The microfocus X‐ray beamline at the European Synchrotron Radiation Facility has been used to investigate the variation in molecular orientation and crystallinity in the wall of a container fabricated from poly(ethylene terephthalate). Two‐dimensional wide‐angle X‐ray scattering patterns were recorded and displayed in real time as the specimen was tracked across the incident X‐ray beam enabling the measurement of textural changes to be made with a spatial resolution of ~2 μm.
