TWO-SHEET:
MONO-SHEET: 
Working Principle Face the coated sides of L-Sheet and K-Sheet, apply pressure, the microcapsules of L-Sheet are broken,color forming material of L-Sheet reacts with color developing material of K-Sheet, red color appears. The damage degree of microcapsules is according to pressure level. The greater the pressure, the greater the damage of microcapsules and the higher the color density. On the other hand, the lower the color density.(1) Avoid direct sunlight ,away fire in original packaging. (2) Storage the film below 15℃. (3) Keep unused film in the black and blue poly sacks and store then in a box.| Product code | Width | Length | Pressure Range(Mpa) | Type |
