Precision matters in pharmaceutical packaging – choose the right glass bottle size for your needs.
Introduction
In the pharmaceutical and nutraceutical industries, selecting the right glass bottle size for capsules and pills is critical for product integrity, compliance, and user experience. This guide explores industry standards, design considerations, and Roetell’s expertise in manufacturing FDA-compliant glass containers tailored for solid dosage forms.
Why Glass Bottles Are the Preferred Choice for Pill Packaging
Science-Backed Advantages:
- Zero Chemical Interactions: Borosilicate glass prevents leaching (unlike plastics)
- Moisture Barrier: 100% impermeability protects hygroscopic medications
- UV Protection: Amber glass blocks 99% of UV light (critical for light-sensitive drugs)
- Sustainability: Infinitely recyclable with 30% lower carbon footprint than plastic alternatives
Roetell Insight: Our Type I glass bottles exceed USP <660> standards for hydrolytic resistance.
Understanding Capsule and Pill Sizes
Pharmaceutical Size Standards:
| Dosage Form | Common Sizes | Volume per Unit |
|---|---|---|
| Tablets | 6mm-20mm diameter | 0.5-5ml |
| Capsules | 000 (1.37ml) to 5 (0.13ml) | 0.13-1.37ml |
| Softgels | 3-22mm oval/round | 0.2-5ml |
Pro Tip: Always account for 15-20% headspace to prevent powder degradation from shaking.
Key Considerations When Choosing Glass Bottle Sizes
- Dosage Count:
- 30-day supply ≠ 30 pills (consider 2x daily doses)
- Pill Dimensions:
- Aspirin (325mg): 12mm dia. → 100ml bottle holds 50 tablets
- Fish Oil Softgel: 20mm long → Requires wide-mouth 60mm jar
- Closure Systems:
- Child-resistant (CR) caps add 10-15mm height
- Regulatory Compliance:
- USP <671> single-dose container requirements
