Four tips for quickly identifying composite films-film supplier

1. The composite film generally has natural curling phenomenon, which is more obvious if it is placed in hot water. 2. If the material of the innermost layer and the outermost layer of the composite film are different, the two sides of the film feel different, which can be distinguished by careful touch. 3. Cut a small cut on the film, and then slowly tear it diagonally. It is easy to separate the layers of the composite film composed of substrates with different tearing properties. 4. If it is a printed film, if the printed layer cannot be rubbed off, it means that the printed layer is sandwiched between two layers of film, and it is a composite film.
