Technical library
Make the next capsule decision with better context
Selection guides, qualification checklists and technical references organized for procurement, QA and formulation teams.
Featured selection guide
HPMC, pullulan or bovine gelatin?
Start with the formulation constraint that matters most, then confirm the supporting product and certificate route.
- HPMC: low-moisture plant-based starting point
- Pullulan: high clarity for selected clean-label products
- Bovine gelatin: conventional filling performance with source verification

Selection and qualification resources
Each resource connects to a product, document or request path; there are no dead preview actions.
Material-selection guide
Review source, moisture profile, release behavior, appearance and certificate route.
Supplier qualification checklist
Documents procurement and QA should request before approval.
Capsule size and capacity reference
Use nominal size as a starting point; actual fill weight depends on formulation density.
Moisture-sensitive formulation route
Review shell moisture, storage, transport and fill-material compatibility.
Halal certificate verification
Check issuer, scope, product, site, validity and destination-market status.
Procurement + QA
Supplier qualification checklist
Product definition
Material, size, color, print, release type and intended application.
Manufacturing site
Legal site name, location and relevant quality-system evidence.
Certificate scope
Issuer, product, site, activities, dates and target-market state.
Batch package
Specification, representative COA and shipment-document process.
Formulation reference
Capsule size starting points
Nominal sizes support early planning; confirm actual capacity with formulation bulk density and filling trials.
| Size | Relative capacity | Typical starting use |
|---|---|---|
| 00 | Largest listed option | Higher-volume powder fills |
| 0 | High | Common supplement starting point |
| 1 | Medium | Moderate fill volume |
| 2 | Lower | Smaller dose or denser fill |
| 3 | Compact | Low-volume formulations |

Product and document questions
How do I choose capsule size?
Start with target fill weight and bulk density, then confirm machine tooling and formulation behavior through testing.
Can I request a COA before ordering?
A representative COA may be available after company and purpose review. The actual shipment should receive batch-specific documentation.
Are custom colors and printing available?
Availability depends on material, colorant review, print requirement, MOQ and production feasibility.
How should capsule documents be maintained?
Each file needs an accountable owner, version, language, release date, review cadence and archival rule.
