1.The adhesion of the adhesive is insufficient, and the adhesive remains sticky after being cured, resulting in a decrease in peeling strength.

2.The optical connection speed is slowed down, and the adhesion of the adhesive is reduced, which is easy to cause the foaming phenomenon of the composite membrane.

3.High temperature cooking film bag, in the high temperature cooking process the bag phenomenon increase.

4.The solvent evaporation is not complete, the compound film bag odor increase.

5.The solvent evaporation is not complete, the compound film bag odor increase.

6.The composite film hand felt more and more brittle.

In order to deal with this problems we must carry out targeted control in each process. Such as film, solvent, laminating environmental, adhesive, the process parameters of laminating machine etc. When we effectively control these processes, we can reduce the impact of high temperature and high humidity on the film.
