On the stage of modern industrial design, thinness, efficiency, and aesthetics have become core pursuits for products. When we marvel at the seamless integrated design of smartphones, the comfortable fit of wearable devices, and the stable operation of various precision electronic equipment, we often overlook a crucial “unsung hero”—ultra-thin flexible double-sided tape. Unlike traditional bulky connectors, this tape, with its extreme thinness, excellent flexibility, and strong adhesive force, is quietly transforming the entire manufacturing industry. It is no longer just a tool for connecting objects but a core material that enables more possibilities for products and drives design innovation. Its emergence allows designers to break free from the constraints of traditional fasteners like screws and rivets, combining various components in a more aesthetic, efficient, and lightweight way, thus creating the stunning products we see today. The core value of this tape lies in its ability to make products thinner and lighter without sacrificing structural strength and reliability, while providing unprecedented flexibility for complex internal space layouts.
