The material selection of printed screen stickers has a key impact on their fit with the screen, which is directly related to the product's use effect and user experience.
First of all, the common materials for printed screen stickers are PET (polyethylene terephthalate) films. PET has good flexibility and dimensional stability, its surface is smooth and flat, it can better accept printing ink, and present clear and bright patterns. In terms of fit, PET is relatively thin and soft, and can fit the screen surface tightly, especially for some curved screens, it can conform to the curvature of the screen and reduce the generation of bubbles and wrinkles. For example, PET is widely used in curved screen protective stickers for smartphones, which can protect the screen while maintaining good touch sensitivity and visual effects.
Secondly, silicone is also often used in the production of screen stickers. Silicone has unique softness and adsorption, and it can form a good fit when it comes into contact with the screen. Screen stickers made of silicone can effectively fill the slight unevenness on the screen surface, making the fit between the sticker and the screen tighter and preventing dust and water vapor from entering. Moreover, the friction of silicone material on the screen is moderate, and the sticker will not slip easily due to being too smooth, nor will it affect the touch operation of the screen due to excessive friction.
In addition, screen stickers made of tempered glass are also very popular in the market. Tempered glass has high hardness and strength, and can provide excellent scratch and wear protection for the screen. In terms of fit, it can be accurately attached to the screen through special process treatment, such as edge grinding and optimization of the bonding adhesive layer. However, since the tempered glass material is relatively hard, for some screens with large curved surfaces, the difficulty of fitting will increase relatively, and it is easy to have loose edge fit.
In addition, some new composite materials are gradually applied to the field of screen stickers. These composite materials combine the advantages of multiple materials, such as combining the flexibility of PET with the functionality of other materials, aiming to improve fit while giving screen stickers more features, such as anti-blue light, anti-peeping and other functions.
When choosing a printing material, you also need to consider the type of screen and the environment in which it is used. For device screens that are frequently used outdoors, it is necessary to select materials with good weather resistance to ensure that the fit and printing effect of screen stickers are not affected under different temperature, humidity and light conditions.
At the same time, the compatibility of printing process and material cannot be ignored. Different printing materials have different adsorption capacity and drying speed for ink. The appropriate printing process can ensure that the pattern is firmly attached to the material without affecting the fit performance of the material.
The selection of printing materials for printed products screen stickers needs to take into account many factors to achieve good fit with the screen and provide high-quality protection and decoration for electronic device screens.
