3. The subsequent processing steps of the protective film are the key to determining its viscosity. Subsequent processing generally includes bending, stamping, cutting, drilling, hot forming and other processes;
4、保护膜的厚度与粘性进行合理搭配;
5、保护膜的拉伸强度和伸长率，从而以确保保护膜的柔韧性和强度能达到一定的要求;
6、保护膜选型的原则：进行充分测试。其中包括了解被粘帖材料的特性以及其他要求(使用环境、储运条件、户外要求、基材颜色、印刷与否)。
