AI Technical Summary
Film-forming products are prone to wrinkling, deformation, and adhesion before reaching the target position, making it difficult to apply accurately and easy to disintegrate during use, thus affecting the effect of use.
The tensile strength of film products can be improved by setting a layered structure, including a combination design of functional film layers and sheets. The sheets can cover or be embedded on the surface of the functional film layer to provide support and isolation, delay liquid contact, and prevent rapid disintegration and deformation.
It improves the deformation and adhesion problems of film products when they do not reach the target position, ensures stable adhesion at the target position, and allows for multiple adjustments to the position, reducing usage costs.
