Tray and sleeve inspection for complete retail packs

Inspection overview

Inspect the pack after sealing and sleeving

Trays can carry reflective film, textured food, clear lids and printed sleeves that hide different areas of the pack. Inspection points should therefore be considered before and after sleeve application so the seal and presentation checks each have a clear view.

Oxford Vision Systems can integrate cameras with tray sealers, sleevers, labellers, conveyors and downstream reject equipment. Results can be stored or passed to line controls for production monitoring and fault response.

Checks that can be combined

The final inspection set is selected from the visible features, risk, product presentation and achievable image resolution.

• Tray presence, orientation and profile
• Visible lidding-film and seal-edge condition
• Product or contamination at the tray rim
• Sleeve presence, alignment and correct variant
• Label presence, position and identity
• Date and lot code verification
• Barcode and 2D code reading
• Damaged, open or deformed pack detection

Application details we review

Early clarity on these points helps avoid false rejects, blind spots and mechanical changes late in the project.

• Clear, printed or reflective lidding film
• Tray rim visibility and food presentation
• Sleeve coverage before and after application
• Wet, chilled or condensation-prone packs
• Under-tray label or code location
• Reject handling without pack damage

Keep seal and sleeve checks visible

We identify which features disappear after sleeving and position the inspection stages accordingly, with tracking between them where required.

Feasibility work establishes the camera view, lens, light, exposure and image-processing approach. We then define the enclosure, conveyor changes, controls, operator interface and rejection needed for production.
