Compared to regular aluminum-plastic flip-off caps, this cap has a thinner plastic cap portion and a longer aluminum ring portion. The extended aluminum cap results in higher capping quality when using capping pliers and automatic capping machines.
For pharmaceutical manufacturers, contract packagers, and sterile product suppliers, vial closures must balance regulatory compliance, production efficiency, and cost control
How OB Type A Outperforms Conventional Caps
The OB Type A cap redefines 20mm vial sealing through three intentional design upgrades, tailored to B2B needs:
Thinner Plastic Liner: Lightweight, Cost-Efficient, and Eco-Friendly
• 15% Thinner Than Standard Liners: Crafted from high-purity polypropylene (PP), the plastic inner layer is optimized for minimal material usage without compromising barrier properties (moisture/oxygen resistance).
• B2B Benefits: Reduces raw material costs by ~12% per 10,000 units; lowers carbon footprint for sustainable packaging goals.
• Performance: Maintains USP <87>/<88> Class VI biocompatibility for direct drug contact.
2. Extended Aluminum Height: Enhanced Stability and Sealing Precision
• 20% Taller Aluminum Body: The aluminum shell is elongated to reinforce structural rigidity, preventing deformation during high-speed capping (400+ vials/minute) or transit.
• B2B Benefits: Eliminates cap “wobble” in automated lines, reducing machine jams by 18% (pilot data with European CROs); ensures consistent seal compression for leak-proof integrity.
• Design: Smooth, scratch-resistant coating (Pantone-matched) with a subtle embossed logo for brand visibility.
3. Single-Use Tamper-Evident Design: Irreversible Security, Zero Reuse Risk
• B2B Benefits: Complies with FDA 21 CFR Part 211 (cGMP) and EU Falsified Medicines Directive (FMD); prevents counterfeit refills or contamination in 20mm antibiotic vials.
• User Experience: Easy “flip-off” mechanism for healthcare providers; no tools required.

Why B2B Clients Choose OB Type A
• Compliance Made Simple: Meets global pharma standards (cGMP, FMD) with full documentation (CoA, sterility reports).
• Efficiency Gains: Thinner liner + extended aluminum reduce material waste and machine downtime.
• Cost Control: Lower per-unit material costs + reduced recall risks (tamper evidence) = better ROI.
• Sustainability: Recyclable aluminum (90% post-consumer content) aligns with ESG goals.
