washed, dried, and wound. Solvent recovery exceeds 99%. The resulting cellophane has high strength, excellent transparency, and no residual solvents, making it ideal for sensitive pharmaceutical applications.
