description: "A camera with even light over the line after the sealer takes a photo of each pouch or bag.

Flagged packs go to a reject or recheck lane, and each flag keeps its photo and time, so the line lead can link a run of bad seals to a jaw temperature, a film roll or a fill level and fix it early. The quality team checks samples each shift with the usual seal tests and decides what ships. The model does not replace leak tests, seal strength tests or food safety checks, which stay in place, and people make every quality and release call."

# How can a food or consumer goods packer use computer vision to check seals on pouches and bags?

A camera with even light over the line after the sealer takes a photo of each pouch or bag. A model trained on the packer own images, labeled against its own specs, marks likely seal problems such as wrinkles or pleats in the seal, product caught in the seal, seals that look narrow, crooked, burnt or incomplete, open corners and torn film, and it can also check that the zipper, tear notch and date code are present. Flagged packs go to a reject or recheck lane, and each flag keeps its photo and time, so the line lead can link a run of bad seals to a jaw temperature, a film roll or a fill level and fix it early. The quality team checks samples each shift with the usual seal tests and decides what ships. The model does not replace leak tests, seal strength tests or food safety checks, which stay in place, and people make every quality and release call.

## What this means in practice

- Start with one line and one pack size.
- Label photos from your own packs against your own seal specs.
- Use even lighting so wrinkles and gaps show clearly.
- Send flags to a recheck lane before using automatic rejects.
- Keep leak tests and seal strength tests in place.

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
