Microtome section/ cross-sectional image

Cross section of films, moulded forms, sealed seams etc., thickness determination of visible layers included,with reflected or transmitted light microscope (accredited test method).

In short — AI-generated

This test involves creating an ultra-thin cross-sectional slice of a packaging material, such as a film or a sealed seam, using a microtome. The sample is then examined under a microscope using reflected or transmitted light to visualize the individual layers of the material structure.

The resulting images allow for the precise measurement of individual layer thicknesses and the visual inspection of seal integrity. This data is used by developers to verify that the packaging construction meets technical specifications and to analyze the quality of sealing processes.
