Why is the removable scratch proof aluminum sheet protective film made of polyethylene?

In the process of industrial manufacturing and transportation, the protection of the aluminum sheet surface is a very important part. In order to ensure that the aluminum sheet is not damaged during processing, transportation, storage and installation, a protective film is usually covered on its surface. Removable scratch proof aluminum sheet protective film is widely used in construction, electronics, automobiles and other fields. It can effectively prevent surface scratches and can be easily removed without leaving residual glue. Polyethylene is the main material of the protective film. Its unique physical and chemical properties make it the first choice for making scratch-proof protective films. The following will explore why polyethylene materials are widely used in the production of removable scratch-proof aluminum sheet protective films.

1. Polyethylene is a material with extremely high flexibility and durability, which allows it to fit well when covering the surface of the aluminum sheet and will not be damaged due to surface unevenness or external forces. At the same time, the polyethylene film can maintain its stable structure during long-term use and avoid cracking or deformation caused by material aging.

2. The surface of the polyethylene material is smooth and has good wear resistance, which means that it can effectively prevent damage to the aluminum sheet caused by slight friction or scratches. Especially during the handling or installation of aluminum plates, the polyethylene protective film can absorb external impact and friction, reducing the risk of surface damage. This feature makes it superior to other materials such as polypropylene (PP) or polyvinyl chloride (PVC) in terms of protective effect.

3. When aluminum plates are used in different environments, they may be exposed to various chemicals, including acids, alkalis or solvents. Polyethylene has good chemical corrosion resistance and can protect the surface of aluminum plates from pollutants in various harsh environments. For example, in the harsh environment of construction sites or industrial workshops, polyethylene protective film can prevent dust, oil and chemicals from invading aluminum plates.

4. Polyethylene also has excellent waterproof properties, which enables it to effectively prevent water or moisture from entering the surface of aluminum plates and avoid surface oxidation or corrosion. At the same time, polyethylene materials have good weather resistance and can resist the influence of natural environments such as ultraviolet rays, heat, and cold, ensuring that aluminum plates are still well protected when exposed to outdoor environments for a long time.

5. One of the most important functions of removable protective films is that they can be easily removed when needed without leaving residual glue on the surface of the aluminum plate. Due to its smooth surface, polyethylene material can work well with specially formulated adhesives, making the adhesion stable enough, but it will not tear or leave residue when removed. This feature is particularly suitable for applications with high surface requirements, such as home appliance housings, building exterior wall panels, etc.

6. The protective film made of polyethylene material can still maintain its good removability even if it adheres to the surface of the aluminum plate for a long time. This means that during the storage or transportation of the aluminum plate, even if it is exposed to sunlight or high temperature, the polyethylene protective film will not affect the tearing effect due to aging or hardening.

7. Polyethylene is a low-cost plastic material with mature production technology and can be mass-produced. Compared with other materials such as PVC or high molecular polymers, polyethylene is more competitive in price. Therefore, the aluminum plate protective film made of polyethylene material can provide good protection performance while reducing production costs. This is a significant advantage for enterprises producing in large quantities.

Due to the above advantages of polyethylene materials, in addition to being used for aluminum plate protective films, it is also widely used in other fields, such as surface protection of materials such as glass, plastic sheets, and stainless steel. Whether in construction, automobile manufacturing, home appliance production, or electronic equipment, polyethylene protective film can play an excellent protective role.
