Hyperspectral seal inspection system easily detects contamination in rigid plastic packaging, even through printed film

摘要

Belgian seal inspection specialist Engilico has introduced a new system for in-line verification of the integrity of hermetically sealed plastic rigid packaging containing food. In addition to the established SealScope™ automated system for seal quality control of flexible plastic packaging, the company has introduced a new system, HyperScope™, for checking the seals on rigid trays, pots and other thermoformed packages sealed with plastic film, even when printed. Product in seal often causes issues for standard vision systems, as there might not be enough contrast between the plastic film and the contamination. In case of packaging with a printed top film, often used for more luxury products, the contamination can even not be seen.
