Identification of packaging materials

This article gives an outline of methodologies utilised in material identification of multilayer polymer films. The application of Differential Scanning Calorimetry, IR-Spectroscopy, Raman-Spectroscopy and microscopic investigations in material identification as well as their analytical limitations are discussed. Especially the non-destructive methodology of Raman-Spectroscopy is a promising future technology. However, only the combination of multiple techniques provides comprehensive details on different analytical issues such as quality assurance or defect characterisation.
