Advanced Closure Systems for Sterile Pharmaceutical Packaging
Zhengzhou PharGlass presents a premium line of Aluminum-Plastic Combination Caps, engineered to meet the rigorous demands of modern parenteral drug delivery. Just as top-tier glass vials require precision engineering, the closure system is the critical “second barrier” ensuring sterility from the manufacturing line to the point of care.
Our caps are designed to compete with global standards (DIN/ISO), offering a robust solution for sealing injection vials, antibiotic bottles, and biological reagents.
🚀 Technical Superiority & Material Science
Unlike standard closures, our Aluminum-Plastic Caps utilize a composite material strategy to balance security with usability.
- Hybrid Material Engineering (Aluminum + Plastic):
- The Aluminum Shell (Body): Provides the mechanical strength required for the Crimp Closure process. It creates a permanent, tamper-evident seal that withstands internal pressure and external shock during logistics.
- The Plastic Top (Flip-off): Designed with high-grade polymer for smooth tear-off performance. It protects the rubber stopper’s integrity and prevents dust accumulation (Anti-Dust feature) before use.
- Hermetic Sealing & Non-Spill Technology:
- The cap features a precision-molded inner skirt that grips the vial neck. When crimped, it exerts uniform radial force on the rubber stopper, preventing “micro-leakage” and ensuring a Non-Spill environment even under vacuum or pressure changes.
- Industry Context: Similar to the sealing integrity required by Schott AG for their premium vials, our caps maintain the Container Closure Integrity (CCI) essential for liquid and lyophilized drugs.

💡 Application Scenarios & Compatibility
Our caps are not just “bottle accessories”; they are an integral part of the drug delivery ecosystem.
- Pharmaceuticals: Ideal for sealing injectable solutions, vaccines, and antibiotics.
- Biotechnology: Compatible with sensitive biological reagents requiring strict moisture and oxygen barriers.
- Industrial Use: Suitable for high-value reagents and diagnostic samples.
Technical Note: O 13mm size is typically used for smaller volume vials (2ml-10ml), while the 20mm size is the industry standard for larger volume vials (10ml-100ml+). Both sizes are engineered to fit standard flange necks found on borosilicate glass vials.
🏭 OEM/ODM & Customization Capabilities
Em Zhengzhou PharGlass, we offer professional OEM/ODM services to align with your brand identity.
- Custom Colors: The plastic component can be customized (e.g., Blue, Red, Green, Yellow) to differentiate dosages or drug types (Color-Coding Safety).
- Logo Printing: We utilize advanced Silk Screen Printing technology to apply your logo or batch codes directly onto the aluminum shell. This ink is cured to resist abrasion and chemical exposure.
📦 Packaging & Logistics
- Packaging: Securely packed in cartons (48x36x36 cm) to prevent deformation during transit.
- Weight: Efficient gross weight (0.030 kg per batch unit) optimizes shipping costs for international logistics.
- Quality Control: Produced in Shandong, adhering to strict industrial standards to ensure every cap is free of burrs and sharp edges.
Choose Zhengzhou PharGlass for closures that don’t just cover the bottle, but protect the science inside.
