Identification of Packaging Structures

If you need to compare material specifications or investigate poor material performance, for example delamination of layers of a structure, we can assist with the necessary identification studies.

Packaging materials are often co-extruded multi-layered structures that are not easily separated into individual layers for characterisation.

Structure identification usually requires the use of a combination of analytical techniques.

How we can help:
Smithers Pira is uniquely placed to carry out complex analysis and investigation using a range of techniques.


Clients benefit from a troubleshooting approach which combines expertise on the physical testing of materials and primary packaging with advanced chemical analysis.

Techniques including: Optical microscopy, hot stage microscopy  Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) can be applied to establish the structure of the packaging.  

The results of the analysis can be summarised on coloured cross sectional annotated images with the identification of the polymer types and layer thicknesses.
