We offer a characterisation service for packaging films laminates and coextrusions. The techniques available include FTIR-ATR (diamond/germanium), DSC, microtome sectioning, optical and hot-stage microscopy.
These photographs show a multilayer plastic film structure in cross section, viewed under polarised light and a half-wave tint plate.
The individual layers were characterised using a combination of hot stage microscopy, differential scanning calorimetry and infra-red spectroscopy.
- Checking supplier delivery against specification
- Determining the structure of competitor films
- As part of an investigation into poor pack performance (e.g. shelf life)
