Description

Technical Field

[0001] The utility model relates to the technical field of gluing devices, in particular to a layered gluing device for PET release films. Background Art

[0002] Release liner is a thin film material coated with a special chemical (usually silicone oil or other low-energy surface agent) that prevents other materials from adhering to it. This property makes release liner very useful in a variety of industrial applications, especially where adhesion prevention or easy peeling is required.

[0003] The main purpose of gluing a release film is to provide a surface that can be easily separated after contact with another material without leaving any adhesion or causing damage. However, the gluing device in the prior art does not apply the glue evenly and cannot ensure that the thickness of the glue on the release film is consistent after gluing, which affects the use effect. PET release film usually needs to go through a drying process after gluing. The drying process helps to remove the solvent or moisture in the adhesive, so that the adhesive is transformed from a liquid or semi-solid state to a solid state and forms a strong bond with the PET film. Therefore, a PET release film layered gluing device is needed to solve the above problems. Utility Model Content
