Not every closure failure is a stopper problem - sometimes the cap simply slips off the flange under pressure or repeated handling.
Our 30ml polypropylene pharmaceutical vial addresses that directly with a double retaining ring molded under the crimp flange, giving the aluminum cap two points of grip instead of one.

Purpose-Built for Bacteriostatic Water for Injection USP
30ml is not an arbitrary volume - it's the standard multi-dose fill size for Bacteriostatic Water for Injection USP, the diluent used to reconstitute powdered medications, peptides, and other injectable formulations across hospitals, pharmacies, and clinics. This vial was specified around that exact use case, and every dimension supports it.
30 mL Multiple Dose
BACTERIOSTATIC WATER
for Injection USP
FOR DRUG DILUENT USE ONLY
WARNING
NOT FOR USE IN NEONATES
Bacteriostatic water contains benzyl alcohol as a preservative, which means the vial has to be reopened and resealed multiple times over its use period without the cap loosening or the stopper losing its seal. That's exactly what the double retaining ring and the 20mm crimp finish are built to handle: the aluminum cap stays firmly seated crimp after crimp, and the natural translucent body lets pharmacy and clinical staff visually confirm the remaining fill volume before each draw - without needing to lift or unseal the vial to check.
Standard 30ml multi-dose format matches USP bacteriostatic water labeling and fill conventions
Double retaining ring keeps the crimp cap seated through repeated handling over the vial's full use period
Translucent body supports quick visual fill-level checks in fast-paced pharmacy and clinical settings
20mm neck finish accepts standard rubber stoppers rated for repeated needle withdrawal
Impact-resistant PP body reduces breakage risk during transport between pharmacy, clinic, and bedside

Why the Double Retaining Ring Matters
A standard single-ring crimp flange gives the aluminum cap one contact point to grip. Our double retaining ring design adds a second ring directly beneath the flange, distributing the crimping force across two points instead of one. The result is a cap that resists loosening under vibration, drops, and repeated handling - a meaningful difference for vials that travel through distribution and pass through multiple hands before use.

Crimp Finish or double ring Neck
The 20mm crimp finish is built for applications like bacteriostatic water that need a tamper-evident aluminum cap and a stopper rated for repeated needle withdrawal. For applications that don't require double ring crimp sealing, this same 30ml PP vial is also available with a standard crimp neck finish, closed with the same crimped aluminum ring.
20mm crimp finish
20mm double ring neck
Both neck options are molded on the same 32mm body / 66mm height format with the double retaining ring detail, so switching between crimp and double ring neck versions doesn't require a different case size or secondary packaging change.
Natural Translucent PP Construction
Content Visibility
The natural translucent finish allows fill level and liquid clarity to be checked without opening the vial.
Impact Resistance
PP construction resists cracking and shattering, an advantage over glass in high-handling environments.
Chemical Compatibility
Suitable for a wide range of pharmaceutical liquid and diluent formulations.
Standard 20mm Crimp Fit
Compatible with common aluminum and flip-off cap tooling already qualified for 20mm vials.
