How to distinguish between tactile film and tactile paper? In short, the tactile film can achieve the same tactile effect as the tactile paper after being adhered to it; But in terms of adaptability and characteristics to functions, it can bring more effects, while tactile films are relatively simple in terms of functions and effects.
In the application of tactile film, hot pressing and water-based adhesive coating are used to dry and then adhere the new tactile film to the appearance of the paper, achieving a special touch of lubrication, high transparency, and ensuring no blind spots after adhesion. This skill is applicable to luxury packaging boxes, high-end book covers, branded paper products, etc. But if the adhesion cannot affect the bonding effect of the tactile film, it will affect the overall effect. Just like the phone film, first of all, it is necessary to ensure that there is no dust on the film. Secondly, it is necessary to ensure that there is no air in the center, ensure overall adhesion, ensure that there are no blind spots in the center, and then ensure long use time. Some films fall off in just a few days due to their stickiness, and the quality of such films is useless.
However, the factors that affect the stickiness of the tactile film are generally divided into wetting and wetting:
Humidity: The appearance of wet tactile film and adhesive. Because humidity can prevent the occurrence of future central blind spots, as long as the pressure sensitive adhesive maintains good humidity when in contact with the surface of the adhesive, it can complete close contact, creating conditions for physical and chemical bonding. Molecular movement and dispersion: pressure sensitive adhesive molecules move to the surface of the adhesive. When the gap between two bonds is less than 5A, physical and chemical binding occurs. This method of combining physics and chemistry not only has good results, but also takes a long time.
2、 Immersion: Through the movement of the adhesive layer, under a certain pressure, the adhesive layer is immersed into the grooves and gaps, increasing the contact area between the two. At this point, mechanical bonding force is generated between the adhesive and the adhered material. Industry insiders know that the concave-convex bonding method is more robust, but it is less prone to damage and viscosity failure due to an increase in contact area.
