Ysmlite:Luminous Film Manufacturer Providing Leading Services

What is Photoluminescent Film? A Complete Explanation of the Glow-in-the-Dark Film Principle

Luminous film, a type of photoluminescent film, is a functional material that can emit light automatically in the dark. It absorbs ambient light energy, stores it, and then releases a gentle glow for several hours without requiring an external power source.

ysmlite’s photoluminescent film uses a highly transparent PET base film combined with proprietary rare-earth aluminate phosphors. Nanometer-level dispersion technology ensures uniform distribution of luminous particles, avoiding dark spots and maintaining even, stable glow. This technology provides 

several advantages:

• ▸It requires only 5-10 minutes of light absorption to continuously glow for 8-12 hours
• ▸Initial brightness reaches industry-leading levels (≥80mcd/m²)
• ▸The luminous lifespan exceeds 10 years, suitable for long-term use
• ▸Multiple glow colors are supported, including standard blue-green (approximate wavelength 520nm) and customized orange-red, pink-purple hues

The luminous film is available in various structures such as adhesive-backed, non-adhesive, heat transfer, and peel-and-stick versions, fitting different substrate types including flat and curved surfaces.

Production Process of ysmlite’s Photoluminescent Film

ysmlite’s photoluminescent film undergoes a scientifically controlled production process to ensure high brightness, longevity, and excellent physical properties. The main production steps include:

• ▸Substrate Selection:High-transparency PET film is used as the base, offering good flexibility, tear resistance, and weather durability, suitable for outdoor and curved-surface applications. The substrate complies with RoHS and REACH environmental standards and is non-toxic.
• ▸Luminescent Layer Preparation:The company’s proprietary rare-earth aluminate phosphor provides long afterglow characteristics. The phosphor particles are uniformly dispersed at the nanometer scale on the base film, preventing dark spots and ensuring consistent glow.
• ▸Protective Functional Coatings:A UV anti-aging coating is applied to delay yellowing and brittleness caused by sunlight, extending outdoor life by over 50%.A 3H hardness wear-resistant coating protects against scratches and preserves clarity.
• ▸Adhesive Layer Design:Multiple adhesive options are available, including permanent strong adhesive, removable weak adhesive, heat transfer adhesive, and peel-off adhesive, suitable for various installation environments.
• ▸Slitting and Die-Cutting:Supports customized widths, lengths, and irregular shapes such as circles, waves, and hollow patterns to meet diverse customer needs.
• ▸Strict Quality Testing:Each batch passes brightness testing (≥80mcd/m²), peel strength testing (≥2.5N/cm), and high-low temperature cycling (-20°C to 80°C) to ensure consistent performance.

Wide Applications of ysmlite’s Photoluminescent Film

ysmlite’s PVC/PET luminous film performs excellently across multiple industries and scenarios, addressing various safety and decorative requirements:
