Electronic Device Packaging With High Barrier Film

With the rapid development of modern electronic information, people have put forward higher requirements for electronic components, moving towards portability and multifunctionality. This places higher demands on electronic device packaging materials, which need to have good insulation properties, protect them from external oxygen and water vapor corrosion, and have a certain strength, which requires the use of polymer barrier materials.
The barrier requirements for packaging materials in general electronic devices are that the water vapor transmission rate (WVTR) and oxygen transmission rate (OTR) should be less than 10-1g/m2/day and 1cm3/m2/day, respectively.
