Why is the sealing tape aging? Production of transparent sealing tape

The tape will age after being used for a long time, so let's follow the production of our transparent sealing tape to understand the relevant cognition in terms of physical properties. The aging of the tape joint can be regarded as a change process in which the various properties of the tape are reduced under the influence of external physical conditions. The reasons for such problems mainly include chemical effects, physical effects and the reasons for their own materials. Generally, the surface of the tape ages faster than the interior. Among them, the physical effect means that under the influence of light and heat, the viscosity of the surface of the tape will decrease, and the speed of exposure to air will be faster. Humidity and heat are the most prominent problems that affect the durability of the tape.
