[Data] Measurement of the birefringence of laminate film
アイテス
"Laminating film" is used in various industries for the purpose of protecting the display surface while maintaining the visibility of printed materials by utilizing highly transparent materials. During processing, heat bonding is performed, so it is assumed that the molecular state changes compared to before processing. In this study, we attempted to clarify the residual stress remaining in the product by comparing conditions with and without heat applied to the laminating film, using birefringence. This document presents measurement results using a laminating film composed of polyethylene terephthalate (PET) and ethylene-vinyl acetate (EVA) as an example.
