Why vision inspection matters in pharma packaging
Pharmaceutical packaging must protect products from contamination, ensure accurate dosing,
and communicate essential information clearly. Even small defects — a misaligned label,
a damaged seal, an unreadable batch number — can compromise patient safety, trigger costly
product recalls, and cause regulatory action. Vision inspection provides automated,
100% inline inspection at production speed, catching every defect before products reach the market.
Key packaging inspection applications
🏷️
Label verification
Correct placement, legibility, and regulatory compliance of all label content — including language, warnings, and dosage information.
📊
Barcode and Data Matrix reading
Serialisation code accuracy and readability verified for full track-and-trace compliance with EU FMD and US DSCSA requirements.
🔒
Seal and closure inspection
Proper sealing detected in blister packs, bottles, vials, and syringes — ensuring product sterility is maintained through distribution.
🖨️
Print quality and expiry verification
Expiry dates, batch numbers, and dosage instructions confirmed present and legible on every unit before leaving the line.
📦
Component presence verification
All required packaging components confirmed in place — inserts, caps, safety seals, and secondary packaging elements.
Benefits of vision inspection
✓
100% inline inspection — consistent quality across every unit at full production speed
✓
Regulatory compliance — FDA, EMA, and GMP requirements met with full audit trail
✓
Reduced waste — defects identified early, minimising product loss and rework cost
✓
Full traceability — inspection data stored for audit, compliance, and continuous improvement
Rubber stopper inspection: ensuring sterility in injectable drugs
Rubber stoppers are a critical sealing component in pharmaceutical vials — preventing contamination
and maintaining the sterility of injectable drugs. Even the smallest defect in a stopper
can compromise product safety. Automated vision inspection ensures every stopper is perfect
before it reaches the filling line.
Common defects detected
Surface cuts, cracks & abrasions
Embedded particles & fibres
Flash and burrs from moulding
Dimensional out-of-spec variations
Deformation & surface damage
How it works — 5 steps
1
Feeding system — stoppers are fed onto a rotating inspection table or conveyor at production speed
2
Multi-angle cameras — high-resolution cameras capture images of each stopper from multiple angles simultaneously
3
Specialised lighting — bright field and dark field illumination reveals surface defects and embedded particles
4
AI image analysis — algorithms classify defects, identify acceptable units, and trigger automatic rejection of defective stoppers
5
Data logging — inspection data stored for GMP documentation, batch traceability, and regulatory audit
Benefits of automated rubber stopper inspection
✓
100% quality control — every stopper inspected, eliminating sampling errors and missed defects
✓
High-speed inspection — no slowing of production lines, inline with filling and assembly
✓
Full regulatory compliance — FDA, EMA, and GMP inspection documentation built in
✓
Reduced contamination risk — particles and seal failures caught before drugs are filled
✓
Cost savings — prevents waste and eliminates costly recalls from stopper-related failures
✓
Scalable — adapts to different stopper sizes, materials, and production volumes
