We will laminate functional films for touch panel displays with high quality.
At Sunny Sealing Co., Ltd., in addition to traditional double-sided tape and functional film processing (die-cutting and laminated composite processing), we are currently advancing the development of bonding technology. We address challenges such as bubbles, warping, foreign matter entrapment, and misalignment—issues that are difficult to resolve with just equipment and technology—through integrated production of "processing + bonding" and total technology.
