Inspection and Analysis of Foreign Matter Prevention of Defects in Packaging

Foreign matter can become mixed with food products during the production process for a variety of reasons. The discovery Testing the strength and functionality of packaging materials is essential to ensure food products reach consumers fresh and
and identification of foreign matter and ascertaining its source are essential for maintaining food safety. undamaged. To aid the development and quality control testing of packaging materials, Shimadzu analytical and testing
Shimadzu’s non-destructive testing and analytical technologies can be used to detect foreign matter that is not externally technologies allow the analysis of residual solvents in packaging materials, strength testing of adhesive seals, and checking of
