What is a pressure sensitive sticker?
There are two types of pressure sensitive stickers, one-piece type and two-piece type.
The two-piece type is composed of two layers, which are a microparticle layer with a color-developing material and a color-forming layer. The monolithic type also has both layers.
Working principle of pressure sensitive stickers
When subjected to pressure, the micro-particles rupture and react with the color-forming layer. The red spots appear on the test paper. By adjusting the rupture of microparticles under different pressures, pressure values in a wide range of pressures can be obtained.
