Features and Application Fields of High Light Shielding Tape

Light shading tape is a tape that uses a special environmentally-friendly substrate, whose surface is specially treated to achieve partial or complete shading, and back is coated with strong and durable adhesive on one or both sides. Light shielding tape black single/double-sided tape has light  shielding function, using a black film made by a unique printing process as the base material, and has excellent shielding and insulating properties.

Light shading tape is also called opaque tape, and is also called shading material widely. It is an adhesive material that can be used to wrap the borders of LED and LCD display screens to shield the light source and block the light source from penetrating. Its shading performance is superior, with soft material, firm paste, and it is not easy to warp. It is a low-cost, good-effect accessory product used on LED.

Classification of light shading tape:

Classified by material: shading paper tape, shading film tape;

Classified by color: bright silver shading tape, matte silver shading tape, black silver shading tape, black shading tape, black and white shading tape, silver shading tape, white film (white shading tape);

Classified by the adhesiveness: single-sided adhesive light shading tape, double-sided adhesive shading tape；

Classified by the degree of shading: semi-transparent shading tape, completely opaque shading tape;

Classified by the substrate: single-layer release bottom shading tape, double-layer release bottom shading tape.

Features of light shading tape:

1. The black PET substrate surface can be treated with matt finish;

2. Perform 180° peel test under the condition of 25μm PET polyester film mounting and stretching speed of 300mm/min;

3. It is processed in a clean environment of class 1000, with excellent cleanliness;

4. The black coating is used for printing, which has excellent opacity. The black coating has excellent insulation;

5. Storage temperature: 5~30℃. Avoid placing it under direct sunlight, low temperature (below 0℃), high temperature (above 40℃), and high humidity (above 70%RH).

How to choose light shielding tape

When choosing light shielding tape, it's essential to consider several key factors to ensure that the tape meets your specific application requirements. As a professional high temperature tape manufacturer, here’s how we recommend selecting the right light shielding tape for your needs:

1. Material Type
Light shielding tapes are often made from materials like aluminum foil, copper, or carbon-based films. The material you choose will depend on the type of light or radiation you need to block. Aluminum foil is commonly used for general light shielding, while copper may offer additional electromagnetic interference (EMI) protection.

2. Adhesive Properties
The adhesive strength is crucial to ensuring the tape stays in place during use. Consider whether you need a permanent or removable adhesive. For sensitive surfaces or temporary applications, a low-tack adhesive might be more appropriate, while high-performance, permanent adhesives are ideal for industrial uses that require strong bonding. Make sure the adhesive can withstand environmental factors like temperature, humidity, and UV exposure.

3. Thickness and Durability
The thickness of the tape impacts both its shielding effectiveness and its durability. A thicker tape may provide better shielding but can be less flexible, while thinner tapes are more flexible but may be less effective at blocking light. Consider the environment in which the tape will be used—whether it will be exposed to wear and tear, chemicals, or extreme temperatures—and choose a tape that balances durability with performance.

4. Application Environment
Think about the specific environment where the light shielding tape will be applied. If it's for indoor use, a standard adhesive may suffice, but for outdoor or high-temperature environments, you'll need a tape with high-temperature resistance and UV stability. If the tape will be used in medical, electronics, or sensitive equipment settings, ensure the material and adhesive are 5. non-reactive and safe.

5. Width and Length
Consider the required dimensions for your project. Light shielding tapes come in various widths and lengths. Choose the size that fits your application and minimizes waste. Custom widths and rolls are available for larger projects or specialized applications.

6. Regulatory Compliance
Ensure the tape complies with relevant industry standards, such as fire safety regulations, medical certifications, or specific industry guidelines. If your application involves safety-critical environments, confirm that the tape is certified for use in such settings.
