Technical Field

[0001] The utility model belongs to the technical field of release film processing, in particular to a pressing device for release film processing. Background Art

[0002] Release film is a thin film material with special properties. Its main feature is that it is non-sticky or only slightly sticky after contacting with specific materials under limited conditions. Release film is usually made by plasma treatment, fluorine treatment or silicone release agent coating on the surface of the plastic film to enhance the release force, so that it exhibits extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot melt adhesives, acrylic adhesives and rubber-based pressure-sensitive adhesives). Release film can be divided into many types according to different substrates, such as PE release film, PET release film, OPP release film and composite release film (compounded from two or more materials), etc. During its processing, a pressing device is required.
