E Ink is dedicated to materials film research and development, and we manufacture and provide flexible substrate material, PI (Polyimide) and functional material films. Premium quality material and functional films enable smooth production process of ePaper display modules and modules of other technologies.
E Ink does material coating process development, manufacturing process development, and mass production quality control. We are ISO 9001:2015, ISO 14001:2015 certified.
PI (Polyimide) varnish can be used as flexible substrates, enabling flexible display mass production. PI varnish is offered to display manufacturers.
PI is offered in coated rolls, for use in the manufacturing process of flexible displays.

AG film is applied on ePaper displays to help achieve an anti-glare viewing experience.
Optically clear adhesives are used for touch display lamination.
Moisture barrier film helps prevent moisture from entering ePaper display modules.
Conductive Release Film is used during ePaper display conductivity tests.
