Mobile phone film:

First-generation PC film. Generally, films are made of pellets and are extruded or calendered like PC.

Second-generation PET film flat phone point-and-shoot type.

The imported third-generation ARM tape may be more expensive.

At present, in the mobile phone accessories market, the main materials for screen protectors are PVC (modified moderator), PET and ARM. As for the PP material that has appeared early, it relies entirely on glue to stick to the mobile phone screen due to its own adsorption force, and its service life is short. The products that tear off the screen and leave obvious traces of glue have now been eliminated.

The characteristics of PVC material protectors are soft and easy to apply. PVC material protectors are rough in workmanship and simple in packaging. They have poor scratch resistance and short service life. Generally, affordable mobile phones come with screen protectors made of PVC material! The old type PVC material protector peels off the PP material screen protector with glue and watermark. The material itself is thicker and the translucency affects the screen display effect. It also turns yellow due to temperature changes. There is no actual market demand! Be sure to buy it. Pay attention to buying products that have been eliminated and have overstocked products. Ping Yi Mo Cai is especially popular in the mobile phone accessories market. The improved version of the PVC material protector has the same tearing marks as the improved version of the PVC material protector. It solves the problem of the thickness and light transmittance of the material itself. The PVC material protector Only now do consumers agree that the improved PVC material protector has not completely solved the yellowing problem. If it is used for flip phones that support touch operations and affordable mobile phones with a thousand yuan level, it is believed that using the improved PVC material protector would be unsightly.

PET material.

PET material protectors are currently available on the market. Well-known brands of mobile phone manufacturers are randomly configured with PET material protectors. The workmanship and packaging of the PET material protectors are relatively exquisite, and they are specially designed to protect popular mobile phone models. If the sticker needs to be cut, use PET directly. The recycled material itself is relatively hard, the surface is highly resistant to friction and scratches, and it has high light transmittance (90%), anti-glare, and avoids dust adsorption. When used, PET may turn yellowish. The material sticker generally adopts an electrostatic adsorption design. No glue will fall off on the back of the film. Clean it with clean water for reuse. Currently, there are two types of PET material protective stickers on the market: double-layer design and three-layer design. PET low-viscosity application layer + PET peel-off layer three-layer design The low-adhesive protective film surface is added with two layers of high-level 1/2 labels. Different from supporting screen touch operation and full handwriting operation, mobile phones or high-priced straight-body machines and sliding cover machines use PET material protective stickers to choose ARM materials.

ARM screen protectors are currently the only screen protectors on the market. The surface has been treated with a special process and is softer, has strong anti-friction and scratch resistance, and has high light transmittance (95%). Reflective and other advantages, these special purpose anti-peeping screen stickers are expensive and cost hundreds of dollars. Mobile phone screen protectors are expensive and of high quality. Protective stickers are generally available in mobile phone accessory-type stores and are relatively rare in relatively small mobile phone retail dealerships/agents/chain stores. The ARM composite material itself is generally composed of three layers of materials. The outer layer is specially treated with "AG" treatment layer and "HC" treatment layer. The AG finger anti-glare treatment frosted protective film adopts this treatment and is suitable for supporting touch operations. Used with handwriting input mobile phones, HC finger hardness treatment, high transmittance type protective sticker, suitable for ordinary screen mobile phone interlayer, PET material surface, silicone composite layer used as adhesive, effectively prevents bubble-shaped tear marks, can be cleaned with water, reused due to ARM's own material protection The phone itself contains corrosive adhesives, which can cause harm. The material itself contains body-harming materials, which are safe. High-end mobile phone users say it is recommended to use ARM material screen protectors.

Things to consider when purchasing screen protectors.

Some unscrupulous merchants in the mobile phone accessories market use PET material protectors to pass off as ARM material protectors and sell them! In this case, even some stores in Hong Kong can earn a high price difference. Moreover, the screen protectors can be returned and exchanged after being torn off. It is recommended that buyers make a simple identification of the two materials when packaging in front of the store clerk. First, look at the material hardness of the sticker itself, which seems to be harder. The PET material protector and the ARM material protector are softer; although the PET material protectors are sold in two-layer and three-layer markets. The three protective overlays are all blue, and the protective overlay layer made of ARM material is blue. Some product manufacturers on the market process it by themselves. The product manufacturers first purchase some PET or ARM sheets, cut and package them by themselves, and then create brand packaging and print English or Chinese and other foreign language trademarks. Descriptions and other text pretend to be original imported screen protectors. The protectors are processed by the manufacturer themselves. The actual low price of the screen protector is quite profitable. Since screen protector brands are too difficult for users to identify, it is recommended that consumers pay attention to the brand when purchasing. Imported products should pay attention to their own manufacturing material problems, poor cutting technology, and reasonable prices. When purchasing screen protectors, first choose a custom-made protector based on the model of the phone. Choose according to the screen size of the mobile phone to avoid the need to cut it by hand. If so, it will be easier. Once the solution is perfect, some "mobile phone beauty shops" need to be closed.
