The 75 μm blue PET anti-static film can be mainly used in the following application scenarios:
Electronics Manufacturing: The film is commonly utilized in the electronics manufacturing industry, where static electricity poses a significant risk to sensitive electronic components. It serves as a protective layer or packaging material for circuit boards, electronic devices, or other static-sensitive equipment during manufacturing, assembly, or transportation. The blue color of the film can assist with visual identification and differentiation in manufacturing processes.
Cleanroom Environments: Cleanrooms in industries such as pharmaceuticals, biotechnology, or microelectronics require materials that minimize static charge generation and accumulation. The 75 μm blue PET anti-static film is often employed in cleanroom environments for applications like curtains, partitions, or covers. Its anti-static properties help maintain a controlled electrostatic discharge environment, ensuring the integrity of sensitive equipment or products. The blue color can also help distinguish cleanroom areas or equipment.
Static-Sensitive Product Packaging: The film is suitable for packaging static-sensitive products, including electronic components, integrated circuits, or delicate instruments. By incorporating the 75 μm blue PET anti-static film into the packaging, it acts as a protective barrier against static charges, preventing potential damage to the enclosed items. The blue color can aid in easy identification and differentiation of the packaged products.
Printing and Graphics: The film finds applications in printing and graphics, particularly where static electricity can interfere with the process or cause damage to delicate materials. It serves as a protective layer for printed materials, preventing issues such as static-related ink smudging or improper toner transfer. The blue color of the film can also add aesthetic appeal or serve as a contrasting background for printed designs.
Display and Signage: The 75 μm blue PET anti-static film is suitable for applications in displays and signage. It can be used as a protective layer for screens, touch panels, or signage boards, providing an anti-static shield to prevent static-related issues and maintaining the clarity and visibility of the display. The blue color of the film can also be utilized for visual effects or to convey specific information.
It's important to note that while the 75 μm blue PET anti-static film is designed to address static-related concerns, its suitability for specific applications should be determined by considering the requirements and guidelines of the industry or manufacturer.
The main feature of PET anti-static coated film is its ability to prevent the buildup of static electricity. It has a conductive coating on one or both sides of the film, which allows charges to dissipate and prevents static buildup. This results in improved handling, processing, and protection of sensitive components and products. The main colors of the film commonly used in application scenarios are transparent or translucent (colorless).
However, other colors such as pink, blue, and yellow may also be used, depending on the application. The color is mainly used for identification purposes to differentiate between different types of films and facilitate quality control.
To coat an antistatic fluid onto an already produced PET film, the PET film is first unwound from its original roll and passed through
a coating applicator that applies the antistatic fluid to the film's surface. This can be done using various coating methods such as
gravure, reverse gravure, Mayer rod or air knife, depending on the viscosity of the antistatic fluid and the desired coating thickness.
After the coating process, the PET film is then passed through a drying oven to remove the solvent from the antistatic fluid.
Once the solvent is evaporated, the film is rewound onto a new roll.
It is important to note that the effectiveness of this coating process depends on the type of antistatic fluid used and its compatibility
with the PET film. The process should also be carefully controlled to maintain a consistent coating thickness and avoid any defects or
inconsistencies in the final product.
