Low-E Glass Protective Film
- Low-emissivity (Low-E) glass features a delicate silver-based coating that provides excellent thermal insulation and energy efficiency.
- However, the exposed edges of off-line Low-E glass are highly susceptible to oxidation.
- Our Low-E Glass Protective Film is specifically engineered to address this critical challenge.
- Advanced edge sealing protection
- High air barrier capability
- Patented material structure
- Custom thickness, width and length
- Custom logo printing up to 8 colors
Low-E Glass Structure
- A typical Low-E glass structure consists of several main layers:
1. Base Glass Substrate
Typically clear float glass providing structural strength and optical clarity.
2. Low-E Coating Layer
Ultra-thin metallic layers (primarily silver) applied to reflect infrared heat while allowing visible light transmission.
3. Protective Dielectric Layers
Oxide coatings deposited above and below the silver layer to enhance durability, adhesion, and optical performance.
4. Multi-Layer Configuration
Advanced Low-E glass may include double or triple silver layers to achieve higher energy efficiency and improved solar control.
5. Gas-Filled Cavity
Combined with spacer systems and inert gas (such as argon) between panes to further improve energy efficiency.
Why Low-E Glass Needs Protective Film?
Low-emissivity (Low-E) glass features a delicate silver-based coating that provides excellent thermal insulation and energy efficiency.
However, during storage, transportation, and pre-processing stages, the exposed edges of off-line Low-E glass are highly susceptible to oxidation.
Contact with air and moisture can rapidly degrade the silver layer, leading to coating deterioration, reduced optical performance, and potential defects in subsequent processing such as:
- Tempering
- Insulating
- Lamination
To address this critical challenge, our Low-E glass protective films are applied specifically to seal the glass edges.
Main Features of Our Low-E Glass Protective Film
1. Patented Material Structure
Engineered with a patented multi-layer material structure that ensures optimal adhesion, durability, and stability.
2. Edge Sealing Protection
Specifically designed for edge applications, the film effectively seals the edges of Low-E glass to prevent oxidation and contamination.
3. High Air Barrier Performance
In addition to edge sealing, our protective film also has a high air barrier capability, effectively preventing oxygen components in the air from entering the air cavity to oxidize the silver plating layer.
