PROTECTIVE FILMS

The Necessity of Applying Protective Film on Aluminum Profiles and Plates

Dec. 25, 2024

Applying protective film on aluminum profiles and plates is essential for several reasons. Aluminum is a widely used material in various industries due to its excellent properties such as strength, durability, and corrosion resistance. However, during manufacturing, transportation, and installation processes, aluminum surfaces are susceptible to damage from scratches, abrasions, stains, and other forms of contamination. Protective film serves as a temporary barrier, safeguarding the integrity and appearance of aluminum surfaces until they reach their final destination. This article explores the necessity of applying protective film on aluminum profiles and plates in more detail.

 

Overview of Protective Film and Protective Film for Aluminum Profile


The protective film is one kind of film material with a surface protection function, and it is also one of the most important products in pressure sensitive adhesives (PSA).The protective film is usually made of polyolefin plastic film as the base material and acrylic polymer as the base resin of the pressure-sensitive adhesive, which is processed by a coating machine.

The real meaning of the protective film is a temporary protective measure taken to prevent surface scratches during the storage, transportation and circulation of goods, or between the processing steps of the substrate.The protective film is widely used in the surface protection of aluminum panels, aluminum-plastic composite panels, mirror effect steel plates, color panels, plexiglass panels, decorative panels, aluminum profiles, plastic steel profiles, stainless steel coils, marble materials and display screens.

The protective film for aluminum profile is based on a polyethylene (PE) film with a specific formula, polyacrylic acid (ester) resin is used as the main material of the pressure-sensitive adhesive, and several specific adhesives are coated, slit, and processed in packaging and other processes. The protective film is soft in nature, good in adhesion, easy to stick, and easy to peel off. The pressure-sensitive adhesive has good stability and will not have any adverse effects on the surface of aluminum profile to be filmed.


1. Protection during Handling and Transportation:

Aluminum profiles and plates are often subjected to rough handling, stacking, and movement during manufacturing, storage, and transportation. Without proper protection, the surfaces can easily get scratched, dented, or marred. Protective film acts as a shield, preventing direct contact with external objects and reducing the risk of damage during these processes. It ensures that the aluminum surfaces remain pristine, reducing the need for repairs or replacements.

 

2. Preservation of Aesthetic Appeal:

Aluminum is often used in architectural applications, interior design, and high-end products where aesthetics matter. Any blemishes on the surface can compromise the overall appearance and reduce the perceived value. Applying protective film on aluminum profiles and plates helps maintain their visual appeal by preventing scratches, scuffs, or stains. It ensures that the aluminum surfaces arrive in flawless condition, ready for installation or further processing.

3. Prevention of Corrosion and Oxidation:

Aluminum is naturally resistant to corrosion, thanks to its oxide layer that forms on the surface. However, this oxide layer can be compromised by exposure to moisture, chemicals, or atmospheric pollutants. Protective film creates a barrier, shielding the aluminum from these corrosive agents and minimizing the risk of oxidation. By keeping the surface protected, the film helps preserve the integrity and longevity of the aluminum profiles and plates.

 

4. Facilitation of Fabrication and Processing:

Aluminum profiles and plates often undergo various fabrication and processing steps before their final use. These may include cutting, drilling, bending, or machining. Protective film acts as a sacrificial layer, absorbing the impact and preventing damage during these operations. It reduces the risk of scratches, chips, or other forms of surface imperfections, ensuring that the aluminum remains in optimal condition throughout the manufacturing process.

 

5. Easy Removal and Residue-Free Surface:

High-quality protective films are designed to adhere securely to aluminum surfaces during storage and transportation but can be easily removed without leaving any residue behind. This simplifies the installation or fabrication process, eliminating the need for extensive cleaning or surface preparation. The residue-free removal of the film also ensures that the aluminum profiles and plates are ready for subsequent treatments such as anodizing, powder coating, or other surface finishes.

 

6. Cost Savings and Customer Satisfaction:

Applying protective film on aluminum profiles and plates is a cost-effective measure in the long run. It reduces the need for rework, repairs, or replacements caused by surface damage, which can be costly and time-consuming. By protecting the aluminum surfaces from the beginning, manufacturers can deliver products of high quality, meeting customer expectations and enhancing customer satisfaction.

 


Conclusion

Applying protective film on aluminum profiles and plates is necessary to safeguard their surfaces from damage, preserve their aesthetic appeal, prevent corrosion, facilitate fabrication processes, and ensure cost savings. The protective film acts as a temporary barrier, shielding the aluminum surfaces from scratches, abrasions, stains, and other forms of contamination. By investing in high-quality protective film, manufacturers can deliver aluminum products in pristine condition, ready for installation or further processing, and meet customer expectations for quality and aesthetics.
