The polymer film base is the structural core of an oral dissolving film (ODF). It determines how the film behaves—its strength, flexibility, dissolution speed, stability, sensory feel, and compatibility with active ingredients.
At RSBM, our Polymer Film Base Systems are engineered using pharmaceutical-grade materials and validated across the entire ODF production chain, ensuring consistent, high-quality performance from formulation to mass production.
1. High-Purity Film-Forming Polymers
We select and optimize premium polymers based on your product’s technical requirements:
-
HPMC (Hydroxypropyl Methylcellulose) – excellent film strength and clarity
-
Pullulan – high transparency, smooth mouthfeel, fast dissolution
-
PVA (Polyvinyl Alcohol) – strong mechanical properties, stable drying behavior
-
Sodium Alginate & Pectin – natural/vegan positioning, flexible texture
-
Special hybrid polymer blends – for high-loading capacity or moisture-resistant films
Each polymer undergoes viscosity, compatibility, and stability testing to ensure predictable processing behavior.
2. Tailored Mechanical & Sensory Performance
Different applications require different properties. We adjust polymer ratios and additives to achieve:
-
Controlled flexibility (anti-brittle performance)
-
Smooth mouthfeel suitable for pharmaceutical and consumer health products
-
High tensile strength for films requiring strong handling or packaging resistance
-
Ultra-fast or controlled dissolution depending on product positioning
-
Neutral taste systems to support flavor masking and premium user experience
3. High-Loading Polymer Matrix Options
For formulas containing caffeine, nicotine, herbal extracts, probiotics, collagen, NAD+, or minerals, we offer high-loading polymer base systems that maintain structural integrity even with increased active ingredient levels.
This allows thin films to deliver potent dosages without cracking, sticking, or uneven drying.
4. Optimized Drying & Casting Performance
RSBM’s polymer bases are designed to work seamlessly with our casting and drying equipment:
-
Stable viscosity under different temperatures
-
Even flow during casting
-
Controlled shrinkage during drying
-
Minimal curling or deformation
-
Excellent compatibility with slitting and cutting modules
This synergy reduces waste and ensures batch-to-batch consistency.
5. Clean-Label & Market-Specific Options
For brands targeting specific regulatory or marketing demands, we offer:
-
Vegan & natural polymer systems
-
Sugar-free formulations
-
Non-GMO / allergen-free materials
-
Child-safe, pet-safe, and food-grade options
These systems ensure compliance across global markets including the U.S., EU, Southeast Asia, and the Middle East.
6. Fully Integrated With RSBM’s Full-Chain ODF System
Your polymer film base is validated through the entire production chain:
Formulation → Casting → Drying → Slitting → Cutting → Packaging → Stability Testing
This guarantees smooth scale-up from pilot to mass production, with no unexpected behavior during manufacturing.
