Expertise in Privacy Films Since 2015
Established in 2015, Sewha specializes in the development and manufacturing of advanced privacy film solutions. Our core product is an optical film embedded with micro-louvers, designed to control viewing angles and effectively prevent visual data leakage, thereby safeguarding personal and confidential information.

Customizable Viewing Technology
Leveraging Sewha's proprietary technology (Sewha P&C), our privacy films allow for the precise selection of micro-louver density and exclusion angles to match specific user requirements. This customization ensures optimal privacy and viewing comfort for diverse applications and environments.

Health and Wellness Protection
Our films incorporate a blue light blocking feature to help reduce eye strain, minimize dryness, and mitigate potential sleep disruptions. Furthermore, all Sewha privacy filters are treated with a durable antibacterial coating that blocks over 99% of common harmful bacteria, including Staphylococcus, E. coli, and Pneumococcus, ensuring a cleaner and safer surface without compromising user safety.
