ABOUT 1 PLY PRIMARY FILM
Primary film, a type of car window film, is designed to offer basic yet essential performance. Made from a single layer (1-ply) of dyed material, it provides fundamental heat rejection to reduce interior temperature and block harmful UV rays, enhancing comfort and protecting occupants. The dyed construction ensures a consistent color that resists fading over time. While maintaining clear visibility, it adds a subtle tint to windows, balancing aesthetics and functionality. Ideal for budget-conscious users, primary film delivers reliable sun protection and moderate heat reduction, making it a practical choice for everyday vehicles seeking simple yet effective window tinting solutions.
What are the differences between different types of window film?
| Type | Core Structure Characteristics | | Applicable Scenarios |
| Dyed Film | Only dye layer + glue layer | 1-1.8mil | Low-end model, limited budget |
| Metallic Film | Multilayer metal + polyester substrate | 2-3mil | In high temperature areas, pursue high insulation |
| Nano Ceramic Film | Nano-ceramic particles + PET layer | 2-4mil | High-end models with signal penetration |
| Privacy Film | Dark dye layer + one-way perspective technology | 2-3mil | Commercial/luxury cars, privacy oriented |
The main structure of car window film
What are the benefits of car window film?
-
-
- Dyed Polyester Base Layer: The core material is a thin, durable polyester film treated with dyes to achieve tinting effects. The dye is embedded during production, providing consistent color and basic UV and heat rejection properties.
- Adhesive Layer: A layer of pressure-sensitive adhesive is applied to one side of the polyester film, allowing easy installation on car windows. This adhesive is designed for clarity and secure bonding without excessive residue.
- Protective Coating (Optional): Some primary films include a lightweight protective layer to resist scratches and minor abrasions, enhancing longevity while maintaining transparency.
This simple structure focuses on affordability and basic functionality, making it suitable for users seeking straightforward sun protection and aesthetic enhancement.
Why Use 1 PLY Primary Film:
- Cost Efficiency: The single-layer design eliminates complex manufacturing processes and materials, making it an economical choice for budget-conscious users who need basic sun protection without high costs.
- Straightforward Installation: Its simple structure is easy to handle during installation, reducing the risk of errors like bubbling or misalignment. This makes it ideal for DIY projects or quick professional applications.
- Optimal Clarity: With only one layer, the film maintains high transparency, ensuring clear visibility for safe driving while adding a subtle tint. This complies with legal regulations in regions that restrict dark window tints.
- Lightweight Flexibility: The single-ply design adapts well to curved or irregular window shapes, fitting various vehicle models seamlessly without compromising durability or performance.
- Essential Functionality: Primary film focuses on core benefits like blocking harmful UV rays and reducing interior heat moderately, meeting daily needs for comfort and protection without unnecessary layers or features.
In essence, 1-ply primary film offers a practical, cost-effective solution for users seeking reliable basic performance with ease of use and installation.
Primary Film is completely harmless to humans.
- Non-Toxic Materials: It typically uses dyed polyester and adhesives that are free of harmful chemicals like formaldehyde or volatile organic compounds (VOCs). These materials are rigorously tested to meet safety standards, ensuring no toxic emissions into the vehicle interior.
- Compliance with Regulations: Most primary films are designed to comply with international environmental and safety regulations (e.g., REACH in the EU), ensuring they do not pose risks to human health or the environment during production, use, or disposal.
- No Hazardous Installation Process: The film’s adhesive is water-based or pressure-sensitive, requiring no harsh solvents or chemicals during installation. This eliminates fumes or residues that could harm installers or vehicle occupants.
- Stable Performance: The single-layer design lacks reactive components, meaning it remains chemically stable over time. It does not degrade into harmful substances when exposed to sunlight, heat, or moisture, ensuring long-term safety.
- Safe for Vehicle Components: The film adheres securely without damaging window glass or electronic systems (e.g., defrosters), and it can be removed without leaving toxic residues or causing surface damage.
In summary, 1-ply primary film prioritizes safety through non-toxic materials, regulatory compliance, and a hazard-free design, making it a safe choice for vehicle use.
