Temperature: the first element of the film, the adhesive used in thermal lamination film is EVA hot melt adhesive, temperature determines the melting state of EVA hot melt adhesive, leveling performance, crystallinity and so on. Correct control of the temperature and range can make EVA hot melt and cure in time after composite, so that the surface of the coated product is smooth, no bubbles, no creases. According to our practice, it is more appropriate to control the temperature in the range of 80~110℃, and different thermal lamination film with different materials need to be tested.
Pressure: In the correct control of the temperature at the same time to give a certain pressure, can make the coating product itself to achieve flat and squeeze the surface of the air, to achieve EVA hot melt adhesive on the full surface of the complete coverage of printed matter, has good adhesion, and has a strong resistance to a variety of physical stripping, impact and other effects.
Speed: Thermal lamination film is laminating machine laminating, is a dynamic composite movement, laminating machine laminating speed determines the working time of the laminating product in the hot pressing process, also determines the laminating machine input temperature, pressure, etc. Both to ensure the speed of production and to achieve the desired laminating effect, it is necessary to find a balance between the temperature, pressure and speed, by fixing the temperature and pressure, adjust the speed to try, if the running speed is too fast, the bond is not strong, there will be fog, too slow is inefficient, and even bad products such as foaming.
The actual action value of the three factors of temperature, pressure and speed has a certain range, due to the difference in equipment, which requires us to find the best action value in practice to ensure the composite effect of thermal lamination film. If you buy our thermal lamination film, we will debug for you, solve the technical problems on the film, to ensure the normal use of thermal lamination film.
