The techniques available include FTIR-ATR (diamond/germanium), DSC, microtome sectioning, optical and hot-stage microscopy.

These photographs below show a multilayer plastic film structure in cross section, viewed under polarized light and a half-wave tint plate:

The individual layers were characterized using a combination of hot stage microscopy, differential scanning calorimetry and infra-red spectroscopy.

Applications for this test include:

  • Checking supplier delivery against specification
  • Determining the structure of competitor films
  • As part of an investigation into poor pack performance (e.g. shelf life).
