From R&D to Commercialization: Tackling the Challenges of ODF Process Scale-Up
Share
Oral dissolvable films (ODFs) have emerged as an innovative dosage form, but moving from lab-scale R&D to commercial-scale production requires overcoming significant hurdles. Ensuring process consistency and data comparability across each stage is one of the biggest challenges for regulatory approval and market entry.
Why Is Process Scale-Up So Challenging?
- Equipment differences: Lab models and commercial-scale machines vary greatly, making data hard to compare.
- Parameter inconsistency: Coating thickness, drying conditions, and cutting methods may differ between systems.
- Regulatory requirements: Drug registration demands proof of process continuity and stability; gaps can lead to revalidation or even failure.
Common Industry Pain Points
- Repeated validation: Lab-scale data is often not accepted, forcing revalidation at pilot and commercial stages.
- Increased cost and timelines: Repeated trials extend development cycles and raise costs.
- Process risks: Film quality may become unstable after scale-up, resulting in batch rejections.
HUANGHAI’s Solutions
- Consistent process design: Whether using the MJ150-L or MJ150, the coating and drying logic remains the same, ensuring data comparability.
- Pilot-scale bridge: The MJ150-L acts as a pilot unit, creating a smooth transition between lab research and full-scale production.
- Same process logic across scales: formulation and process parameters developed on the MJ150-L carry over to the MJ150.
- End-stage integration: The MJ180 cutting & packaging machine ensures accurate dosing and stable packaging for compliant ODF products.
Compliance and Quality Value
- Improves data continuity to support drug registration and GMP audits.
- Reduces risk from process discrepancies.
- Accelerates time-to-market, increasing commercialization success rates.

Frequently Asked Questions
What is the difference between an ODF film and a transdermal patch?
Oral dissolving films (ODF) dissolve on or under the tongue within seconds to minutes; transdermal patches stick to the skin and release the API over hours to days. Both are made by solvent-cast film coating, and the MJ Pro coating platform can be built for either — the application is set before the machine is manufactured.
What output can I expect from Huanghai ODF machines?
MJ150-RD about 1,200 films per hour for formulation screening; MJ150-Lab 8,000–10,000 films per hour for pilot-scale work; MJ150 about 30,000 films per hour (Gen I) for commercial production. For packaging, the MJ180 cuts and packs about 11,900 films per hour (Gen I); the EZ320 (about 9,000 films per hour) is for food-grade films only.
What drying technology is used?
The MJ150 production line uses a patented hot-air parallel-flow drying tunnel (Academician Hou Huimin's patent CN201668734U). The MJ150-RD uses oven drying; the MJ150-Lab uses the same hot-air drying process as the MJ150.
Can Huanghai machines coat multi-formula (striped) films?
Yes. Huanghai's patent CN117323228A covers stripe coating that applies two formulations side by side in one pass, useful for fixed-dose combination films.
