Hot melt adhesive is applied on the film, how to choose the film coating machine?
Coating of hot melt adhesive on the film is a relatively common coating type recently. The film itself is relatively thin and soft. During the manual coating process, the coating effect may be affected due to the unevenness of the film and the inability to fix it. At this time, an automatic coating machine is needed for coating. The automatic coating machine can fix the film by vacuum adsorption, and it is designed for this kind of film substrate. The physical state of hot-melt adhesive changes with the change of temperature. During the coating process, it needs to be heated to melt the hot-melt adhesive to continue coating.
Coating of hot melt adhesive on film needs to be tested by using a heated air adsorption coating machine. The following is the test process of this four-in-one coating machine, and the test demonstration screen of hot melt adhesive coating on film.
Note: The general heating temperature of the laboratory coating machine is within 200°C, and the heating temperature should not be set too high. If the temperature is too high, the aluminum plate may be deformed.
