Scratch-induced damages on multi-layer polymeric packaging films are investigated using laser confocal microscopy. Films were tested using a modified version of the standardized linearly increasing load scratch test (ASTM D7027-05/ISO 19252:2008), which has been successfully demonstrated to correlate field data of commercial films with lab data. Scratch test results show clear distinction between the two model film systems on both the interior and exterior surfaces. Microscopy was performed to investigate the feasibility of utilizing this methodology as a tool for packaging film structure evaluation by determining the effect each layer has on the resistance of scratch damages. It is shown that the film exhibiting superior scratch performance also possesses significantly better stress distribution through its layers during the scratch test, as well as better layer adhesion during severe deformation. The scratch test is capable of discerning film mechanical integrity in a layer-by-layer fashion.
