Transparent Heated Film (ITO Type) for Refrigerated Pastry Display

In modern bakery and food retail settings, visual appeal plays a major role in attracting customers. A beautifully arranged pastry display can boost sales—but when the glass of your refrigerated display fogs up, it hides your products and ruins that first impression.

To solve this, many display manufacturers are now integrating transparent heated films (ITO type) into their glass panels. These advanced films prevent condensation while maintaining perfect visibility, ensuring your pastries always look as fresh and inviting as they are.

What is Transparent Heated Film (ITO Type)?

A transparent heated film, or ITO film, is a thin layer of Indium Tin Oxide coated onto a transparent substrate such as PET or glass. Because ITO is both conductive and transparent, it can generate heat evenly across the surface when an electric current passes through—without blocking light transmission.

Key features include:

• High optical transparency (typically above 85%)
• Uniform, controlled surface heating
• Low power consumption
• Flexible customization options for voltage, size, and resistance

This makes ITO transparent heating films ideal for anti-fog applications, particularly where visibility and aesthetics are essential.

How Does It Work in Refrigerated Pastry Displays?

Inside a refrigerated display, the cold interior air meets warm, humid outside air at the glass surface. The result? Condensation—which causes fog and reduces visibility.

By installing an ITO transparent heating film on the inner side of the glass, the system gently warms the surface. This small temperature increase (often only a few degrees) prevents condensation while keeping the inside temperature stable for your pastries.

The working process:

1. Power is applied (12V, 24V, or 48V DC).
2. Electric current flows through the ITO layer.
3. Uniform surface heat is generated.
4. The glass temperature rises slightly, preventing moisture buildup.

The outcome is clear glass and perfect visibility, even in high-humidity environments.

Benefits of Transparent Heated Film for Display Cabinets

• Anti-Fog Performance – Keeps display glass perfectly clear in any temperature or humidity condition.
• Energy Efficiency – Uses minimal power compared to air-blower or mechanical defogging systems.
• Aesthetic Transparency – Invisible heating layer preserves the natural appearance of glass.
• Uniform Heating – Prevents uneven hot spots and ensures consistent performance.
• Long Lifespan & Durability – ITO coatings resist oxidation and corrosion for long-term reliability.
• Custom Design Options – Flexible shapes, voltages, and wiring configurations available for different display models.

Other Common Applications

While refrigerated pastry displays are one of the most popular uses, ITO transparent heating films are also widely used in:

• Supermarket refrigerator glass doors
• Beverage coolers and vending machines
• Laboratory or medical refrigeration chambers
• Vehicle mirrors and camera lenses
• Optical instruments and sensors

FAQs about Transparent Heated Film

1. How much power does a transparent heated film consume?

Power consumption depends on the film’s resistance, voltage, and surface area. Typical ITO heating films used for display glass consume between 1–5 W per square decimeter, offering excellent energy efficiency for continuous operation.

2. Can it be used on curved or double-layer glass?

Yes. ITO transparent heating films can be designed to fit flat, curved, or laminated glass structures, depending on the display cabinet design.

3. Is the heating uniform across the surface?

Absolutely. One of the main advantages of ITO films is uniform heat distribution, ensuring there are no hot spots or uneven temperature zones.

4. What voltage options are available?

Common designs support 12V, 24V, and 48V DC input, but custom voltage ratings can be provided according to your system design.

5. Does it affect the cooling performance inside the display?

No. The film’s heating is gentle and surface-focused—it prevents condensation without increasing the internal temperature of the refrigerated chamber.

6. Can the film be integrated into existing display systems?

Yes. Transparent heating films can be easily laminated or adhered to existing glass panels with minimal modification to the display cabinet structure.
