What Is Laser Film?
Laser film, often referred to as holographic pet film, is a high-precision decorative and functional material created using laser etching and optical diffraction technology. It produces a vivid, dynamic rainbow effect that changes with light and viewing angle, making it ideal for packaging, labels, laminates, and high-end surface decoration. In the case of BIYT Laser PET Film, it combines optical beauty with industrial performance—offering durability, environmental stability, and superior print adaptability.
This article explains what laser film is, how it is made, what advantages BIYT provides, and how it is applied across different industries.
1. What Is Laser pet film and How Does It Work
Laser film uses a micro-embossed surface pattern to diffract light into multiple wavelengths. The result is the signature “rainbow” or “3D holographic” effect. The base material is PET (polyester film), chosen for its excellent clarity, thermal stability, and tensile strength.
A) Structure of BIYT laser pet film
| Layer | Material | Function |
|---|---|---|
| Top coating | Protective layer / printable coating | Provides abrasion resistance, ink adhesion, and gloss control |
| Holographic layer | Nano-embossed diffraction pattern | Creates iridescent laser reflection under light |
| PET base film | High-clarity polyester | Provides strength, transparency, and stability |
| Adhesive or coating layer | Customizable | Allows lamination with paper, PVC, or other films |
Each layer contributes to the overall optical performance and processing stability. The holographic layer is created using a laser master plate and nickel embossing roller that transfers microscopic patterns onto the PET surface at high temperature and pressure.
B) Optical Principle
When white light hits the embossed structure:
Diffraction separates the light into color spectrums.
Reflection changes with angle, creating depth and movement.
Interference amplifies specific colors for a metallic brilliance.
This multi-interaction of light and structure gives BIYT Laser PET Film its three-dimensional visual impact, unmatched by conventional metallic or printed films.
2. Manufacturing Process of Laser PET Film
The production of BIYT Laser PET Film involves advanced optical replication and coating technologies. Every stage must maintain nanometer-level precision to preserve the holographic image clarity.
A) Step-by-Step Process
Master Hologram Design
Optical patterns are designed digitally using 3D modeling software.
A laser beam engraves these patterns onto a photoresist-coated glass plate.
The resulting master is used to create a nickel mold through electroforming.
Embossing
The nickel embossing roller presses the holographic pattern onto a PET film at controlled pressure and temperature.
Uniform microstructures ensure consistent diffraction effects.
Vacuum Metallization (optional)
A thin aluminum or transparent oxide layer can be added for stronger reflectivity.
BIYT also offers non-metallic laser films for eco-friendly applications.
Coating and Surface Treatment
Protective coatings or print-receptive layers are applied to enhance functionality.
The coating must remain optically transparent to preserve holographic quality.
Slitting and Quality Control
Rolls are precisely slit according to client width requirements.
Each batch undergoes spectral reflection tests and surface inspection for dust, streaks, or diffraction uniformity.

3. Applications of Laser PET Film
Laser PET Film is one of the most versatile materials in modern packaging and decoration. It bridges the gap between functional protection and visual attraction. BIYT supplies Laser PET Film in rolls, sheets, or customized patterns for OEM and ODM clients worldwide.
A) Typical Applications
| Industry | Application Example | Benefit |
|---|---|---|
| Packaging | Wrapping paper, cosmetic boxes, wine labels | Enhances brand visibility and perceived value |
| Printing | Hot stamping foil, labels, greeting cards | Adds holographic effect and anti-counterfeit security |
| Lamination | Decorative panels, PVC sheets, photo albums | Improves surface gloss and wear resistance |
| Security & Branding | Certificates, logos, authenticity seals | Difficult to replicate; protects brand identity |
| Crafts & Design | Gift wrapping, home decoration, DIY art | Vivid color play and light effects |
BIYT Laser PET Film supports multiple secondary processes:
Printing: compatible with UV, gravure, flexo, and screen printing.
Lamination: excellent adhesion to paper, PVC, ABS, and metalized substrates.
Die-cutting & thermoforming: retains pattern integrity under moderate heat.
B) Functional Benefits Beyond Aesthetics
While the rainbow visual appeal is its main attraction, BIYT Laser PET Film also offers important technical functions:
UV Protection – Blocks ultraviolet degradation on printed surfaces.
Chemical Resistance – Coating resists alcohol, oil, and cleaning solvents.
Dimensional Stability – PET base maintains shape even under heat lamination.
Moisture Resistance – Prevents delamination in humid conditions.
Recyclability – BIYT films meet RoHS and environmental safety regulations.
These attributes make the film suitable for both luxury packaging and industrial lamination where reliability is crucial.
