What are the factors that affect the peeling strength of composite membrane?

Effect of film surface treatment on peel strength. The surface tension of the film after surface treatment should be uniform, otherwise it will also have a certain impact on the peeling strength, resulting in uneven and inconsistent peeling strength. Effect of film surface cleanliness on peel strength. For some membrane materials that are easy to absorb moisture (such as nylon membrane), if moisture absorption has occurred, it will also affect the adhesion fastness of the extruded composite membrane. According to the research experience of Sanquan Zhong Shi, the combined pressure has little influence on the peeling strength, and the bonding between films is not tight, which will reduce the peeling strength. However, the composite pressure should not be too high, otherwise the film will be easily compressed and deformed.
