External Packet Inspection

External Packet Inspection

In modern packaging environments—especially FMCG, pharmaceuticals, and consumer goods—ensuring that each outer box contains the correct inner packets is crucial for both quality control and regulatory compliance. BT Print’s AI-powered External Packet Inspection System is designed to automate this complex verification process with unmatched speed and precision.

Using deep learning and high-resolution vision sensors, the system performs a comprehensive inspection of every outer box to detect:



  • Missing inner packets
  • Brand or SKU mismatches
  • Absence of mandatory excise stickers or labels


How the System Works:

  • As each outer carton or box moves along the conveyor, a vision camera captures the internal layout of its contents.
  • AI algorithms compare the captured image against a pre-trained model for the expected number, type, and arrangement of packets.
  • It then verifies:
    • oThe exact count of inner packets
    • The correct brand or SKU type
    • The presence and placement of excise or compliance stickers
  • If any discrepancies are found, the system instantly flags the error and triggers a rejection mechanism.


Key Features & Benefits:

  • High-speed detection of missing or mismatched packets inside cartons
  • Brand and SKU verification to prevent distribution errors
  • Reliable excise sticker presence detection on the box or packets
  • Works with transparent, opaque, or printed packaging
  • AI model can be retrained for different packet types, layouts, and packaging formats
  • Compatible with mono-brand or mixed-SKU boxes
  • Reduces manual verification efforts and packing errors
  • Enhances traceability and regulatory compliance in excise-controlled industries
  • Supports integration with existing conveyor systems and plant management software
  • Provides error analytics, trend reports, and rejection logs for line optimization


This inspection system is ideal for liquor distributors, food companies, and pharma exporters where packaging accuracy is critical to avoid financial loss, brand damage, or legal penalties.
