Home / Tube Filling CDMO | Sterile Tube Filling Contract Manufacturing Services /
Sterile tubes are a key delivery format for ophthalmic ointments, dermatological creams, rectal gels, and other semi-solid or viscous sterile products. These products require aseptic filling, accurate dosing, and moisture- and contamination-resistant packaging. That’s why companies rely on specialized tube filling CDMO partners with infrastructure for sterile tube filling contract manufacturing.
From formulation and viscosity adjustment to aseptic fill-finish and labeling, these CDMOs deliver safe, consistent, and compliant sterile tube-based products across multiple therapeutic areas.
When selecting a tube filling CDMO, key considerations include:
Experience with semi-solid and ointment formulations
Aseptic or terminal sterilization filling processes
Support for aluminum, laminate, or plastic tubes
Tube volume flexibility (commonly 2 g – 100 g)
Automated filling and crimping equipment
Cold chain and light-sensitive product capabilities
Regulatory inspection readiness (FDA, EMA, PMDA)
Moisture and oxygen barrier handling for high-sensitivity actives
The right CDMO ensures sterility, product protection, and regulatory compliance across every batch.
Top-tier sterile tube filling contract manufacturing partners typically offer:
Formulation and viscosity optimization for smooth extrusion and patient application
Aseptic or sterile hot filling into tubes
Sealing and crimping (folded, ultrasonic, or heat-sealed closures)
Tube labeling and serialization
Sterility testing and container closure integrity testing (CCIT)
Compatibility testing for product–container interaction
Stability studies under ICH guidelines
Regulatory support and batch release documentation
These services are essential for ophthalmics, dermatology, women’s health, and topical sterile therapies.
Working with an expert tube filling CDMO offers key benefits:
Reduced contamination risk with fully enclosed filling systems
Greater patient safety for eye and wound care formulations
Precise dosing with customized tube designs
Improved shelf life using barrier tubes and advanced sealing
End-to-end support from formulation to packaged product
Tubes remain a preferred format for patient-administered sterile therapies due to convenience, safety, and portability.
