A faulty seal ruins product preservation and compromises food safety. On heat-sealed trays and containers, a fold, product residue in the sealing area or a missing seal cause leaks and loss of vacuum. Heat-sealed container inspection with machine vision verifies the seal of every pack in-line. Let’s look at what it checks and how AIS Kariko solves it.
Why inspect the heat seal
Heat sealing guarantees tightness and product shelf life. If the seal fails, the pack loses hermeticity and the product spoils early. In food it is also a matter of safety and compliance with food contact materials regulations.
What defects machine vision detects
A heat-seal inspection system detects: missing seal, incomplete or irregular seal, product or dirt in the sealing area (which prevents a proper seal), and folds and wrinkles in the film. Every defective tray is rejected automatically.
How it works
With the right lighting and software, machine vision “sees” the sealing area and evaluates it unit by unit, at line speed. This prevents a poorly sealed pack from continuing to palletising and the market.
AIS Kariko: heat-seal control
AIS Kariko is our heat-sealing control system: it inspects the sealing area of trays and containers, detects faulty seals and separates affected units, integrating with your line and reject system.
