Protective Film For Electronics and EV Battery

The electronic protective films, we mainly refer to temporary surface protective films used in the manufacturing process of electronic components. The main applications are glass-based display screens, such as touch panels, LED displayer, mobilephone screens, as well as plastic optical sheets, light guide plates, PC sheets, PMMA boards, etc. At the same time, we also have specialized products for certain electronic components that need to withstand high temperatures or anti-static required.

We have 4 film substrates to meet the surface protection needs of different application scenarios, including premium electronic protective film.

PE protective film
PET protective film
CPP protective film
Co-extruded self-adhesive protective film

Tape slitting, releasing lamination and die-cutting services are available upon request for protective film electronics.

Applications of Protective Film For Electronics

Protective film, specifically protective film for electronics, has become an indispensable and important part of the whole life cycle of modern electronic products from production to daily use by consumers. It is no longer just a simple plastic film, but a precision material that integrates protection and function.

The application of protective film in the entire industry chain of electronic products is mainly manifested in the following links and components:

Manufacturing & Transportation (Process Protection Film)

Donlee protective film is mainly used to protect the shell of the product, metal/plastic frame, glass back panel, screen, battery cover, etc., in the metal (such as aluminum alloy, stainless steel) or plastic parts after being cut and polished by CNC, in the whole process of anodizing, spraying, electroplating, silk screen printing and other surface treatment, Donlee protective film is used, it can play the role of selective protective film, so that in the local surface treatment, protect the area that does not need to be processed.

Each Workpiece During Turnover and Storage Between Processes

At the same time, Donlee protective film also provides full protection for each workpiece during turnover and storage between processes, preventing scratches, bumps or fingerprints on the finished high-gloss surface. Once the product is assembled and ready to be delivered to the consumer, this temporary surface protection film is removed to reveal a flawless surface.

Screen & Display Panel (Screen Protection Film)

Donlee screen protection film are used for screen parts as glass screens for smartphones, tablets, laptops, smartwatches, TVs, monitors, etc, the screen is the most vulnerable and frequently touched part of electronic devices, and is vulnerable to scratches, impacts, oil, and dust. Our screen protector acts as a sacrificial barrier to bear these injuries directly.

Customized Factory for On-Demand Production

Donlee is a customized factory for on-demand production, after fully understanding the customer's use conditions, applying expectations and completing product matching, we will provide surface protection solutions accordingly to meet protective film needs of customers.

Donlee Protective Film Can Be Customized According to Needs

Adjustable viscosity: Donlee offers products with different viscosities, from ultra-low viscosity to medium and high viscosity to meet the requirements of pasting and peeling in different scenarios for protective film for electronics.

Shape Customization: Our own dust-free die-cutting workshop can process and pre-cut the protective film into various complex shapes to fit the protected area of specific components for precise protection, including protective plastic film for electronics.

Diverse Materials: There are various materials such as PE, PET, CPP, etc., with different tensile strengths, temperature resistance, and cleanliness, suitable for various application scenarios.

In the manufacturing process of electronic products, protective films have long evolved beyond their simple physical properties to become a critical process aid material. It silently yet crucially guards the appearance and value of the product, and is an indispensable part of a modern, efficient production line. As a leader in China's protective film manufacturing industry, Donlee is proud to be the setter and drafter of national protective film industry standards, serving expansive customer group at home and abroad with our professional R&D and manufacturing capabilities for protective plastic film for electronics.

Protective Film For Electronics Production Process

The value of protective film is far more than just a "layer of film", it is a key factor in ensuring production efficiency, controlling costs and improving quality.

A good quality Donlee protective film electronics Significantly improve product yield as its core advantage. Scratches, indentations, and stains on the appearance of electronic products are all serious cosmetic defects, which can lead to product down-grading or even scrapping. By providing physical isolation, Donlee protective film greatly reduces losses caused by cosmetic issues and directly improves the output yield of the production line, which is crucial for the manufacturing industry.

Secondly protective film allows components and semi-finished products to be safely and efficiently rotated between processes. Without a protective film, workers and automation equipment need to handle every component with very care, which can seriously slow down production. The qualified Donlee protective film provides a "sense of security" that allows logistics and operations to proceed more quickly.

Thirdly, although a Donlee electronic protective film electronics itself has material costs, it avoids the huge hidden costs caused by surface damage as

Rework Cost: For minor scratches that can be repaired, it is necessary to arrange personnel to polish and other treatments, which consumes manpower, time, and space.
Scrap Cost: For irreparable damage, the material and production cost of the entire part is lost.
Quality Cost: Defective products that go to the market can lead to customer complaints, returns, and warranty claims, damaging brand reputation and costly.

Therefore, the use of reliable high-quality Donlee electronic protective film is an excellent cost control strategy.
