Inspecting Blister Packages


Blister packs and shrink-wrapped kits demand fast, repeatable checks of seal integrity, print quality, and contents. Variations in clear plastics, glare from lidding foils, and frequent changeovers make manual inspection inconsistent. Zebra machine vision standardizes these tasks using robust tools for measurement and print verification, and built‑in traceability. Lines catch defects earlier, cut waste, reduce recall risk, and maintain a searchable audit trail without slowing production.

Verify contents, print, and seal integrity in clear and foil‑lidded blister packages at production speed with documented, repeatable results

Automate seal and print inspection

Automated inspection confirms intact, uniform seals and legible printing. Zebra smart cameras pair with Aurora machine vision software to standardize inspection at production speed. Edge and texture analysis measure seal width and continuity, while area inspection detects wrinkles, voids, or contamination in the seal zone. Optical Character Recognition (OCR) validates lot and expiry data, and integrated code reading confirms barcodes. The system reduces false rejects, prevents escapes, and builds evidence for compliance.

Verify contents and alignment before and after sealing

Before sealing, presence/absence, counting, and position checks confirm that each cavity is filled correctly and that inserts or leaflets are in place. After sealing, tools verify seal continuity, package outline, and printed graphics, and they detect trapped debris at the seal edge. Aurora Design Assistant software triggers light stacks and reject mechanisms to route defective items to a reject bin, and logs fault codes for exception handling. It records accurate, real‑time results with timestamps for traceability and reports outcomes to a Manufacturing Execution System (MES) or PLC to speed root‑cause analysis and continuous improvement.
