Innovative imaging technology easily detects seal contamination , even through printed films
Contamination in the seal of rigid packages causes important issues for food producers as it may lead to leakage and consequently reduced shelf life , health issues and even expensive recalls with potential brand damage . As such automatic detection of contaminated seals is important for both food safety and production automation . Engilico™ , specialist in in-line seal inspection for flexible packaging , now introduces its newly developed seal inspection solution for plastic or cardboard rigid trays , pots and thermoforms sealed with plastic film .
Hyperspectral imaging provides higher contrast and allows to detect different substances , even through printed film .
The new HyperScope™ solution is sealing issues may induce extra costs based on hyperspectral imaging ( HSI ). due to line stoppage , manual repackaging or machine cleaning . For
This technology enables to obtain images with much higher contrast inspection of flexible packages such as than traditional vision systems pouches , flow wraps and VFFS bags , and can even detect contamination Engilico already marketed SealScope™ , through printed films . Typical an in-line , 100 % seal inspection sensorbased solution for flexible packaging applications are the in-line inspection of trays with meat , such as pouches , flow-packs and cheese , fruits , ready meals , bags . But many – and often the same snacks , etc .

Product in seal often causes issues for standard vision systems , as there might be not enough contrast between the plastic film and the contamination . To increase contrast , traditional vision systems use opposite lightning , but this is not possible when using cardboard trays or backing materials , that are very popular as an ecological alternative to
