[Data] Measurement of the birefringence of laminate film

Explaining the effects of combining PET and EVA! Introducing measurement results using laminated film.

"Laminating film" is used in various industries to protect the display surface while maintaining the visibility of printed materials by using 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. [Contents] ■ Measurement of glass transition temperature by DSC ■ Birefringence measurement by WPA ■ Effects of combining PET and EVA *For more details, please refer to the PDF document or feel free to contact us.

[Data] Degradation Analysis of Polarizing Films and Light Diffusing Films

Introducing the usage samples along with their characteristics and the degradation analysis results of polarizing films and light diffusion films!

Polarizing films and light diffusion films are used in LCD products and design applications. They may deteriorate due to environmental conditions such as temperature and humidity, which can lead to a decline in their polarizing and diffusion properties, affecting LCD screens and designs. This document presents case studies analyzing the deterioration caused by temperature and humidity stress using FT-IR. [Contents] - Sample used and its properties - Deterioration analysis results of polarizing films (Comparison of IR spectra before and after testing at 70°C and 85% humidity for 1 week) - Deterioration analysis results of light diffusion films (Comparison of IR spectra before and after testing at 70°C and 85% humidity for 1 week) - Other available analytical methods *For more details, please refer to the PDF document or feel free to contact us.

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.

Optical film light transmission characteristics

We will consistently evaluate and analyze everything from material properties to the mechanisms of their functional expression!

At Aites Co., Ltd., we conduct "optical film analysis." Optical films used in smartphones and other devices have various functions depending on their structure and materials. We can investigate the transmission characteristics of anti-peeping films using angle-variable spectrophotometry and analyze the mechanism of function manifestation through cross-sectional observation and Raman analysis. 【Features】 ■ Measurement of optical properties ■ Analysis of the mechanism of function manifestation *For more details, please download the PDF or feel free to contact us.
