Multi-Formula ODF Coating Solution

Precision Multi-Formula Coating for ODFs — Powered by CN117323228A

HUANGHAI’s patented Slitting-Type Film Coating Device (CN117323228A) is a pharmaceutical-grade innovation designed to enable the simultaneous coating of multiple formulations on a single oral dissolvable film (ODF) base — ideal for combination therapies, fixed-dose regimens, and functional health products.

The Challenge in Multi-Formula ODF Production

Producing multi-API or layered oral films is inherently complex. Traditional methods often involve multiple coating runs or secondary shaping, which leads to:

  • Increased raw material waste
  • Inconsistent API dosage ratios
  • Higher energy and labor costs
  • Lower manufacturing yield and throughput

HUANGHAI’s Solution: Strip-Based Coating Innovation

Our patented system enables simultaneous slitting and coating of multiple film lanes in one continuous pass — streamlining production and preserving formulation integrity. Key features include:

  • Independent formulation channels with dedicated feed grooves
  • Adjustable strip width and layout based on target dosage
  • One-step transition from coating to cutting, without reshaping
  • Real-time control of strip dimensions and output parameters
The result: One film, multiple formulations, zero compromise.

Application Scenarios

This system is ideal for:

  • Fixed-dose combination (FDC) prescription drugs
  • Layer-sensitive or incompatible APIs
  • Custom release profiles within a single film
  • Precision nutraceuticals or cannabinoid formulations

Key Benefits

  • Save 20–30% in material loss via simultaneous coating
  • Preserve exact API ratios per lane/strip
  • Reduce equipment runs and downstream processing
  • GMP-compliant design, scalable to commercial volumes
