Case study of fish-eye analysis of laminate film.
It has been determined that the cause is due to cured ink adhering to the printed surface of the printed PET film!
We will introduce a case study of fish-eye analysis of laminate film. In the multi-layer laminate film used for containers such as refillable shampoos, parts resembling foreign substances were observed. Upon magnified observation, they appeared to be several tens of micrometers in diameter and looked like fish eyes. To clarify the cause, cross-sectional observation was conducted. There are various methods for preparing cross-sections, but we implemented a mechanical polishing method that allows for extensive observation. 【Case Overview】 ■ Background: Discovered parts that appear to be foreign substances in the multi-layer laminate film ■ Purpose: Conducted cross-sectional observation to clarify the cause ■ Cross-section preparation method: Implemented a mechanical polishing method that allows for extensive observation *For more details, please refer to the PDF document or feel free to contact us.
