Hi All,

I have a question on optical grade BOPET film. Why is the reason why so many BOPET plants fail to meet the requirement for optical grade BOPET film (eg, Haze of less than 1.5%, ASTM D1003)? Is it due to the thermoforming process or quality control issue ?
I am referring mainly for the applications in touch panel display. Please advise...

regards,
