Inspect every tray
Move from intermittent sampling to repeatable in-line inspection.
Tray-seal inspection
Inspect lidding film and tray seals without slowing production
Verify seal coverage, lidding-film presence and critical seal-edge defects on every tray before sleeving, cartoning or case packing.
The inspection challenge
Inspect the complete tray perimeter—not a sample from the batch
Tray sealing faults may be intermittent and difficult to catch through manual sampling. Multi-camera layouts and purpose-designed lighting can keep the full seal region visible despite reflective film, print and changing product presentation.
- Missing lidding-film detection
- Misaligned or short film checks
- Contamination across the seal path
- Folded and wrinkled edge detection
- Tray presence and orientation checks
- Downstream reject and verification
Production outcomes
Designed to make every decision useful
Protect downstream equipment
Remove visibly failed packs before sleeves, labels or cases add cost.
Handle multiple formats
Store validated recipes for different tray, film and product combinations.
Application framework
What the system can include
Final scope follows trials and a line survey. The table shows the main engineering considerations for this inspection type.
Send us your pack detailsSuitable linesSingle- or multi-lane tray sealers, continuous conveyors and indexed systems
Typical faultsNo film, film shift, folds, wrinkles, seal contamination and damaged edges
OpticsArea-scan cameras, polarised or diffuse lighting and multiple views where needed
ControlsSealer/PLC interface, product tracking, reject timing and line-stop options
A controlled route to production
From sample pack to validated inspection point
Reliable inspection begins with realistic defects and finishes with the line proving that the correct failed pack was removed.
Define the fault
Agree the pack, line speed, critical seal area and pass/fail tolerance.
Prove the image
Trial representative good packs, known failures and normal production variation.
Engineer the station
Specify handling, optics, lighting, controls, guarding and reject method.
Integrate & validate
Install, commission and test the complete inspection and rejection sequence.
Practical answers
Seal inspection questions
Clear answers before you invest in an in-line inspection project.
Can you inspect clear or highly reflective film?
Often yes. The key is optical design: camera angle, polarisation, wavelength and diffuse lighting are selected through trials using your actual materials.
Can one system inspect different tray sizes?
Yes, when the mechanical field of view and camera resolution cover the required range. Each format can have its own recipe and tolerances.
Can it check printed film as well as the seal?
The same station may also verify selected print, artwork, code or label features, subject to image resolution, line speed and the available views.
Application guidance
Plan tray inspection around the product, film and atmosphere
Ready meals, fresh food and MAP trays create different contamination, film and integrity questions.
