Using microscopy to investigate packaging
Microscopy can aid the investigation of plastic and metal packaging material specification or allow in-depth analysis of defects or irregularities. Both types of packaging can experience a variety of defects.
For metal packaging these include issues such as external or internal corrosion, sulphur staining, pin holing and breaks in the lacquer/coatings.
Defects commonly associated with plastic packaging include issues such as faulty seals, delamination, perforations and pin holing.
Examination of defects and irregularities using microscopy allows the integrity of the packaging to be studied to establish if, and how, it has been compromised. Microscopy uses a range of techniques, including stereo microscopy, compound microscopy, scanning-electron microscopy (coupled with x-ray microanalysis and X-ray mapping) and Fourier Transform infrared (FTIR) spectroscopy to investigate plastic and metal packaging.
These tests complement our complete packaging analysis. It covers all forms of packaging and can harness additional techniques, including micro-CT scanner, dye penetration testing, pressure testing and migration testing. Get in touch to find out more.
