PU adhesive PET protective films are widely used for protecting delicate surfaces like electronic devices, automotive parts, and industrial machinery. However, over time, some users may notice a decline in adhesion strength. Why does this happen, and how can you avoid it?PU 粘合 PET 保护膜广泛用于保护电子设备、汽车零部件和工业机械等精密表面。然而，随着时间的推移，一些用户可能会注意到粘合强度下降。为什么会发生这种情况？如何避免？
There are several factors that contribute to the loss of adhesion in PU adhesive PET protective films. Exposure to extreme temperatures, UV light, humidity, and improper storage conditions can all negatively impact the adhesive quality. Additionally, prolonged use may lead to natural degradation of the adhesive properties, resulting in reduced performance.有多种因素会导致 PU 粘合 PET 保护膜失去粘合力。暴露在极端温度、紫外线、湿度和不适当的储存条件下都会对粘合剂质量产生负面影响。此外，长时间使用可能会导致粘合剂性能自然下降，从而导致性能下降。
