Backlit PET Film: Professional Factory Provides High-quality Lightbox Backlight Materials Directly

In application scenarios such as advertising display, lightbox layout, and digital printing. Backlit PET Film is increasingly being chosen by more and more industries due to its excellent transparency, outstanding printing effect, and durability. As a professional factory with years of production experience. We are committed to providing high-quality, stable, and cost-effective backlight PET film solutions for global customers.

What is Backlit PET Film?

Backlit PET Film is a high-performance printing material designed specifically for lightbox backlight displays. It uses high transparency and high stability polyester film (PET) as the substrate, and through surface coating with a special coating system, it has excellent transparency and can achieve high-definition and high saturation image printing output.

Structural Composition

Generally speaking, Backlit PET Film is mainly composed of the following layers:

PET substrate layer: provides structural strength, dimensional stability, and weather resistance of the entire roll of material.

Coating layer (printing coating): It can be configured according to different printing methods, such as solvent based coating, UV coating, latex coating, etc., to enhance ink adsorption and image clarity.

Back treatment layer (optional): It can be treated with anti curling, anti-static, and moisture-proof properties to enhance stability during use.

Strong Printing Compatibility

Our Backlit PET Film is highly compatible with various printing devices and ink systems, and is suitable for:

Solvent/Eco solvent printer

UV printer

HP Latex Latex Latex Printer

Dye/pigment water-based spray painting (some models)

This enables Backlit PET Film to easily adapt to different countries and regions, as well as different equipment conditions, making it a highly versatile material choice in the advertising industry.

Advantages of Backlit PET Film

As a high-end printing consumable designed specifically for lightbox advertising. Our Shandong Chengji New Materials’ Backlit PET Film has demonstrated excellent comprehensive advantages in performance and practical applications.And is highly favored by advertising manufacturers, brand owners, and exhibition institutions. Here are the five core advantages of this product:

1. Excellent Light Transmittance, Making the Image More Visually Impactful

Transmittance is one of the key properties of backlight materials. The transmittance of the PET backlight film we produce is stably controlled between28% and 38% . With uniform transmittance, no shadows, and no bright spots.

When the lightbox is turned on: the image colors are brighter, the saturation is higher. And the contrast is stronger, presenting a vivid and lively advertising effect.

When the lightbox is turned off, the image remains clear and legible. Maintaining good readability without affecting the display effect.

This high-quality visual representation greatly enhances the efficiency of advertising dissemination and the professional image of the brand.

2. High Definition Printing Effect, Supporting Multiple Ink Systems

To meet diverse printing needs, we apply precise coating treatment to PET film to ensure even ink adsorption and clear imaging. Supports multiple printing methods as follows:

Solvent/weak solvent spray painting

UV printing

HP Latex latex spray painting

Some models are compatible with water-based ink

The printed image has the characteristics of high resolution, high color reproduction, and anti smudging, making it suitable for creating up close viewing advertising images, such as indoor lightboxes and brand image displays.

3. Excellent Dimensional Stability, Without Deformation or Edge warping

PET material itself has good physical strength and thermal stability. Even in:

During the high-temperature printing process

Long term exposure to light or humid environments

When printing or posting rolls of length in meters

It can maintain the material without shrinkage, foaming, or warping, and remain smooth and new even after long-term use, providing reliable guarantee for advertising installation and display.

4. Strong Weather Resistance, Suitable for Various Environments

Our backlight PET film adopts anti UV coating and moisture-proof and mildew resistant treatment, which has excellent environmental adaptability:

Resist image fading caused by direct sunlight exposure

Antioxidant, anti fungal erosion, avoiding mold spots and yellowing

Stable output effect even in outdoor or semi outdoor scenes

Therefore, it can be safely used for a long time in various environments such as shopping malls. Airports, subway stations, bus stops, outdoor billboards, etc.

5. Manufacturing with Environmentally Friendly Materials that Comply with International Standards

We are committed to green manufacturing. And the PET substrates and coating formulas. We use comply with environmental standards such as RoHS, REACH, and halogen-free. They do not contain heavy metals or harmful volatiles, and meet the high requirements of modern public spaces and brands for environmental protection and safety.

Can be applied to crowded places such as hospitals, subways, airports, shopping malls, etc

No odor or irritating gas produced, safe and reassuring

Can support partial recycling, in line with the trend of sustainable development.
